Assessing Cardiovascular Functions Flashcards
1
Q
Heart beat (rate)
A
Number of times the heart beat in a minute
- taken in number of places
- average adult pulse 60-100 bpm
2
Q
Radial pulse
A
Thumb side of inner wrist
3
Q
Carotid pulse
A
Side of trachea
4
Q
Brachial pulse
A
Side of crease of elbow
5
Q
Blood pressure
A
Measurement of force of blood as flow against wall of arteries
-healthy blood pressure: systolic 100-139 mm Hg. Diastolic 60-79 mm Hg
6
Q
Systolic pressure
A
Pressure occurs while heart is contracting
7
Q
Diastolic pressure
A
While heart is relaxed
8
Q
Electrocardiogram (ECG)
A
Determine cardiac rhythm and rate
- help diagnose electrolyte imbalance, heart attacks and other damage to heart.
- readout ECG often called ECG strips, a continuous waveform, shape corresponds to each stage of cardiac cycle
- normal heart rhythm and rate: normal sinus rhythm
9
Q
P wave
A
Right and left atrial contraction
-depolarization
10
Q
QRS complex
A
Contraction of ventricles
11
Q
T wave
A
Relaxation of ventricle
-repolarization
