科学领域:
- 心脏病学 心脏病学
- 电子生理学 电子生理学
- 临床风险预测预测
背景情况:
- 在直流心脏转变 (DCCV) 后心房失常的复发是常见的,但风险因素尚未得到充分了解.
- 预测复发对于管理患者和优化治疗策略至关重要.
研究的目的:
- 开发和验证一项临床预测风险评分,用于第一个DCCV后心房 (AFL) 复发.
- 确定与AFL复发风险增加相关的关键因素.
主要方法:
- 在退伍军人事务EP数据库 (2002-2016) 中,预期将接受DCCV的心房失常患者纳入退伍军人事务EP数据库 (2002-2016).
- 使用Kaplan-Meier分析,比较心房动 (AF) 和AFL之间的复发时间.
- 开发REAL-PDX风险评分使用Cox比例危险建模在衍生队列和验证在一个单独的队列.
主要成果:
- 复发的中位时间在AFL (1.7年) 比AF (3.4个月) 显著长.
- AFL复发的独立预测因素包括慢性病 (CKD),老年,左心房 (LA) 扩张和诊断后的更长时间.
- REAL-PDX评分 (病,年龄≥65,LA扩张,先前诊断) 在验证队列中有效地将患者分为高风险和低风险组,显示复发时间显著缩短,高风险组的风险更高.
结论:
- REAL-PDX风险评分是一个简单而有效的工具,用于预测DCCV后AFL复发.
- 这一分数可以帮助临床医生在指导有关抗凝血药,洞穴皮峡移除或肺静脉隔离的决策.

164
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...

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 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...

136
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...

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...
