Lab 19 Cardiovascular physiology
Various up and down impulses produced by an ECG are called
DEFLECTION WAVES
The 2 distinct heart sounds, described phonetically as Lubb and dupp, represent
Blood turbulence associated with closing of the atrioventricular and semilunar valves.
Which of the following is NOT TRUE?
Both systolic and diastolic blood pressure can can be obtained via the pulse method.
The artery that is normal used to evaluate blood pressure is the
Brachial artery
The instrument normally used to measure blood pressure is called
Sphygmomanometer
Heart sounds provide valuable info about the
Valves.
When the semilunar valves are open during a cardiac cycle, what occurs?
1. Artioventricular valves are closed 2. Ventricles are in systole 3. Blood enters the aorta 4. Blood enters the pulmonary trunk
An average blood pressure for an adult is
120/80
An average pulse pressure is
40 mm hg
When ventricular pressure drops below atrial pressure, which phase of the cardiac cycle occurs?
ATRIAL SYSTOLE
Systole and diastole of both atria pulse systole and diastole of both ventricles is called
Cardiac cycle
The heart has an intrinsic regulating system call the cardiac_________
Conduction system
Electrical impulses accompanying the cardiac cycle are recorded by the
Electrodiograph
The period of cardiac cycle when all valves are closed and pressure continues to climb within the left ventricle is called the period of
Isovolumetric contraction
Rapping or thumping sounds heard clinically when blood pressure is being taken are called
Korot Koff sounds.
Abnormal heart sounds
Murmurs
The typical ECG produces 3 clearly recognizable waves. The first wave, which indicates depolarization of the atria is called the
P WAVE
The difference between the systolic and diastolic pressure is called
Pulse pressure
during which phase of the cardiac cycle are all four chambers in diastole?
RELAXATION PERIOD
Although pulse may be detected in most surface arteries, pulse rate is usually determined on the
Radial artery of the wrist
