TELEMETRY TRANSMITTER (96281) OPERATIONS MANUAL 3-14
The on-transmitter heart rate display has been tested according to IEC 60601-2-27:2011 for:
Tall T-wave rejection: It rejects T-waves up to 150% of the QRS complex amplitude,
Maximum response times, to the nearest second, to step changes in heart rates:
- 5 seconds when the heart rate changes from 80 beats per minute to 120 beats per minute.
- 5 seconds when the heart rate changes from 80 beats per minute to 40 beats per minute.
Heart rate accuracy and response to irregular rhythms:
The heart rates that show on the display for the four irregular rhythm test waveforms within the
standard are listed in
Table 4.
Warning:
The on-transmitter heart rate display accuracy may be affected by cardiac arrhythmias
and pacemaker pulses. The heart rate shown on a central station or bedside monitor
may similarly be affected. Refer to their manuals for appropriate details.
Note:
The on-transmitter heart rate is calculated using ECG Lead II only, consequently if either RA or
LL electrode is not present, then heart rate cannot be calculated and
??? will be shown on the
transmitter display.
