概括
诊断时的持续性心房动 (PsAF) 并没有影响废除结果. 这项研究没有发现心房的复发或 PsAF 与心房 (PAF) 的患者的负担减去后的心脏动的差异.
科学领域:
- 心脏病学 心脏病学
- 电子生理学 电子生理学
- 医学研究 医学研究
背景情况:
- 持续性心房动 (PsAF) 在一些没有先前心房动 (PAF) 病史的患者中被诊断为心房动.
- 之前的研究表明,经过切除的PsAF患者的结果更差.
- 这一PsAF亚组的特征和废除结果需要进一步调查.
研究的目的:
- 将PsAF在诊断时的人口和电生理学特征与PAF进展的特征进行比较.
- 评估初始AF模式对剥离后复发率的影响.
主要方法:
- 持续性心房动 (CAPLA) 试验的导管切除将PsAF患者随机分为肺静脉隔离 (PVI) 加上后左心房壁隔离 (PWI) 或单独PVI.
- 随访时间为12个月,结果在3个月的空白期后进行评估.
- 数据包括334名患者,其中194人被诊断为PsAF,140人患有PAF.
主要成果:
- 与PAF患者相比,在诊断时患有PsAF的患者更年轻,心力衰竭率更高,射出分数更低.
- 在诊断时的PsAF中,AF复发率为43.8%,在PAF中为50%.
- 诊断时的PsAF在单变量或多变量分析中没有显著影响复发风险;AF负担,左心房大小和双极电压在组之间是相似的.
结论:
- 最初诊断时心房的模式不会影响CAPLA队列中导管切除后的AF复发率或AF负担.
- 这些发现表明,最初的AF呈现可能不是预测PsAF患者的切除成功的关键因素.

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...

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...

01:28Disturbances in Heart Rhythm

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.

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...

Dysrhythmias, also known as arrhythmias, are disturbances in the heart's rhythm that range from benign to life-threatening. A thorough evaluation is crucial for appropriate management and involves a comprehensive medical history, physical examination, and various diagnostic tests.Medical HistorySymptoms: Collect detailed information on palpitations, dizziness, syncope, chest pain, and fatigue. Note their onset, frequency, and triggers.Previous Cardiac Issues: Document any history of heart...

Tachyarrhythmias are a type of dysrhythmia where the heart rate exceeds 100 beats per minute. Here are some common types of tachyarrhythmias:Sinus TachycardiaSinus tachycardia originates from increased impulses from the sinus node, leading to an elevated heart rate. It is often triggered by stress, fever, or exercise.Patients may experience palpitations, a sensation of a racing heart, dizziness, and chest discomfort.Causes and Risk Factors: Common causes include physical exertion, emotional...
