Evaluation of the patient with wide QRS tachycardia
The Medical Clinics of North America
|September 1, 1984
Abstract:
Acute and long-term therapy as well as prognosis in patients with wide QRS tachycardia differ depending on the mechanism of the arrhythmia. Twelve-lead electrocardiography and prolonged electrocardiographic monitoring are often diagnostic. However, additional techniques such as esophageal and right atrial electrocardiography, or His bundle electrocardiography with detailed electrophysiologic studies, are sometimes necessary to delineate the mechanism of the arrhythmia.
