Abstract

The authors show that the ventricular electrograms of recurrent monomorphic ventricular tachycardia (VT) having an identical 12-lead surface configuration can be matched to a template constructed from a previous episode of the same VT. This could allow assessment of the number of times a device has delivered therapy for a known VT, in addition to the total number of therapies for cardiac rhythms that may have exceeded a rate criterion and/or morphology criterion. Templates constructed during monomorphic VT in 12 patients were examined by means of correlation waveform analysis (CWA) and area of difference (AD). With CWA the VT templates correctly discriminated 902/936 (97%) ventricular depolarizations, and AD correctly discriminated 932/936 (99%) depolarizations when the same VT was reinduced. The study used acute leads positioned during electrophysiologic study and has not been tested or validated on chronic leads. The monomorphic VT was reinduced during a single electrophysiology study. Whether changes in heart substrate or structure may cause changes in the intracardiac VT morphology over time has not been determined.<>

使用心动过速模板识别复发性单形态室性心动过速

作者表明，复发性单型室性心动过速(VT)的心室电图具有相同的12导联表面结构，可以与以前的相同室性心动过速的模板相匹配。这可以评估设备为已知VT提供治疗的次数，以及可能超过速率标准和/或形态标准的心律治疗的总次数。采用相关波形分析(CWA)和差值面积(AD)对12例单形态VT时构建的模板进行检测。CWA的心室去极化模板正确识别902/936 (97%)，AD的去极化模板正确识别932/936(99%)。该研究使用电生理研究期间定位的急性导联，尚未对慢性导联进行测试或验证。单态室速在单次电生理研究中被重新诱导。心脏底物或结构的改变是否会随着时间的推移引起心内室速形态的改变尚未确定。
