Cardio examination 2 Flashcards
normal HR
● Adults: 60 to 100 bpm (average is 80 bpm); 40 to 60 bpm in aerobically trained
individuals
● Newborns: 80 to 180 bpm (average is 130 bpm)
tachycardia
● Compensatory tachycardia: due to volume loss (surgery, dehydration)
● Postural tachycardia syndrome: sustained HR increase of ≥30 bpm within 10 minutes
of standing
bradycardia
<60 bpm
pulse abnormalities
weak/thready, irregular, bounding full pulse
irregular pulse
variations in force or frequency; can be due to arrhythmias, myocarditis
weak/thready
low SV, cardiogenic shock, increased peripheral resistance, severe CHF
bounding pulse
increased SV, shortened ventricular systole, decreased peripheral
pressure, aortic insufficiency, anxiety, fever, hypertension (HTN), exercise
aortic valve
2nd intercostal space (ICS), right sternal border
pulmonic valve
2nd ICS, left sternal border
tricuspid
4th ICS, left sternal border
mitral valve
5th ICS, left midclavicular line
➤ Where you will hear S3 if present
➤ Also called apical pulse; point of maximal impulse
erbs point
auscultation location for heart sounds and heart murmurs located at the
3rd left ICS
Normal heart sounds
S1
S1 = “Lub”: mitral and tricuspid valves (AV valves) closing → onset of systole
-Decreased sound in first-degree heart block
normal heart sounds S2
S2 = “Dub”: aortic and pulmonic valves (semilunar valves) closing → onset of
diastole
➤ Decreased sound in aortic stenosis
● Systole occurs between S1 and S2
● Diastole occurs between S2 and S1
Abnormal sounds: Gallops
Occurs at S3 and S4
S3 = “kenTUCKy” (S1–S2–S3)
➤ Ventricular gallop
➤ Associated with ventricular filling after mitral and tricuspid valves open
Low-frequency turbulence; heard during early diastole
➤ Hallmark sign of CHF
➤ May be normal in children and young athletes
S4 = “TENNessee” (S4–S1–S2)
➤ Atrial gallop
➤ Associated with abnormal ventricular filling and atrial contraction
Low-frequency turbulence; heard during late diastole
➤ Associated with MI, HTN, and LV hypertrophy
systolic murmur
turbulence between S1 and S2; valvular disease (mitral valve pro-
lapse), aortic stenosis, or may be normal
➤ Abnormal “swishing” sound is heard instead of “lub”; heard as “lush”
diastolic murmur
turbulence between S2 and S1; aortic and pulmonary regurgitation
or mitral stenosis
➤ Fairly uncommon
murmur grades
grade 1 (softest) to grade 6 (audible with stethoscope lifted off
chest)
thrill
abnormal tremor with vascular or cardiac murmur; felt with palpation
stenotic valve
impaired opening
regurgitant valve
impaired closing
