검증된 단계별 안내1
Understand the cardiac cycle: The cardiac cycle consists of a series of events that occur in the heart during one heartbeat, including atrial contraction, ventricular contraction, atrial relaxation, and ventricular relaxation.
Identify systolic blood pressure: Systolic blood pressure is the pressure in the arteries when the heart's ventricles contract and pump blood out of the heart.
Relate systolic blood pressure to the cardiac cycle: Systolic blood pressure is specifically measured during the phase of the cardiac cycle when the ventricles are contracting.
Differentiate between the phases: Atrial contraction and relaxation occur before and after ventricular contraction, respectively. Ventricular relaxation occurs after the blood has been pumped out.
Conclude the correct event: Since systolic blood pressure is measured during ventricular contraction, this is the event of the cardiac cycle associated with the measurement of systolic blood pressure.
