Heart Rate Meter; Configuring Heart Rate (Hr) Meter Alarms - ZOLL M2 Operator's Manual

Heart Rate Meter

The Heart Rate meter displays the QRS complex rate that it derives from the ECG monitoring
function. The Heart Rate meter always computes the heart rate from the top waveform. The
Heart Rate meter is labeled HR (as in the following example) if the source is ECG, and PR if
SPO2 is measured and ECG cable is disconnected.

The ZOLL M2 unit allows you to enable and disable the Heart Rate (HR) alarm, to set alarm
limits, and to select a QRS detection tone volume. The default HR alarm settings (enable/
disable, alarm limits) are supervisor configurable.
