Meaning and Clinical Context

The phase of the cardiac cycle during which the heart muscle contracts, ejecting blood from the ventricles into the aorta and pulmonary artery.

Systole is clinically assessed by the first heart sound (S1) and correlates with the QRS complex on ECG; impaired systolic function is a hallmark of heart failure with reduced ejection fraction.

Turkish Translation

Sistol

Example in Use

English: During systole, the left ventricular pressure exceeds aortic pressure, causing the aortic valve to open and eject oxygenated blood into systemic circulation.

Turkish: Sistol sırasında, sol ventrikül basıncı aort basıncını aşar, bu da aort kapağının açılmasına ve oksijenli kanın sistemik dolaşıma atılmasına neden olur.

Clinical Notes

Scenario

A 58-year-old male with ischemic cardiomyopathy presents with fatigue; echocardiogram shows global hypokinesis with prolonged systolic duration.

Response Template

The patient's systolic function is severely reduced with an LVEF of 30%; initiate guideline-directed medical therapy for HFrEF.
