Bundle branch reentry VT with right and left bundle branch block (BBB) patterns was induced in 1 and 9 patients, respectively. The right bundle was attempted to record by a 6F decapolar or quadripolar catheter. Electroanatomic mapping of the left ventricle was performed in 6 patients. In all left BBB pattern VT, the mean VT cycle length was 329.3\u00b189.1 ms, and the median HV interval during tachycardia was longer than that of baseline (78 [73\u2013100] versus 71 [64.5\u201388] ms;\n              <jats:italic>P<\/jats:italic>\n              =0.11).\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results:<\/jats:title>\n            <jats:p>\n              The H-RB interval during VT was slightly shorter (\n              <jats:italic>P<\/jats:italic>\n              =0.14); however, the median RB-V interval was markedly longer than that during sinus rhythm (50 [29.5\u201383] versus 30 [8\u201351] ms;\n              <jats:italic>P<\/jats:italic>\n              =0.043]. In 6 patients with 3-dimensional mapping of the left ventricle, a slow anterograde or retrograde conduction over left HIS-Purkinje system with normal myocardial voltage was identified. In addition, Purkinje-related VTs (1.0\u00b11.3 types) were also induced in 5 patients. Ablation was applied in distal left BB in patients with baseline left BBB and in one narrow QRS patient with sustained Purkinje-related VT, whereas right BB was targeted in other patients. During a mean follow-up of 31.4 months, frequent premature ventricular contractions occurred in one patient, and new VT developed in the other patient.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions:<\/jats:title>\n            <jats:p>Bundle branch reentry VT can occur in young patients with extensive conduction disturbances within HIS-Purkinje system.
