ASSESSING CARDIOVASCULAR AND PERIPHERAL VASCULAR SYSTEM Flashcards
formed by left ventricle
left border
is defined as the succession of
coordinated events taking place in the heart
during each beat
cardiac cycle
Complete examination of the cardiovascular
system consists of
history taking, inspection,
palpation, percussion, and auscultation to
evaluate functioning of the heart and vessels.
Each heart beat consists of two parts:
systole
diastole
Ventricular contraction
systole
Ventricular relaxation
diastole
is the amount of blood the heart
pumps through the circulatory system in a
minute.
cardiac output
formula for cardiac output
Stroke Volume x Heart Rate = Cardiac Output
is the volume of blood pumped
out of the heart during each Systolic Cardiac
contraction.
*Stroke Volume
is the speed of heartbeat measured
by the number of contractions (beats) of heart
per minute (bpm).
*Heart Rate
Marks the beginning of systole (end of diastole)
It resembles to spoken word “Lub”
Loudest at the apex and lower left sternal border
First heart sound: S1
Marks the end of systole (beginning of diastole)
It resembles to spoken word “Dub”
Loudest at the base
Second heart sound: S2
Heard in early diastole
This may be a normal sound in some people but
in people with heart conditions may indicate
heart failure.
▪Third heart sound: S3
Low-intensity sound heard just before S1 in the
cardiac cycle.
The sudden slowing of blood flow by the ventricle
as the atrium contracts causes this sound.
May be a sign of heart disease.
▪Fourth heart sound: S4
