在基质映射中识别旋转激活模式 (RAP) 的最佳心律取决于痕位置. 在痕附近步行可以帮助确定关键心室动脉冲动 (VT) 区域.
科学领域:
- 电力生理学 电力生理学
- 绘制心脏地图是指绘制心脏地图.
- 腹腔动脉高心率 (Ventricular Tachycardia) 是一个常见的情况.
背景情况:
- 导电块附近的旋转激活模式 (RAP) 与临界心室动脉障 (VT) 区域相关.
- 在基质映射期间的波面方向影响RAP和块线表现.
研究的目的:
- 为了确定最佳的心律,用于识别RAP和块线在基质映射.
主要方法:
- 追溯分析71个高密度基质图,来自46名接受静脉管切除的患者.
- 在鼻腔,RV节奏,LV节奏和双心室节奏节奏期间评估RAP外观.
主要成果:
- 在34%的地图中发现了RAP,有利于带有单向波浪的区域.
- 根据痕位置和节奏节奏 (阴道/心房,RV节奏,LV节奏) 的不同,RAP识别概率有所不同.
- 在不同节奏的重绘过程中,RAP在13名患者中变得明显.
结论:
- 最佳的基质映射节奏是由目标区域的空间分布决定的.
- 从痕附近的部位开始步行可以提高关键VT区域的识别.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
