WebJan 1, 2006 · The systole duration correlated with heart rate in subjects (r = 0.79, p = 0.0003) and controls (r = 0.69, p = 0.003). In conclusion, systole is significantly prolonged and diastole correspondingly shortened in heart failure. Reversal of the normal systolic/diastolic ratio may compromise cardiac filling and function. WebIf your blood pressure is elevated—a systolic blood pressure between 120 and 129 or diastolic blood pressure of less than 80—your doctor will probably want to check it every 3-6 months.
