Question

What is total diastolic time of ventricle in cardiac cycle?

• A. 0.30 second
• B. 0.40 second
• C. 0.50 second
• D. 0.10 second

Answer 1

The correct option is C 0.50 second

Cardiac cycle is the sequence of events that happens during one heart beat. Duration of one cardiac cycle is 0.8 sec. It is divided into two phases, namely diastole and systole. During systole, contraction of ventricle takes place and blood leaves the heart. During diastole, the heart is relaxed and is filled with blood. Total systolic and diastolic time of atrial cycle is 0.1 second and 0.7 second respectively. Similarly, total systolic and diastolic time of ventricle in cardiac cycle is 0.3 second and 0.5 second.

Thus, the correct answer is option C.
