His-Ventricle (HV) measurement is only obtained invasively using transvenous catheters. This kind of procedure is routinely performed but some risks of complication exist. HV interval prolongation is correlated with increased risk of occurrence of complete atrioventricular block which could lead to syncope or cardiac sudden death. A new non invasive, high density and high fidelity system (BioSemi, BioSemi B.V., Amsterdam, Netherlands) can theorically collect such electrophysiological signal using a signal averaging acquisition method. We want to assess the possibility of non invasive HV interval measurement using this new device.

Electrophysiological exploration is performed, as part of the routine care, after the Biosemi high density ECG, the same day or maximum 4 days later. It is performed in interventional rhythmology room, under fluoroscopic control. After local anesthesia, one or more introducers are placed in the femoral vein allowing the introduction of catheters. These catheters allow recording of the HV interval
Non invasive ECG monitoring for HV measurement using high density Biosemi device. This device use 256 skin electrodes. At the same time and with the same system, a chest pressure sensor can record the patient's breathing movements.
