A widened QRS duration occurs in the setting of a right bundle branch block, left bundle branch block, non-specific intraventricular conduction delay and during ventricular arrhythmias such as ...

Additional ECGs showed a wide-QRS-complex rhythm of uncertain mechanism. A bedside cardiac ultrasound examination showed diffuse global hypokinesis of the left ventricle. Table 1.

The QRS complex duration is increased ... Hence, the widened QRS complex is the result of an intraventricular conduction delay (IVCD) and not a LBBB. In contrast to a LBBB, ...

A simple way to diagnose a left bundle branch in an ECG with a widened QRS complex (> 120 ms) would be to look at lead V1. If the QRS complex is widened and downwardly deflected in lead V1, a left ...

LV dyssynchrony is most prevalent among patients with wide QRS intervals, but patients with narrow complexes still exhibit LV dyssynchrony as quantified by tissue Doppler imaging. On the basis of ...

Among patients with a reduced ejection fraction, a widened QRS complex, and NYHA class II or III heart failure, the survival benefit associated with receipt of a CRT-D as compared with ICD ...

The wide QRS complex tachycardias terminated with retrograde P waves after the fourth and 12th QRS complexes, Jhawar and co-authors said.

Eligible heart failure patients with a wide QRS complex spent more time alive after use of a cardiac resynchronization therapy defibrillator (CRT-D) compared with an implantable cardioverter ...

Wide QRS complex is a frequently diagnosed ECG abnormality among patients with severe heart failure, 8 which also proved to be a predictor of mortality in this patient population. 29 The wide QRS ...
