For PACE pulses that meet the criteria below, PAEC will be marked on
the screen:
Detection range: ± 4mv ~ ± 700mv
Pulse width: 0.2ms ~ 2.0ms
Calculate from 15s data
Calculate once every second
Time from 80bpm to 120bpm: ≤ 10sec
Time from 80bpm to 40bpm: ≤ 10sec
For T-wave with 100ms QRS wave, 350ms QT period, 180ms duration
and 1.2mV amplitude, the HR calculation won't be affected
