概括

传统的导管切除增加了皮肤交感神经活动 (SKNA),与高功率,短期设置不同. 这两种方法都显示出类似的心房的复发率,这表明HPSD可能会减少附带损害.

科学领域:

心脏病学心脏病学
自主神经系统研究自主神经系统研究
医疗器械技术医疗器械技术

背景情况:

对心房动 (AF) 的导管切除可以通过调节自主系统来改善.
皮肤交感神经活动 (SKNA) 提供了对交感活动的非侵入性评估.
关于不同能量设置在AF切除过程中如何影响SKNA的研究有限.

研究的目的:

为了研究AF剥离过程中SKNA在不同能量设置中的变化.
为了确定SKNA变化和AF切除结果之间的关系.

主要方法:

72名AF患者使用常规 (ConV) 或高功率短期 (HPSD) 能量设置进行了导管切除.
在射频除之前和之后,测量了右臂的SKNA.
分析比较了ConV和HPSD组之间的SKNA变化和1年AF复发率.

主要成果:

两组均具有类似的基线SKNA. 在消去后,SKNA在ConV组显著增加 (p=0.003),但在HPSD组没有.
在ConV组中,更高的消去后SKNA与没有AF复发相关.
一年AF复发率是可比的:ConV为35%,HPSD为28% (p=0.52).

结论:

经消去后的SKNA与传统设置相比增加,这表明与HPSD相比,神经调节效应不同.
尽管SKNA的反应不同,但两种能量设置的AF复发率在1年内都相似.
由于病变深度较小,HPSD策略可能会产生持久性病变,并减少附带损害.

关键词:

心房动是一种心房动.自主系统自主系统.高功率的短时间持续时间.肺静脉隔离肺静脉隔离肺静脉隔离皮肤的同情神经活动.

Dysrhythmias IV: Characteristics of Bradyarrhythmias

Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...

Local Anesthetics: Differential Sensitivity of Nerve Fibers

Local Anesthetics: Differential Sensitivity of Nerve Fibers

Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
