Pacemaker detection

The settings for pacemaker detection can be changed during the ECG acquisition.

To change pacemaker detection:

1. Open Settings | Pacemaker detection...

2. Select the electrodes to be used for the detection.

3. Select whether the pacemaker should be replaced with 1 mV impulse.

Pacemaker impulses

Impulses delivered by pacemakers can be so narrow that it is not possible to display the

original pulse. Therefore, the system shows a synthetic impulse exactly at the point of the

ECG where the original impulse was detected.

The synthetic impulse is displayed on all channels and always with positive polarity.

Figure 3-5: Example of pacemaker impulses

The level of the synthetic impulse is 1 mV. By default, the width of the synthetic impulse

is set to 8 ms.
