Pacing pulse
Pulse identification
For PACE MAKER pulses that meet the criteria below, pacing pulse will be marked
on the screen.
Detection range(Amplitude): ± 2 mV ~ ± 700 mV
Pulse width: 0.2ms ~ 2.0 ms
Average HR
Calculate from 15s data
Interval of HR refreshing
Calculate once every second
HR change response time
Time from 80 bpm to 120 bpm:
≤
10 sec
Time from 80 bpm to 40 bpm:
≤
10 sec
Tall T-wave suppression
For T-wave with 100ms QRS wave, 350ms QT period, 180ms duration and 1.2mV
amplitude, the HR calculation will not be affected
Without overshoot rejection of
pacemaker pulses
Amplitudes (ap) from ±2 mV to ±700 mV and pulse widths from 0.1 ms to 2.0 ms.
