2.11.3 Real-time IEGM Transmission
The pulse generators provide real time transmission of the
unfiltered intracardiac electrogram (IEGM) to the programmer.
IEGMs from the atrium and ventricles can be simultaneously
recorded with a bandwidth of 0.5 to 200 Hz. Depending on the
device, the following channels are simultaneously recorded:
•
During single chamber (VR / VR-T) operation, far field,
and RV electrograms are available.
•
During dual chamber (DR / DR-T) operation, far field, RA,
and RV electrograms are available.
•
During triple chamber (HF / HF-T) operation, RA, and RV,
LV electrograms are available.
The IEGMs may be transmitted to the programmer via the
programming head positioned over the implanted pulse generator.
The surface ECG is continuously displayed in the Overview
screen, the Sensing screen and the EP test functions module.
Real-time IEGMs are available in the EP tests and sensing /
impedance screens. They are then displayed together with
surface ECG and markers on the programmer screen and printed
on the ECG recorder. Likewise, intracardiac signals and markers
identifying atrial/ventricular paced and sensed events are
received via the programming head, and may be displayed on the
programmer screen and printed on the ECG recorder.
To determine the amplitudes of intracardiac signals (P-/R-waves)
the automatic P/R-wave measurement function may be used.
Please refer to the appropriate software technical manual for a
description of marker signal operation.
