概括
左心房 (LA) 应变参数和LA刚度指数 (LASI) 有效预测心转动 (CV) 后心房 (AF) 复发. 收缩性菌株显示为AF复发的长期预测因素具有前途.
科学领域:
- 心脏病学 心脏病学
- 医疗成像医学成像
- 电力生理学 电力生理学
背景情况:
- 心脏转移 (CV) 后心房动 (AF) 的复发仍然是一个临床挑战.
- 预测AF复发后CV的预测标记对于患者管理至关重要.
- 传统标记在预测长期结果方面存在局限性.
研究的目的:
- 评估LA应变参数和LASI对AF复发电后CV的预测值.
- 将这些新型标记与传统的心声回声学,生化学和临床因素进行比较.
- 为了确定早期和晚期AF复发的可靠预测因素.
主要方法:
- 一项前性观察试点研究,涉及31名患有持续性AF的患者,接受电动CV.
- 心声学评估包括LA菌株 (水库,管道,收缩),LASI,LAVI,LAA形态,LVEF,RA区域和RVSP.
- 在CV后3个月和6个月监测AF复发.
主要成果:
- 在3个月后,LA储,管道和收缩菌株与AF复发有负相关性 (p<0.001).
- LASI和E/E'比率与3个月后的复发有积极联系 (p<0.001).
- 在6个月后,只有收缩性应变 (p=0.008) 和LVEF (p=0.003) 仍然是显著的预测因素.
结论:
- 在预测早期的AF复发后,LA菌株参数和LASI是有价值的.
- LA收缩性菌株成为更强大的节律结果的长期预测器.
- 由于试点性质和样本规模较小,需要在更大的研究中进一步验证.

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias
464
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...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
