在预测病人心律失常性猝死方面 ,像QRS波群时限等一些简单的临床指标比以往更加受到重视 ,尤其在确定哪些病人可能从植入除颤器 (ICD)及再同步化治疗中获益最大时利用这些指标可降低效益费用比。目前尚无大规模随机试验证实QRS波群时限可作为心律失常性猝死的预测因子并据此安?
In terms of predicting sudden cardiac arrhythmia in patients, simpler clinical indicators such as the QRS complex time limit have received more attention than ever before, especially in determining which patients may benefit most from implantable defibrillator (ICD) and resynchronization therapy When using these indicators can reduce the cost-benefit ratio. No large-scale randomized trials have confirmed that the QRS complex time limit can be used as a predictor of sudden cardiac arrhythmia.
