1. The time between each heart beat is called:

a. interval

b. strength

C. systole

d. diastole

. In general, as the interval between each heart beat
increases the strength of ventricular contraction:

a. increases

b. decreases

C. vanes

d. cannot be predicted

The systolic contraction following a premature ventricular
contraction with a compensatory pause will be:

a. increased

b. decreased

c. unchanged

d. cannot be predicted

The phenonmenon where there is an increase in systolic
contraction following a premature ventricular contraction with a compensatory
pause is called:

a. pressure half time

b. interval-strength

c. systole

d. diastole

. According to the interval-strength relationship, the peak
velocity and peak pressure gradient post premature ventricular contraction with
a compensatory pause will be:

a. increased

b. decreased

c. unchanged

d. cannot be predicted

According to the interval-strength relationship, the
strength of ventricular contraction in a patient with sinus bradycardia will
be:

a. increased

b. decreased

c. unchanged

d. cannot be predicted
