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
