WebMay 20, 2024 · Systole and diastole are two phases of the cardiac cycle. Systolic blood pressure is when the heart contracts to pump blood out. Diastolic blood pressure is after the contraction, between heartbeats. As such, your systolic blood pressure reading will be higher. Normal Blood Pressure: Systolic: <120, Diastolic: <80. Elevated Blood Pressure ... WebDiastole is defined as the period between aortic valve closure and mitral valve closure (diastole is considered to start with the onset of relaxation of ventricular muscle contraction just proceeding the closure of the aortic valve), which consists of four phases: isovolumic relaxation, rapid filling, diastasis, and atrial systolic phases.
WebFeb 2, 2024 · Ans: The cardiac cycle is divided into two phases: diastole and systole. They happen as the heart beats, moving blood through a system of blood vessels that transports blood to all parts of the body.
