Directions for Use Specifications 145
Pacer pulse rejection Does not count as heartbeats approximately 95% of pacemaker pulses within pacer
pulse detection range*, with or without AAMI (EC 13
- 2002) tails of 4, 8, 15, 25, 50, 75,
or 100 ms decay time constant, whose tail amplitudes meet either EC 13’s method A or
method B criteria for single pacer pulses, or A
- V sequential pulses (150 ms and 250 ms
separation), all per AAMI tests 4.1.4.1 and 4.1.4.2.
* Rejects method B overshoots for [pulse width] X [pulse amplitude] < 3 X 10
-4 V-sec.
Pacer pulse detector minimum
slew rate detection threshold 2.5 V/sec RTI, per EC13:2002, 4.1.4.3
ECG trace duration 3 seconds in single or double trace display
6 seconds in cascade

Ventricular bigeminy (VB) 78 to 82 beats/min (80 beats/min expected)
Slow alternating VB 57 to 65 beats/min (60 beats/min expected)
Rapid alternating VB 118 to 123 beats/min (120 beats/min expected)
Bidirectional systole 88 to 93 beats/min (90 beats/min expected)
1 mV ventricular tachycardia 197 to 198 beats/min (206 beats/min expected)
2 mV ventricular tachycardia 193 to 197 beats/min (195 beats/min expected)
