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

Article information

Se conoce que la estimulación en el ápex del ventrículo derecho produce disincronía ventricular y muchas veces los pacientes desarrollan miocardiopatía dilatada, lo que ha llevado a realizar una estimulación más fisiológica. Con el reciente desarrollo tecnológico de los electrodos para la estimulación selectiva del haz de His (fisiológica), se quiere mostrar la experiencia en el implante de este tipo de electrodos en los dos primeros casos del servicio de electrofisiología de la Clínica Medellín.

Palabras clave:

estimulación fisiológica

select site

haz de His

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.

Key words:

physiological stimulation

select site

bundle of His
