BACKGROUND INFORMATION SIGNIFICANT FOR RISK FACTORS:

 

 

 

 

·         Hypertension Classifications:  NIH, 6th Report, 1997

                                                                                                                                                               

Adults:   Category                                               Systolic (SBP)     Diastolic (DBP)  

·         Normal                                                           <130                        <85

·         High normal                                                  130-139                   85-89

·         Hypertension

Stage I (mild)                         140-159                   90-99       Lifestyle changes

Stage II (moderate)              160-179                   100-109   Lifestyle changes

Stage III (severe)                  180-209                   110-119   Medication

Stage IV (very severe)         ³210                        ³120

                                                                                                                                                               

Children:

·         Normal:                          < 90th %ile              systolic & diastolic

·         High normal:                 90-95th %ile            systolic & diastolic

·         Hypertension:               > 95th %ile              systolic &

                                                                                                                                                                 

 

 

 

·         Arm Blood Pressure: May be 5-10 mm Hg higher in

                right arm than left arm:  greater differences between right &

                left arm may be associated with congenital aortic stenosis or

                acquired conditions, such as aortic dissection or obstruction

                of arteries of the upper arm

                                Supravalvular Aortic Stenosis:        HTN in Rt. Arm

                                & hypotension in lt. Arm

                               

 

               

·         Leg Blood Pressure:  Arm & leg blood pressures are about

                equal during the first year of life & after that time the leg blood

                pressure is 15-20 mm Hg higher than arm blood pressure

                                Coarctation of Aorta:          Leg BP lower than arm BP

 

 

 

·         Pulse Pressure:

difference between systolic & diastolic blood pressures:

·         usual adult pulse pressure is between 30 – 40 mm Hg 

(even as high as 50 mm Hg):  example:  pulse pressure

may widen with systolic hypertension, may widen with

increased intracranial pressure

·         may be wider in children  (between 20 – 50 mm Hg):

examples:  wide pulse pressure more than 50 mm Hg in

children may indicate congestive heart failure:

narrow pulse pressure less than 10 mm Hg  may

indicate aortic stenosis

 

 

 

·         Orthostatic Hypotension:          Decrease in systolic BP of

                20-30 mm Hg or more when changing from supine to standing

                position, & increase in pulse of 10-20 bpm:  sudden drops may

                result in fainting.  Dizziness & faintness from orthostatic

                hypotension may occur when taking antihypertensive

medications, volume depleted, confined to bed or in the elderly

 

 

 

·         Korotkoff sounds:       Turbulant sounds of partial obstruction

of arterial flow

Phase I:                  sharp tapping sound (systolic)

Phase II:                 change to soft swishing sound

Phase III:               sounds more crisp & intense

Phase IV:               muffled tapping (first diastolic)

closer to true diastolic in children:

record for diastolic in children <13 yrs

Phase V:                 cessation of sound (2nd diastolic)

closer to true diastolic in adults:

record for diastolic in children >13 yrs

& adults

American Heart Association recommends

Recording systolic/1st diastolic/2nd diastolic

 

·         Auscultatory gap:

silence caused by disappearance of Korotkoff sounds after

initial appearance and are then heard 10-15 mm Hg later:

can be mistaken for lower SBP reading (point of reappearance):

can be associated with decreased peripheral flow, such as

hypertension or aortic stenosis

 

 

·         Pulse:  Common Definitions & Abnormalities

 

Pulse Deficit:               A difference between the apical &

peripheral pulse.(peripheral pulse rate subtracted from

apical pulse): normally “zero;” or no difference: 

a pulse deficit indicates weak pulses/heart beats

 

Bigeminal Pulse:        Normal pulse is followed by premature

contractions, which are weaker than the normal pulse. 

