Key result
Left ventricular bypass transplants permit tolerance of severe native arrhythmias via uninterrupted donor sinus rhythm.
Case Report (n=2)
Severe arrhythmias in the native heart are well-tolerated in patients with left ventricular bypass transplants provided the donor heart maintains sinus rhythm.
Tolerability of native arrhythmias in LV bypass transplants may inform monitoring if donor sinus rhythm persists; leaves open validation in prospective cohorts.
Two patients who underwent left ventricular bypass transplants are described. Both patients sustained postoperative rhythm disturbances of their own hearts during sinus rhythm of the donor hearts. Illustrative examples of atrial flutter, ventricular flutter, ventricular fibrillation, blocked atrial extrasystoles, and double ventricular parasystole in the recipient hearts are presented. The patients tolerated all these arrhythmias well during uninterrupted sinus rhythm in the donor heart. The problems in interpretation of arrhythmias in the presence of two hearts are discussed.

Kennelly et al. (1976) conducted a case report in Postoperative arrhythmias following left ventricular bypass transplant (n=2). Left ventricular bypass transplant was evaluated on Postoperative rhythm disturbances. Two patients with left ventricular bypass transplants tolerated severe postoperative arrhythmias of their own hearts well during uninterrupted sinus rhythm in the donor hearts.
