Assessment of Cardiovascular and Peripheral Vascular System Flashcards
Complete examination of the cardiovascular system consists of _____________________________________________ to evaluate functioning of the heart and vessels.
history taking, inspection, palpation, percussion, and auscultation
is defined as the succession of coordinated events taking place in the heart during each beat
Cardiac Cycle
Each heart beat consists of two parts:
SYSTOLE and DIASTOLE
Ventricular contraction
SYSTOLE
Ventricular relaxation
DIASTOLE
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
is the amount of blood the heart pumps (SV) through the circulatory system in a minute (HR)
Cardiac Output
Cardiac Output formula
Stroke Volume x Heart Rate = Cardiac Output
Borders of the Heart
Upper Border
Right Border
Lower Border
Left Border
- is formed by the 2 atria
Upper Border
it is conceled by ascending aorta and pulmonary trunk
Upper Border
is formed by right atrium
Right Border
is formed mainly by right ventricle + apical part of left ventricle
Lower Border
is formed mainly by left ventricle + left auricle
Left Border
Four (4) Heart Sounds
S1. S2, S3, S4
Marks the beginning of systole (end of diastole)
First heart sound: S1
It resembles to spoken word “Lub”
First heart sound: S1
Loudest at the apex and lower left sternal border
First heart sound: S1
S1 is loudest at?
at the apex and lower left sternal border
Marks the end of systole (beginning of diastole)
Second heart sound: S2
It resembles to spoken word “Dub”
Second heart sound: S2
Loudest at the base
S2
S2 is loudest at?
at the base
Heard in early diastole
Third heart sound: S3
This may be a normal sound in some people but in people with heart conditions may indicate heart failure.
Third heart sound: S3
S3 may be a normal sound in some people but in people with heart conditions may indicate
heart failure
Low-intensity sound heard just before S1 in the cardiac cycle
Fourth heart sound: S4
The sudden slowing of blood flow by the ventricle as the atrium contracts causes this sound.
Fourth heart sound: S4
S4 is caused by
sudden slowing of blood flow by the ventricle as the atrium contracts
May be a sign of heart disease.
Fourth heart sound: S4
S4 heart sound may be a
sign of heart disease
