The mnemonic "When you die, you relax" helps remember which cardiac phase?

• A. Diastole
• B. Systole
• C. Isovolumetric relaxation
• D. Atrial systole

Answer: (A)

The main idea is recognizing the relaxation phase of the heart, which is diastole. The phrase “When you die, you relax” links directly to relaxation, and diastole is the period when the ventricles relax after contracting and fill with blood from the atria. Systole is the contraction phase, so that wouldn’t fit with relaxation. Atrial systole is the atrial contraction portion of diastole, a specific moment within the relaxation period, but the mnemonic points to the overall relaxation phase. Isovolumetric relaxation is a brief part of diastole where the ventricles relax but all valves are closed; the mnemonic isn’t aiming at that sub-phase, just the general idea of relaxation. So diastole is the best answer.
