使用脉冲场切除的肺静脉隔离的学习曲线约为20个程序. 在60个病例后,PVI的长期耐用性得到改善,在学习曲线或使用3D- EAM期间,心律失常复发率没有显著差异.
科学领域:
- 电生理学
- 心血管切除技术
- 医疗设备的学习曲线
背景情况:
- 肺静脉隔离 (PVI) 使用单次脉冲场切除 (PFA) 是一种新的技术.
- 预计PFA的学习曲线很短.
- 三维电解剖绘制 (3D-EAM) 可能有助于缩短学习曲线并提高病变的耐用性.
研究的目的:
- 通过使用PFA对PVI的过程性性能标记进行评估.
- 评估3D-EAM对PVI结果的影响.
- 分析与PFA相关的PVI学习曲线.
主要方法:
- 分析了1008名使用PFA进行PVI的患者.
- 根据操作人员的经验和计划的病变组,选择性地使用3D-EAM.
- 在手术后3,6个月和12个月,对患者进行了心律失常复发的跟踪.
主要成果:
- 对手术和光学时间的学习曲线分别为18个和8个手术.
- 在学习过程中 (65%) 和学习过程结束后 (68%) 没有心律失常的12个月是相似的 (20例).
- 经过每名操作人员60次手术后,PVI的耐用性显著提高 (61%对比73%).
结论:
- 基于程序效率,单射PFA的学习曲线大约为每个操作员的20个案例.
- 在60例以上的病例中,PVI的长期耐用性得到显著改善.
- 无论是学习曲线阶段还是3D- EAM的使用都没有影响心律失常的复发率.

When a drug is administered through a constant intravenous infusion and eliminated via nonlinear pharmacokinetics, it follows zero-order input. For example, oral drugs undergo first-order absorption upon administration and are eliminated through nonlinear pharmacokinetics.
In the case of subcutaneously administered drugs,...
