概括
与右心房附属体 (RAA) 相比,低心房隔膜 (LAS) 节奏显著降低了鼻功能障碍 (SND) 患者的新发性心房动 (AF). 拉斯维加斯节奏提供了一个更安全的替代品来植入心脏起器,
科学领域:
- 心脏病学
- 电生理学
- 医疗器械
背景情况:
- 在双室心脏起器植入后,阴道节功能障碍 (SND) 患者面临心房动 (AF) 的风险增加.
- 耳前电极的位置会影响AF发生,这是心血管事件的危险因素.
研究的目的:
- 在SND患者中研究低心房隔膜 (LAS) 和右心房附带 (RAA) 节奏之间的新发性AF发病率差异.
- 探索基于节奏位置的AF发生变化的潜在机制.
主要方法:
- 包括155名SND患者:83名 (LAS调节) 和72名 (RAA调节).
- 收集了基线,心电图和心声图数据,以及手术后的结果和1年AF发生率.
- 分析了手术持续时间,P波参数和累积的心室节奏 (Cum % VP).
主要成果:
- 激发LAS的手术时间较长,但手术内P波幅较低.
- 在LAS节奏测试中,P波持续时间和Cum%VP显著降低.
- 一年内新发性肌动脉发生率为16. 9% (LAS) 和36. 1% (RAA) (HR: 0. 363,P=0. 019).
- 独立的AF风险因素包括捆绑分支,大左心室和P波持续时间.
- 激发LAS与降低AF风险相关 (OR为0.072,P=0.011).
结论:
- 在SND患者中,相比RAA,LAS刺激显著降低了1年的AF发生率.
- 激活LAS可以缩短术后P波的持续时间,并减少Cum% VP,从而可能预防AF.
- 在SND患者中,LAS步调是一种更安全的双腔心脏起器植入策略.

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...

114
Dysrhythmias, also known as arrhythmias, are irregular heart rhythms that result from abnormal electrical activity in the heart, affecting its ability to circulate blood efficiently. Tachyarrhythmias, a subset of dysrhythmias, are characterized by abnormally fast heart rates exceeding 100 beats per minute. Here are some types of tachyarrhythmias with their distinct ECG features:Sinus Tachycardia:Sinus tachycardia presents a regular heart rhythm with an increased rate of 101-180 beats per...

409
Arrhythmias are disturbances in the heart's rhythm that lead to abnormal heartbeats. These irregularities can originate from different parts of the heart and are classified based on their origin and nature.
Types of Arrhythmias
Sinus Node Arrhythmias
Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism,...

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...

01:29Disturbances in Heart Rhythm
1.2K
Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

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...
