Wide and narrow QRS complexes after arthroscopy.

A n obese (5 feet 5 inches, 224 pounds) 57-year-old woman with high blood pressure, diabetes mellitus, and arthritis underwent arthroscopy for a painful left knee. After the procedure, the electrocardiographic monitor in the recovery room showed alternately narrowing and widening QRS complexes, and a 12-lead electrocardiogram was obtained (Figure). e first three QRS complexes are wide (0.17 se...

Narrow QRS Tachycardia with Alternate Wide QRS Beats: What is the Mechanism?

A 44-year old lady underwent electrophysiology study for recurrent palpitations and documented narrow QRS regular tachycardia. The baseline ECG showed subtle preexcitation that was easily manifest on atrial pacing. The retrograde atrial activation sequence during ventricular pacing was eccentric suggesting retrograde conduction over the accessory pathway. A regular narrow QRS tachycardia with c...

Narrow QRS tachycardia to wide QRS tachycardia with LBBB morphology. What is the mechanism?

A 42-year-old woman was referred for radiofrequency catheter ablation of narrow QRS tachycardia that was terminated with intravenous adenosine. Baseline twelve-lead ECG was normal during sinus rhythm and transthoracic echocardiography demonstrated no evidence of structural heart disease. The electrophysiological study showed a normal AH interval of 114 ms and HV interval of 37 ms during sinus r...

Ventricular Tachycardia with Narrow QRS

gram. Tachyeardias originating in the left bundle branch and documented by right, left, and His bundle recordings have been produced in animals given excessive digitalis. We have noted a similar tachycardia in a patient with ischemic heart disease receiving digitalis during hypokalemia. The QRS complexes were 0.10 sec in duration and by contour suggested an ectopic focus located in the posterio...

A narrow QRS gallop rhythm

The QRS complexes 1, 2, 4, 5 and 7 are not preceded by atrial activation. The QRS morphology is slightly different from an A-V conducted beat (QRS 3, 6). Therefore an origin in the bundle branch system is presumed for beats 1, 2, 4, 5 and 7. An escape beat (QRS 2, 5) is retrogradely conducted to the atrium with atrial activation followed by AV conduction and ventricular capture (#3, 6). This ph...
