“…This delay in LV activation results in less hemodynamic improvement during BiV pacing [52]. Electrical stimulation in regions of scar can also be pro-arrhythmic [53,54] and is associated with increased morbidity and mortality [8,55]. Unsurprisingly, the presence of myocardial scar at the site of LV stimulation during CRT is associated with non-response [8,56].…”

“…19---21 In 2005, Shukla et al 19 described a series of 145 consecutive patients, five of whom developed arrhythmic storm after implantation of a CRT-D, which was permanently resolved by discontinuing LV pacing. Similarly, Medina-Ravell et al 20 assessed 29 patients who received a CRT-D, four of whom developed ventricular extrasystoles with BiV pacing, eliminated when LV pacing was ended.…”

“…Na literatura, encontram-se vários relatos de aumento da incidência de arritmias ventriculares após implantação de TRC. Shukla e col, descrevem a ocorrência de TV/FV em 3,5% de doentes com TRC precocemente após implantação, resolvida com suspensão de pacing ventricular esquerdo 12 . Medina-Ravell e col, relatam um aumento marcado de extrasistoles ventriculares com R-em-T em 14% dos doentes após TRC, que foram completamente suprimidas por pacing endocárdico ventricular direito (um caso desenvolveu TV polimórfica não mantida recorrente e outro torsade de pointes incessante) 13 .…”
