Which wave of ECG is associated with isovolumetric relaxation change the beat?
A
True
B
False
Answer
False
Explanation
Solution
Isovolumetric relaxation is a phase of ventricular diastole where ventricles relax, and all valves are closed, causing constant ventricular volume while pressure drops. This phase occurs after the T wave on an ECG. ECG waves (P, QRS, T) represent electrical depolarization and repolarization. There is no specific ECG wave that corresponds to the mechanical event of isovolumetric relaxation. Hence, the statement implying such an association is false.