Rhythm is irregular.  Possible causes:  premature ventricular

contraction or atrial contraction

 

Pulses Alterans:         Pulses have large amplitude beats

followed by pulses of low amplitude.  Rhythm remains

normal.  Possible cause:  left sided congestive heart failure

 

Pulsus Paradoxus:      An exaggeration of the normal

paradoxical pulse, defined as a normal fall of approximately

5 mm. Hg. in systolic arterial blood pressure during inspiration,

as compared to expiration.  A difference of more than

10 mm. Hg  is abnormal pulsus paradoxus.  Possible causes:

cardiac tamponade, constrictive pericarditis, obstructive

lung disease.  It is tested better by BP evaluation of systolic

pressure than by pulse palpation.

 

Palpitations: Unpleasant sensations of awareness of

the heartbeat:  described as skipped beats, racing, fluttering,

pounding or irregularity:  may result from rapid acceleration

or slowing of heart, increased forcefulness of cardiac

contraction:  not necessarily associated with heart disease

 

 

 

 

·         Cholesterol Issues

 

·         Serum Lipid Levels:                          

·         Used to determine risk for coronary heart disease

·         TCHOL:                Total cholesterol                  Elevations increase risk

·         TG:                         Triglycerides                         Elevations increase risk

·         LDL:                      Low density lipoprotein      Elevations increase risk

·         HDL:                      High density lipoprotein     Elevations decrease risk

 

 

Serum Lipids:  Optimum Levels

Measured in mg/dl

                                                                                                                               

                                                                Adults                                    Children

                TCHOL (acceptable)           <200                                        <170

                                 (borderline)          200-239                                   170-199

                                (high)                     >240                                        >200

 

                Triglycerides                       <200                                        <150

 

                LDL        (70% of total)        <130                                        <110

                                (acceptable)          <110

                                (borderline)           110-120

                                (high)                     >130

                                Atherogenic

 

                HDL       (25% of total)        >35                                          >35

                                Protective

                                                                                                                               

 

 

·         Cholesterol & Children:

·         Universal screening not recommended

·         Yes:                Family history of cholesterol >240,

premature CVD

·         Yes:                Lifestyle risk factors

 

 

CARDIAC CONSIDERATIONS

 

·         Heart

Base:      (upper)   aortic & pulmonic area

Apex:      (lower)    mitral area

Left side:                high pressure flow

Right side:             low pressure flow

·         Pericardium (pericardial sac)

·         Anchors:      

Bottom to diaphragm

Top to upper sternum

·         Visceral or epicardial sac (inner lining):

Insensitive to pain

·         Parietal (outer lining)

Innervated by phrenic nerve & sensitive to pain

 

 

·         Impulse Conduction:

·         Heart is innervated by autonomic nervous system

·         Sympathetic:                 stimulates

·         Parasympathetic:          slows

·         Sinoatrial (SA) node:   located in right atria,

Generates impulses that travel through the

conduction system & produce cardiac muscle contractions

·         Atrioventricular (AV) node:       located  in the atrial septum

·         Bundle of His:               right & left bundle branches

·         Purkinjie fibers:             located in ventricular myocardium,

where ventricular contraction takes place

 

·         Location of left ventricular apex & PMI (point of maximum impulse)

 

·         Adults:           5th ICS, MCL

·         Infants:          4th ICS, left of MCL

·         Pregnancy:   PMI moves 1-2 cms left of MCL & up to

4th ICS

 

·         Cardiac Auscultation:                listening areas

·         Stethoscope:                 diaphragm:            high pitched sounds

bell:                         low pitched sounds

listen:                     to one sound at a time,

                                over valvular areas

               

·         Aortic:                           2nd ICS, RSB          S2 is loudest

·         Pulmonic:                     2nd ICS, LSB           S2 is loudest

·         Erbs Point:                    3rd ICS, LSB

·         Tricuspid:                     4th ICS, LSB           S1 is loudest

·         Mitral (Apex)                5th ICS, MCL          S1 is loudest

 

 

·         Consider Cardiac Cycle When Listening

 

·         S1:                  Represents ventricular contraction & ejection:

S1 sound is produced by closing of

Atrial ventricular (AV) valves:

Tricuspid & Mitral valves

 

·         S2:                  Represents ventricular relaxation & filling:

