概括

与常规方法相比,用于持续性心房动 (PsAF) 的射频剥离 (RFA) 期间的高密度映射显著降低了复发率,并改善了患者的健康结果.

科学领域:

心脏病学心脏病学
电力生理学电力生理学
医疗技术医疗技术医学技术

背景情况:

持续性心房动 (PsAF) 是一个重大的临床挑战.
射频除 (RFA) 是对PsAF的常见治疗方法.
通过先进的绘图技术优化RFA有效性至关重要.

研究的目的:

通过 PsAF 患者的高密度映射来指导 RFA 的临床有效性.
为了比较高密度映射和常规RFA组之间的复发率和患者报告的结果.

主要方法:

一项前性研究,涉及190名接受RFA的PsAF患者.
患者被分为两组:常规RFA (n=105) 和高密度映射RFA (n=85).
收集和比较了临床疗效指标,包括复发率和SF-36分数.

主要成果:

高密度映射组显示,与常规组 (23.81%) (p=0.025) 相比,术后复发率明显较低 (11.58%).
反映患者健康状况的SF-36分数在3,6和12个月后的高密度映射组显著更高 (p<0.05).
高密度基质映射被确定为防止复发的保护因素 (OR=0.453,p<0.001).

结论:

使用像PentaRay这样的电极进行高密度映射,可以在PsAF患者中更准确地表征心房基质.
由高密度映射指导的个性化废除策略提高了成功率并减少了不良事件.
这种方法显著提高了患者随后的健康状况.

Pulse rhythm

Pulse rhythm

Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac muscle...
