Relationship of echocardiographic left ventricular dyssynchrony with QRS width on surface electrocardiogram in patients with systolic heart failure: An observational study

This study aimed to evaluate left ventricular dyssynchrony with QRS width on ECG in patients with systolic heart failure. 100 study patients were classified into two groups. Narrow QRS group-N- QRS (80-119 msec) and Wide QRS group-W- QRS (120-160 msec). Out of each 50 patients in W- QRS group, 38(76...

Sumario:This study aimed to evaluate left ventricular dyssynchrony with QRS width on ECG in patients with systolic heart failure. 100 study patients were classified into two groups. Narrow QRS group-N- QRS (80-119 msec) and Wide QRS group-W- QRS (120-160 msec). Out of each 50 patients in W- QRS group, 38(76%) had LV dyssynchrony and 18 (36%) in N- QRS group had ventricular dyssynchrony. Dyssynchrony in narrow QRS patients with heart failure also needs attention as a therapeutic target in future studies.
