Heart Rate Alarm Limits
Alarms occurring during the process of ECG measurement include two (2) types:
physiological alarms and technical alarms. Physiological alarms occur when the patient’s
heart rate value is equal to or exceeds set alarm limits. Technical alarms are any ECG-related
alarms, which are not physiological, such as functional failures.
