(TdP, meaning "twisting of the points") is a polymorphic ventricular tachycardia (VT) characterized by twisting QRS complexes around the isoelectric line, typically associated with prolonged QT intervals from congenital or acquired causes. A 64-year-old woman with hypertension presented with recurrent syncope and bradycardia. A 12-lead electrocardiogram (ECG) revealed a 2:1 atrioventricular block (AVB) and a prolonged corrected QT (cQT) interval (544 ms). Holter monitoring showed repeated episodes of TdP correlating with her symptoms. This case underscores prompt recognition and treatment to prevent sudden cardiac death - in this case, by electrolyte modulation.
尖端扭转型室性心动过速(TdP,意为“尖端扭转”)是一种多形性室性心动过速(VT),其特征为QRS波群围绕等电线扭转,通常与先天性或后天性原因导致的QT间期延长有关。一名64岁高血压女性患者出现反复晕厥和心动过缓。12导联心电图(ECG)显示二度房室传导阻滞(AVB)和校正QT(cQT)间期延长(544毫秒)。动态心电图监测显示反复出现与她症状相关的TdP发作。该病例强调了为预防心源性猝死而进行及时识别和治疗的重要性——在本病例中,通过调节电解质来实现。
