Abstract
Wide QRS complex tachycardia is a common clinical occurrence and presents a diagnostic challenge for the physician. History, physical examination, chest radiographs, and electrocardiographic analysis are important in making the correct diagnosis. Diagnosis of ventricular tachycardia is supported by history of prior myocardial infarction or congestive heart failure, physical examination showing cannon A-waves in the jugular venous pulsation or variable heart sounds, chest radiograph showing cardiomegaly or evidence of prior cardiac surgery, and characteristic ECG features: AV dissociation, fusion/capture beats, QRS concordance or typical morphologic features in leads V1 and V6. In this article, a clinical approach to wide QRS complex tachycardias is presented.
