概括

右心房应变 (RASr) 是心转动后心房 (AF) 复发的更强的预测因素,而不是左心房应变 (LASr). 评估RA功能的改善AF复发风险预测在接受电心转换 (ECV) 的患者.

科学领域:

心脏病学心脏病学
心声回声扫描 (Echocardiography) 是一种心声回声扫描.
耳前的研究研究研究.

背景情况:

左心房 (LA) 机制有助于心房 (AF) 风险预测,但不能完全预测复发.
右心房 (RA) 功能在AF复发预测中的作用仍然不清楚.

研究的目的:

评估RA纵向储应变 (RASr) 的附加值,以预测AF复发后电心脏转变 (ECV).

主要方法:

对132名患有持续性AF的患者进行了回顾性研究,这些患者接受了选择性ECV.
在ECV之前,LA和RA的大小和功能的全面回声心脏图.
对AF复发终点进行12个月的随访.

主要成果:

在12个月内,在48%的患者中观察到AF复发.
与鼻腔节律相比,在AF复发的患者中降低了LASr和RASr.
RASr与AF复发 (AUC=0.77) 的相关性比LASr (AUC=0.69) 的相关性更强.
在多变量分析中,RASr与AF复发 (HR=3.26) 独立相关.

结论:

与LASr相比,RASr是AF复发后ECV的独立和更强的预测因素.
评估RA和LA的功能重塑对于管理持久性AF患者至关重要.

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

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...

Dysrhythmias V: Evaluating Dysrhythmias

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...
