ABSTRACT
We report a case of temporary synchronous ventricular pacing in a patient after complete CRT-D system removal due to lead-related infective endocarditis. The patient was stimulation-dependent because of complete heart block and ventricular dyssynchrony. Basing on an ECG which showed sinus rhythm, we used a Medtronic SEDR01 Sensia DR pacemaker with Biotronik Linox Smart S DX PRO MRI 65/15 lead. The DX ICD leads have a floating sensing atrial dipole which enables synchronous ventricular pacing without implantation of an atrial lead. Device control showed that the measured P-wave amplitude of 0,35 - 0,5 mV was sufficient for atrial sensing. Our case proves it is possible to use a DX lead connected to a VDD pacemaker in order to provide atrioventricular synchrony (AsVp = 99,9%).
