Case ReportsArrhythmias in two patients with left ventricular bypass transplants.
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. ⋯ 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.

Case ReportsEchocardiographic findings after acute carbon monoxide poisoning.
Myocardial lesions are frequently seen at necropsy after fatal carbon monoxide poisoning. Clinically, while there have been numerous reports of chest pain and electrocardiographic changes associated with acute carbon monoxide poisoning, other evidence for left ventricular abnormality has not been reported. The echocardiographic findings in five cases of non-fatal poisoning are presented here. ⋯ Motion returned to normal in 2 of the 3 in follow-up tracings. Echocardiograms on 3 of the 5 patients showed mitral valve prolapse. Though the mitral valve prolapse may have been present before the poisoning, the reported high incidence of papillary muscle lesions in fatal cases suggests a possible relation of the prolapse to the effects of the carbon monoxide poisoning.
