    Korotkoff sounds: The audible sounds of blood pressure named after Dr. Korotkoff who discovered them.

    Orthostatic hypotension: A decrease in blood pressure by at least 20 mmHg systolic or 10 mmHg diastolic within three minutes of standing from a seated or lying position.

    Sphygmomanometer: A device used to measure blood pressure and is commonly referred to as a blood pressure cuff.

    Systole: The phase of the heartbeat when the left ventricle contracts and pumps blood into the arteries.

    Systolic blood pressure: The maximum pressure of blood on the arteries during the contraction of the left ventricle of the heart referred to as systole.
