概括
在持续性心房动 (AF) 时,单独进行异位触发性状 (ET-GP) 切除是可行的. 这种策略可以在一年内防止肌肉前列腺复发,提供新的治疗选择.
科学领域:
- 电生理学
- 心脏节律失常
- 最少侵入性心脏手术
背景情况:
- 之前的试验表明,对心房动 (AF) 进行状交 (GP) 切除是成功的.
- 作为治疗持久性肌前膜的独立策略,GP切除的有效性尚未得到研究.
研究的目的:
- 评估在持久性AF患者中绘制和切除左心房外皮触发性状 (ET- GP) 的可行性和有效性.
- 在没有肺静脉隔离 (PVI) 的ET-GP切除后评估1年的心房动 (AF) 或心房低心率 (AT).
主要方法:
- 持续性AF患者使用高频刺激 (HFS) 和切除进行ET-GP映射.
- 切除继续,直到确定的GP变得不功能;如果AF变得不间断,则会切除心房分离GP (AVD-GP).
- 没有进行肺静脉隔离 (PVI);患者被跟踪1年以评估AF/ AT复发.
主要成果:
- 49名患者完成了GP切除; 41%的患者持续了≥12个月的AF.
- 高频刺激 (HFS) 发现每名患者平均15±9名全科医生.
- 在该队列中,一年无任何AF/ AT的比例为33%,持续性AF的比例为51%. 与其他策略相比,只有ET-GP的消去率更高 (92%).
结论:
- 左心房ET-GP映射和切除是持续性AF的可行的独立策略.
- 这种方法可以有效地预防特定患者在一年后复发.

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias
160
Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Dysrhythmia management involves a multifaceted approach, incorporating pharmacological treatments, medical procedures, surgical interventions, lifestyle modifications, and patient education.Pharmacological ManagementAntiarrhythmic Drugs:Class I (Sodium Channel Blockers): This class includes quinidine and procainamide, which reduce the speed of impulse conduction in the heart, stabilize the cardiac membrane, and control arrhythmias. Quinidine and procainamide are Class IA agents that prolong the...
