UNLABELLED: Aim of the study was analysis of electrophysiological and clinical parameters related to increasement of recurrence risk of AVNRT and subjective heart feelings after successful RF ablation.
MATERIALS AND METHODS: Retrospective analysis was made among patients after successful RF AVNRT ablation. Study group was 93 patients (F=63), mean age 46.7+15.9 (from 18 to 80y). Electrophysiological and physical parameters achieved during electrophysiological study was analysed. Using telephone monitoring and question survey patients were divided into 3 subgroups A – without symptoms, B – with subjective arrhythmia feelings and C with documented arrhythmia recurrence.
RESULTS: 6.4% patients (n=6) had documented arrhythmia recurrence AVNRT (subgroup C); women 100% (n=6), mean age 43.5±14 years. 43% of patients (n=40) after successful RF ablation had subjective feelings of heart palpitations of a different kind (subgroup B); women 68% (n=32), mean age 42.8±14 years. 51% (n=47) of patients didn’t feel any arrhythmia (subgroup A); women 64% (n=36), mean age 50.7±17 years.
CONCLUSIONS: Factors related to increased risk of arrhythmia recurrence was: atypical forms of tachycardia, shorter tachycardia cycle, slow pathway modification, low mean power during RF ablation. Among patients without documented arrhythmia recurrence: lower age, higher time from the beginning arrhythmia until ablation procedure and Wenckebach Point cycle length shorter predispose to inadequate subjective arrhythmia feelings after successful RF ablation.
