心源性猝死(Sudden Cardiac Death,SCD)是临床上常见死因之一。据估计美国和欧州每年有近40万人发生SCD,如何识别和防止SCD的发生,成为医学界的重要课题。随着精密医疗仪器的发明与运用,如侵入性电生理学检查,Holter心电图监测等,使识别SCD高危病人有了可能;新型抗心律失常药物如胺碘酮等的出现,使高危病人的预后有所改观。然而,高危病人SCD发生率仍很高。这迫使临床医生积极寻找非药物治疗措施。如①手术切除可疑的致心律失常病灶。②经导管高能电消融病灶等。但前者
Sudden Cardiac Death (SCD) is one of the most common clinical causes of death. It is estimated that nearly 40 million SCDs occur each year in the United States and Europe. How to identify and prevent SCD has become an important topic in the medical community. With the invention and application of precision medical instruments, such as invasive electrophysiological examination, Holter ECG monitoring, so that the identification of high-risk patients with SCD possible; new anti-arrhythmic drugs such as amiodarone and so on, so that the prognosis of high-risk patients have Change. However, the incidence of SCD in high-risk patients is still high. This forces clinicians to actively seek out non-medical treatment. Such as ① surgical excision of suspected arrhythmia lesions. ② high-energy catheter ablation lesions. But the former
