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.
本研究旨在评估心电图 QRS 宽度与收缩性心力衰竭患者左心室不同步的关系。100 例研究患者被分为两组。窄 QRS 组（N- QRS：80-119msec）和宽 QRS 组（W- QRS：120-160msec）。在 W- QRS 组的 50 例患者中，38 例（76%）存在左心室不同步，而 N- QRS 组的 18 例（36%）患者存在心室不同步。未来的研究也需要关注心力衰竭时窄 QRS 患者的不同步现象，并将其作为治疗靶点。
