Systolic blood pressure

Systolic blood pressure is the highest blood pressure reached at a given point during a heart cycle. When recording blood pressure e.g. 120/80 mmHg, the systolic pressure is always given before the slash. Systolic blood pressure should not exceed 140 mmHg in a healthy adult.
