Simultaneous right ventricular contraction and left ventricular fibrillation during cardiopulmonary bypass.
Two cases of brief left ventricular fibrillation concurrent with a beating right ventricle during cardiopulmonary bypass are described. Although no left or right ventricular dysfunction was detected postoperatively, this regional electrical heterogenicity suggests inhomogeneous myocardial protection during at least a short period of time. The precise mechanisms concerned are not clear and limited clinical and animal experimental analogies can be found in the literature.
