Ventricular arrhythmias following left ventricular assist device implantation: a systematic review and meta-analysis of incidence and clinical impact
Authors' conclusion
Ventricular arrhythmias are frequent following LVAD implantation and are associated with a significant impact on all-cause mortality-particularly when occurring early after implantation.
