Information you should know before operating the unit What are systolic and diastolic pressures? Systolic pressure is the highest pressure at the height of the heart’s contraction. Diastolic pressure is the lowest pressure when the heart is resting. What about low blood pressure? In general, a lower blood pressure reading is better un- less it causes unpleasant symptoms such as fainting and/ or lightheadedness.
Irregular heartbeat detector An irregular heartbeat is detected when a heartbeat rhythm varies while the unit is measuring the systolic and diastolic blood pressure. During each measurement, this equipment records the heartbeat intervals and works out the standard deviation. If major pulse irregularities occur, the arrhythmia icon appears on the display along with the blood pressure readings.
