Systolinen

Systolinen is a Finnish adjective meaning related to systole, the phase of the heartbeat during which the heart muscle contracts to pump blood. In medical Finnish, systolinen is used to describe processes, measurements, and functions connected to systole. The English equivalent is systolic, and diastolic corresponds to diastolinen in Finnish.

Overview of systole: The cardiac cycle consists of systole and diastole. Atrial systole occurs when the atria contract, while ventricular systole is the contraction of the ventricles that ejects blood into the aorta and pulmonary artery. The systolic phase corresponds to the highest arterial pressure in the arteries.

Typical usage: The term appears in phrases such as systolinen verenpaine (systolic blood pressure) and systolinen toiminta (systolic function). In cardiology, tests and imaging evaluate systolic function, for example by measuring the ejection fraction during systole. Systolic murmurs are heart murmurs heard during the systolic phase.

Clinical relevance and ranges: Systolic values are used to assess cardiovascular health. A resting systolic pressure around 90–120 mmHg is often cited as normal for adults, though ranges vary with age and context. Hypertension, hypotension, or reduced systolic function can indicate health problems. Isolated systolic hypertension, common in older adults, arises from arterial stiffness and affects cardiovascular risk.
