ABSTRACT

The most important clinical characteristic of paroxysmal tachycardias is that they start and finish with no evident cause. This makes the difficult to record during the episode and, as a consequence, hard to diagnose and treat. The electrophysiological studies of the last 7 years (2003-2009) were analyzed. According to the diagnosis they were grouped into atrial, reciprocal and ventricular tachycardias. A total of 841 both diagnostic and therapeutic studies were accomplished. 73.6% of the patients had some form of paroxysmal tachycardia. The mean age was 42.2 and 52.6% were male. The palpitation crises started at the age of 26 on average, and their mean duration was from 9 to 50 min (between 20 minutes and 48 hours). The clinical-electrocardiographic diagnosis was: supraventricular tachycardias without preexcitation 45%, preexcitation syndrome (W-P-W) 26%, ventricular tachycardia (VT) 10%, atrial flutter 7.5%, paroxysmal atrial fibrillation 6.5, and 5% with atrial tachycardia. The certainty electrophysiological diagnoses were: nodal reentrant tachycardia 18%, left hidden bundle of Kent 16%, right Kent (W-P-W) 16%, left Kent (W-P-W) 15%, atrial flutter 13.6%, atrial tachycardia 10%. Among ventricular tachycardias, paroxysmal atrial fibrillation, right Kent and the rest were bundle of Mahaim. Ablations as healing treatment were overall successful in 86.4% of the cases with 12.2% relapse. The LocaLisa system was used as electroanatomic cartograph in 153 cases. Eighty seven transeptal atrial punctures. The accidental AV block occurred in only 4 cases, and in 2 more there was temporary supra-His-AV block.
