The present patient demonstrated torsade de pointes (TdP) after a pacemaker implantation without a decrease in heart rate or pacemaker malfunction. Marked QT prolongation and TdP were closely related to alteration of the depolarization pattern (appearance of junctional rhythm). Resetting the pacemaker to a rate that inhibited spontaneous rhythm was effective in preventing TdP.
该患者在起搏器植入后出现尖端扭转型室速（TdP），心率未降低且起搏器无故障。明显的QT间期延长和TdP与去极化模式改变（交界性心律的出现）密切相关。将起搏器重置为抑制自发心律的频率可有效预防TdP。
