The continuity detection apparatus continuously monitors continuity between two EKG electrodes contacting the patient and inhibits the system from its measuring of heartbeat intervals whenever poor continuity is detected. This eliminates the effects on the system of any undetected heartbeats or heartbeat artifacts of the type caused by poor continuity, and thereby improves the accuracy of the system's heartbeat rate estimate.Field of SearchPATIENT PROTECTION FROM ELECTRIC SHOCK | |
