Different QRS morphologies in a dual-chamber pacemaker: what is the mechanism?

Oswaldo Gutiérrez1.   

Abstract

A 12-lead electrocardiogram (ECG) of a dual-chamber pacemaker with different paced QRS morphologies is presented. Such an observation is usually made when there are different degrees of fusion, in association with the intrinsic rhythm in the presence of spontaneous changes of the stimulation mode of the pacemaker.
