Systole is the contraction of the heart while diastole refers to the relaxation part. These terms can refer to only one area of the heart, but they mostly refer to ventricular action. When we take someone’s blood pressure, the numbers that are found are systole / diastole, which is important because it can indicate the status of the heart.
