TalT:
Tall T Wave Rejection.
QRS and T waves are generated with the following values:
QRS: Rate
80 BPM
Amplitude
1 mV
Width
100 ms
T Wave Duration 180 ms
QT Interval
350 ms
T Wave Amplitude 0.0, 0.2, 0.4, 0.6, 0.8, 1.0, and 1.2 mV .
In the automatic test sequence the T Wave Amplitude steps through the changes at one minute
intervals. The display indicates the T Wave Amplitude and the QRS Rate.
As the T wave amplitude increases, the first value at which the patient monitor counts the T wave at 80
±
8 BPM should be noted. This value should match the patient monitor manufacturer’s specification.
PPR: Pacemaker Pulse Rejection.
The test sequence cycles through normal paced rhythm (AP),
ineffective pacing (Asynchronous Pacing ASP), and pacemaker pulses alone (PCR).
For normal pacing (AP),QRS and pacer waves are generated with the following values:
QRS: Amplitude 1 mV
Width
100 ms
T wave: Amplitude 0.2 mV
Duration 180 ms
Q-T Interval
350 ms
R-R Interval
1 Sec
Pacer: Amplitude 2 mV, -2 mV
Width
2 ms, 0.1 ms
For ineffective pacing (ASP), the values of the QRS and pacer waves are the same as normal pacing
except for the QRS rate that becomes 30 BPM and the pacer rate that becomes 80 BPM.
During the ASP and AP test sequences the display will show the pacer amplitude, the pacer width, and
the QRS rate.
For pacemaker pulses alone (PCR) the values generated are:
Pacer: Rate
60 BPM
Width 2.0 ms, 0.1 ms
Amplitude 2 mV, -2 mV
During the PCR test sequence the display will show the pacer amplitude, the pacer width, and the QRS
rate.
Each set of values in the test sequence is generated and displayed for 20 seconds.
TAC:
Time to Alarm for Tachycardia.
The TAC test is designed to measure the time it takes for the
patient monitor to alarm after the onset of ventricular tachycardia. The low and high alarms on the
patient monitor should be set at 60 BPM 100 BPM before starting the test.
This auto test sequence generates a QRS wave form at the rate of 80 BPM alternating with a ventricular
tachycardia waveform with rates of 206 and 195 BPM and amplitudes of 1.0, 0.5, 2.0, and 4.0 mV.
Each waveform is generated for 20 seconds and the display will show the amplitude and the rate of the
waveform being generated.
The following is the sequence of waveforms:
