Of these 13 patients (<jats:styled-content>9 men and 4 women; mean age 64 \u00b1 13 years<\/jats:styled-content>), 6 had an HV interval \u226455 msec (group A), and 7 had a prolonged HV interval (&gt;55 msec; group B) during sinus rhythm (SR). PR interval (<jats:styled-content>169 \u00b1 32 vs 339 \u00b1 138 msec, P = 0.01<\/jats:styled-content>) and QRS duration (<jats:styled-content>116 \u00b1 17 vs 167 \u00b1 29 msec, P = 0.003<\/jats:styled-content>) during SR were significantly shorter in group A than in group B. In group A, the HV interval was significantly longer during VT than during SR (<jats:styled-content>73 \u00b1 18 vs 47 \u00b1 7 msec, P = 0.007<\/jats:styled-content>). There were more patients with functional His\u2010Purkinje block (split His potentials, a jump of HV interval induced by programmed atrial stimulation or burst pacing) or phase 3 block in group A than group B (<jats:styled-content>6\/6 patients vs 0\/7 patients, P &lt; 0.001<\/jats:styled-content>). Successful ablation of the right bundle branch was performed in all 13 patients without deteriorating AV block. Two patients died in each group, and VTs (other than BBRT) or ventricular fibrillation were documented by ICD electrogram storages in 4 patients during follow\u2010up of <jats:styled-content>27 \u00b1 17<\/jats:styled-content> months.<\/jats:p><jats:p> <jats:italic>Conclusion:<\/jats:italic> A prolonged HV interval during SR is not a prerequisite for BBRT.
