概括
患有帕洛西斯马性心房动 (pAF) 病史的患者在持续性心房动 (psAF) 直接电流心脏转变 (DCCV) 后的复发率较高,相比之前没有pAF的患者. 早期节律控制可能对pAF患者有益.
科学领域:
- 心脏病学 心脏病学
- 电力生理学 电力生理学
背景情况:
- 偏心动脉动 (pAF) 可以通过心脏重塑发展为持续性心房动 (psAF).
- 一些患者在没有先前的pAF病史的情况下出现psAF.
- 患有pAF的病史可能会影响直流心脏转换 (DCCV) 后的复发率.
研究的目的:
- 为了调查pAF的病史是否会影响psAF的DCCV后复发率.
- 为了比较DCCV成功在患者和没有先前的pAF历史.
主要方法:
- 对565名患者进行前性研究,他们首次接受了psAF的DCCV.
- 根据先前的pAF病史 (原发性psAF与pAF病史) 分类的患者.
- 在DCCV后1个月和3个月进行标准化心电图随访.
主要成果:
- 81.6%的患者出现了原发性psAF.
- 以前患有pAF的患者左心房大小相似,但患有更多并发症 (心脏病,睡眠呼吸暂停,中风) 和使用抗心律失常药物.
- 在患有pAF (P=.0101) 的患者中,早期复发和更短的AF存活期 (1.6比5个月),即使在对药物使用进行控制后.
结论:
- 初级psAF患者对DCCV的反应更持久.
- 患有pAF病史的患者在DCCV后出现更高的复发率.
- 考虑对pAF患者进行积极的早期节律控制,因为DCCV复发的可能性更高.

01:28Disturbances in Heart Rhythm
930
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...

01:25Correlation between ECG and Cardiac Cycle
4.0K
The electrical signals recorded on an electrocardiogram (ECG) occur before the mechanical processes of contraction and relaxation during the cardiac cycle.
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...

01:28Mechanism of Cardiac Arrhythmias
909
Arrhythmias are irregular heart rhythms occurring when the heart's electrical impulses become abnormal. These disturbances can lead to various symptoms, depending on their severity and the underlying cause. Some common factors contributing to arrhythmias include hypoxia, ischemia, electrolyte imbalances, excessive catecholamine exposure, drug toxicity, and muscle overstretching. Arrhythmias can be classified into two main types based on the rate and site of origin of abnormal heart rhythms.

01:19Electrophysiology of Normal Cardiac Rhythm
2.9K
The normal cardiac rhythm is a synchronized electrical activity that facilitates the regular and coordinated contraction of the heart muscle. This process is essential for efficient blood circulation throughout the body. The fundamental elements involved in establishing and maintaining this rhythm include the unique electrical properties of cardiac muscle cells, the sinoatrial (SA) node's pacemaker function, the specialized conducting system, and the ionic mechanisms underlying each phase...

01:30Cardiac Action Potential
1.3K
Cardiac action potentials are essential for proper heart function, enabling the rhythmic contractions needed for adequate blood circulation. Nodal cells and Purkinje fibers, specialized for electrical conduction, generate these action potentials.
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.

01:16ECG Interpretation of Arrhythmias I: Sinus Arrhythmias
208
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,...
