High-resolution electrocardiography in dogs under doxorubicin-induced cardiomyopathy
The occurrence of late potentials in dogs under doxorubicin-induced cardiomyopathy and their relationship with the development of ventricular arrhythmias or sudden death were studied. Seven adult mongrel dogs of both sexes were used. Cardiomyopathy was induced by slow intravenous infusion of doxorubicin (30mg/m²) at 21-day intervals, until a total cumulative dose of 240mg/m² was reached. Animals were monitored by echocardiography. After the induction of cardiomyopathy, high-resolution electrocardiography was recorded. Late potentials were observed in two animals that suddenly died a few days later.