S2 sound is produced by closing of

Semilunar valves:

Aortic & Pulmonic valves

 

·         When a clicking or snapping sound is heard, it

Usually means that damaged valves are heard

Upon opening rather than upon closing (which

Essentially reverses the valvular sound patterns:

 

S1:          called an “ejection click”

The sound is produced by the opening

of damaged semilunar valves

(aortic or pulmonic)

 

S2:          called “opening snap”

                The sound is produced by the opening

                of damaged atrial ventricular (AV) valves

                (tricuspid or mitral):

                Example:                Mitral stenosis produces

                                                An S2 opening snap

 

 

 

·         Continued:  Cardiac Cycle:

 

S3:          Can be normal in children & young adults

                Over 30 years of age:           “Ventricular Gallop”

                Associated with CHF

 

                Rhythm simulation:

 

                SLOSH- ING- IN   TENN- E-   SSEE

                S1            S2     S3 S1         S2   S3

 

 

S4:          Possible to be normal in children & young adults

                Over 30 years:       noncompliant or stiff ventricle

                Hypertrophy of ventricle, CHF, CAD

 

                Rhythm simulation:

 

                A-   STIFF- WALL              KEN-  TU-  CKY

                S4    S1         S2                     S4         S1    S2

 

 

 

 

·         Sinus Arrhythmia:     Normal rhythm

Normal splitting of S2

·         Refers to the physiologic splitting of S2

(reflects the time delay between closure

of the aortic and pulmonic valves)

·         S2 split “widens” or increases during

an inspiratory breath (heart rate slows)

·         S2 split “narrows” or decreases with

breath expiration (heart rate increases)

 

 

 

·         Abnormal S2 split & selected examples:

See text for additional examples

 

·         Wide:             delayed emptying of right ventricle &

delayed closure of pulmonic valve

Examples:  Right Bundle Branch Block,

Pulmonic stenosis

 

·         Fixed:             split of S2 is affected by respiration

Example:  ASD

 

·         Paradoxical:

Physiologic split reverses:

Narrows with inspiration &

Widens with expiration

Example:  Left Bundle Branch Block,

Aortic Stenosis

 

 

·         Jugular Venous Pressure

 

·         Reflects pressures in right side of heart

·         Assess the internal jugular vein if possible

·         Venous pulsations are visible, but not palable

·         Pulsations best visible with patient sitting a

45 degree angle  (45-60)

·         Measure highest level of pulsations,

From the sternal angle

·         Pressures > 3-4 cms above the sternal angle

are elevated

SPECIAL MANEUVERS FOR EVALUATION OF SYSOLIC MURMURS

DIASTOLIC MURMURS ARE ALWAYS PATHOLOGICA

 

·         Respiration

·         Inspiration - venous return enhanced &

right-sided murmurs may increase

·         Expiration - Decrease in venous return &

right- sided murmurs may decrease. 

Left sided murmurs may increase

 

·         Valsalva Maneuver

During straining phase, venous return diminishes,

 left ventricular volume & BP are  reduced

Hypertrophic obstructive cardiomyopathy &

mitral valve prolapse murmurs increase &

 aortic stenosis murmurs decrease

 

·         Standing from Squatting

Left ventricular volume is reduced secondary to reduced venous return

Mitral valve prolapse may be enhanced & in absence of murmur

may produce mitral insufficiency murmur.

Hypertrophic obstructive cardiomyopathy murmur

increases & aoritc stenosis murmur decreases

 

·         Passive Leg Raising

Increased venous return & increased left

ventricular & right ventricular volume

May enhance murmur of tricuspid regurgitation

·         Handgrip

After one minute of patients strongest possible grip

May reduce murmur of aortic stenosis,

increase murmur of aortic regurgitation

& mitral regurgitation.

 May increase murmur of VSD

 

 

·         Arterial Occlusion

Bilateral, upper arms, 20-40 mm hg above BP

Intensity noted after 20 seconds

May increase murmur of mitral regurgitation
