Abstract:
This article reports on practical problems and possible solutions that may occur in case of upgrading a dual-chamber pacemaker by implanting a second left ventricular ventricular pacing, ventricular sensing, ventricular triggering (VVT) pacemaker. This therapeutic strategy was considered appropriate in the case of a 73-year-old patient with severe heart failure, who was scheduled to undergo coronary artery bypass surgery. A right-sided, dual-chamber pacemaker had been already implanted to the patient. The duration of the paced QRS complex was 220 ms and inter- and intraventricular dyssynchrony was documented in the echocardiographic study. We describe the methodological problems and possible solutions related to biventricular pacing following the abovementioned strategy.
