Life-threatening consequences can be the result of inappropriate classification of ventricular fibrillation for patients with implantable cardioverter defibrillators. The objective of this study was to determine if analysis of the asynchronously paced evoked electrogram using the braided endocardial defibrillation lead could improve the detection of ventricular fibrillation. The depolarization portion of the evoked electrogram was integrated to obtain the paced depolarization integral. The results demonstrated that the mean of the paced depolarization integral, its SD, and the mean +/- SD were significantly different between sinus rhythm and ventricular fibrillation (p < 0.005, p < 0.05, p < 0.01, respectively). These results suggest that the paced depolarization integral obtained with the braided endocardial defibrillation lead could improve the specificity and sensitivity of ventricular fibrillation detection.
对于植入式心脏复律除颤器患者，心室颤动分类不当可能导致危及生命的后果。本研究的目的是确定使用编织心内膜除颤导线对异步起搏诱发的心电图进行分析是否能改善心室颤动的检测。对诱发心电图的去极化部分进行积分以获得起搏去极化积分。结果表明，窦性心律和心室颤动之间起搏去极化积分的平均值、其标准差以及平均值±标准差存在显著差异（分别为p < 0.005、p < 0.05、p < 0.01）。这些结果表明，使用编织心内膜除颤导线获得的起搏去极化积分可以提高心室颤动检测的特异性和敏感性。
