在心脏粉症 (CA) 中,右心室电解剖学电压映射 (EVM) 显示了与粉体负荷相关的电图幅度减少. 在CA患者中,RV EVM对心脏不良事件具有预后价值.
科学领域:
- 心脏病学 心脏病学
- 电力生理学 电力生理学
- 心脏成像 - - 心脏成像
背景情况:
- 心脏粉症 (CA) 是一种具有高心脏事件风险的透性心肌病.
- 右心室 (RV) 电解剖学电压映射 (EVM) 被探索其在CA中的作用.
研究的目的:
- 在CA患者中描述RV EVM.
- 评估RV EVM在CA中的临床价值.
主要方法:
- 15名疑似CA患者接受了RV高密度EVM和内心肌活检 (EMB).
- 电图特征和电解剖学数据与组织病理学和1年结果 (死亡或心力衰竭住院治疗) 相对相关.
主要成果:
- RV电图幅度与粉样蛋白负载 (P < 0.025) 相反相关.
- 在AL CA.中观察到较低的幅度.
- 在EVM上RV痕的范围预测了不良结果 (OR2.40,P=0.037).
结论:
- RV电图的振幅可以量化CA中的粉样蛋白负担.
- RV EVM在CA中显示了对心脏不良事件的预后价值.

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.
