When analyzing a tachycardia, start by looking at three features: narrow QRS vs. wide QRS (鈮 120 ms); regular vs. irregular ventricular rate; and P waves and their relationship with QRS complexes. The differential diagnosis of a wide QRS complex tachycardia includes: Ventricular tachyarrhythmias...

The evaluation of patients presenting with wide (greater than 120 msec in duration) QRS tachycardias can be an extremely challenging problem. Diagnosing the correct mechanism of the tachycardia is necessary to properly prescribe acute and long-term therapy....

The QRS duration predicts outcomes of patients at risk for cardiac death but, alone, it is not a predictor of VT/VF events in patients undergoing standard ICD implantation. Criteria independent of QRS duration are now used to determine the appropriateness of ICD implantation in patients with or ...
Atrial burst pacing reproducibly induced two tachycardia - 1) wide QRS tachycardia with left bundle branch block (LBBB) morphology with left axis and 2) regular narrow QRS tachycardia. Figures 1A and 1B show spontaneous transition of wide QRS tachycardia to narrow QRS tachycardia. What are the ...
Narrow-QRS and Wide-QRS TachycardiasIn a woman with rheumatic heart disease, atrial flutter with a rapid ventricular response, and congestive heart failure, treatment with digoxin slows conduction in the atrioventricular node and thus allows atrioventricular conduction to occur by way of a previously ...
