ECG Patient Cable
Disconnection Safety
All ECG connections are patient safe within 750
msec of patient cable removal, with patient leakage
current <10  Exception: Leadset detection pins
are protected mechanically to prevent patient
contact.

Heart Rate Averaging Method
Two different methods are used:
 Normally, heart rate is computed by averaging the 12
most recent RR intervals.
 If each of 3 consecutive RR intervals are greater than
1200 milliseconds (i.e. rate less than 50 b/min) for adult
and pediatric patients, then the 4 most recent RR
intervals are averaged to compute the HR.
Heart Rate Meter Accuracy and Response
to Irregular Rhythm
Provides correct heart rates (80, 60, 120, 90 b/min) using
test waveforms as indicated in ANSI/AAMI EC13
Sec. 4. 1. 2. 1 (e).
Response Time of Heart Rate Meter to
Change in Heart Rate
For a rate increase, the average time to reach the specified
heart rate using test waveforms as indicated in ANSI/AAMI
EC13 Sec. 4. 1. 2. 1 (f) is 10 seconds. For a rate drop, the
average time is 7 seconds.
