Relearning Monitoring ECG

7 - 34 TM80/TM70 Telemetry Monitor Operator’s Manual

7.9.4 Understanding the Arrhythmia Display

The arrhythmia l area displays:

1. Parameter label

2. PVCs per minute label

3. PVCs per minute value

4. Pauses per minute label

5. Pauses per minute value

7.10 Relearning

Changes in ECG template could result in incorrect arrhythmia alarms and/or inaccurate

heart rate.

ECG relearning allows the TM80/TM70 to learn new ECG template so as to correct

arrhythmia alarms and HR value. Once learning is complete, the dominant QRS complex

is stored as a reference template. The reference template is used as a normal morphol-

ogy of that patient and it is compared with incoming beats to identify possible arrhyth-

mias.

7.10.1 Automatically Initiating an ECG Relearning

Auto arrhythmia relearning is initiated in the following situation:

■ TM80/TM70 power-up

■ Return to normal monitoring from the Standby mode

■ Enabling ST or Arrhythmia analysis

■ The lead has been changed in ECG 1 waveform (3 lead only)

■ Patient size changes

NOTE

• ST Analysis must be turned on before it will relearn.
