心脏性猝死的预警标志

Warning signs of sudden cardiac death

心脏性猝死(SCD)是指由各种心脏原因引起的,出现急性症状1h内发生的突然死亡。我国每年发生SCD人数约54.4万。除了植入ICD以外,目前尚无任何药物可以预防其发生。QT间期离散度、QRS-T夹角、Osborn波及Lambda波、心率震荡、T波电交替等SCD预警因子不断涌现。本文将就此分类讨论。

Sudden cardiac death（SCD）is resulted from a variety of cardiac causes,characterised by abrupt loss of consciousness within one hour of the onset of acute symptoms.In China,there are about 544,000 people suffered from SCD each year.Except from ICD implantation,there are no drugs which can prevent SCD.SCD warning signs,like QT interval dispersion,QRS-T angle,Osborn wave,Lambda wave,heart rate turbulence,Twave alternans,etc.,are emerging promptly.Here,we will discuss them in detail.
