132 Technical data Welch Allyn 1500 Patient Monitor
Respiration
Temperature
ECG amplifier
Sampling frequency 1000 Hz
Pacemaker detection ± 2 to ± 700 mV / 0.1 to 2 ms
Pacemaker rejection ± 2 to ± 700 mV / 0.1 to 2 ms
Note: Pacemaker signals can differ from one pacemaker to the next. Rate
meters may continue to count the pacemaker rate during occurrences of
cardiac arrest or some arrhythmias, mainly with pacemakers generating
high amplitudes ( > 20 mV) or those generating overshoot. Pacemaker
patients should be kept under close or constant observation.
