Question?問題：

Inappropriate ICD shocks account for 30% of all ICD therapies and may be due to non-malignant supraventricular arrhythmias or over-sensing. What are causes of ICD over-sensing??

不適宜植入式轉(zhuǎn)復(fù)和除顫裝置（ICD）放電占所有ICD放電的30%，可能是由于非惡性室上性心律失常或過度感應(yīng)。什么會導(dǎo)致ICD過度感應(yīng)？

?Answer?答案：

True cardiac electrical signals (e.g. T-wave, double-sensing of very wide QRS complexes) and non-cardiac signals (eg. fractured lead, skeletal myopotentials, external electromagnetic interference) ()?

真正的心臟電信號（如T波，非常寬QRS雙感應(yīng)）和非心臟信號（如導(dǎo)聯(lián)斷裂，骨骼肌肌點位，外界磁場干擾）
