Cardiac arrhythmias has been frequently reported after left ventricular assist devices implantation but currently literature shows no sufficient information on cardiac arrhythmias. Objective: The aim of this study was to assess the frequency and other features of ventricular and supra ventricular ectopic beats ((SVEB), atrial fibrillation (AF)/flutter (AFL) post device implantation. Methods:This is a retrospective study conducted in Department of Cardiac-Surgery, University of Verona Medical School, Verona, Italy from June 2014-September 2016. Rhythm monitoring and registration were collected from 16 patients (13 males; 45±13years) during the first five (05) days after implantation. To assess late post-operative rhythm, patient’s hospital electronic records were used as well asfunctional hemodynamic parameters including mean arterial pressure(MAP), right atrial pressure(RAP), heart rate(HR) and ST-deviation(d-ST). Results: Ventricular arrhythmia (n=9), atrial fibrillation (n=5) or atrial flutter (n=2) episodes were preoperatively present in 11 patients. Postoperatively, 5 patients developed either VT (n=2), AF (n=1) or both VT/AF (n=2) during a follow-up of 18±14 months. Prior to postoperative VT (POVT) episodes (n=123), MAP decreased, HR, d-ST increased and RAP remained unaltered. POVT were initiated either by single VEBS (28%), V-couplets (15%), V-run (46%) or occurred suddenly (11%).Conclusions: Ventricular and supraventricular arrhythmias are common after device implantation. The frequency of sustained VTA was less at early phase as compared to late postoperative phase.
