Pacemaker Rejection per EC13:1992 Clause 3.1.4.1 Rejects all specified pacemaker signals, including
double paces, without over/undershoot.
Exception: Ineffectively paced QRS pattern may
cause a QRS to be rejected and not counted as a
pulse when the pace occurs very close to the R
wave.
Pacemaker Rejection per EC13:1992 Clause 3.1.4.2 Rejects all specified pacemaker signals, including
double paces, with over/undershoot with the
exception of ±2 mV amplitude, 0.1 ms duration, 0.5
mV overshoot, time constant=100
