"Evaluation of Non-invasive Measurement of Electrophysiological HV Interval Using a High-density and High-fidelity Signal Averaging ECG 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.
