Primer implante de electrodo de estimulación selectiva del haz de His en Colombia: Reporte de dos casos

pacing in the right ventricular apex is known to produce ventricular dysynchrony and patients often develop dilated cardiomiopathy. for this reason, a more physiological stimulation has been performed. with the recent technological development of electrodes for selective stimulation of the his bundle, we want to show the experience of this type of implantation in the first two cases made in the electrophysiology laboratory in medellin.
