Electrocardiographically discrete right and left ventricular QRS complexes: a case report.


A patient with congestive cardiomyopathy manifested a right ventricular QRS followed after 80 msec. by a left ventricular QRS in response to a single atrial depolarization. The ventricular sequence was reversible when the left ventricle was paced directly. Virtually the entire ipsilateral ventricular ejection period occurred during diastolic filling of the… (More)
