A kutatási téma leírása:
One of the most frequent cardiac operations is the valve implantation due to valvular dysfunction. Since the close vicinity of the annulus and the conduction system, approximately 3-12% of operated patient needs permanent pacemaker implantation postoperatively.
Signal-averaged technique facilitates the high-resolution surface-ECG registration, and the improved signal-to-noise ratio makes possible capturing ventricular late potentials or His-electrogram. By the invasive His-ECG benign (proximal) and malignant (distal) AV-block can be differentiated, which latter one indicates permanent pacemaker implantation.
The aim of present investigation is the analysis of pre- and early postoperative non-invasive electrophysiological examination focused on the conduction system, especially the His-potential. The non-invasive electrophysiological parameters and their borderline values will be defined after the follow-up, which expectedly supports the prediction of reversibility of the perioperative conduction disturbance, facilitating the correct indication of permanent pacemaker implantation.
