A100 ms
B270 ms
C430 ms
D1000 ms
Answer & Solution
Correct answer: C. 430 ms
1. Ventricular relaxation follows repolarisation, shown by the T wave.
2. It also divides into two distinct phases and lasts approximately 430 ms.
3. That makes diastole the longest single stretch of the cardiac cycle at rest.
