概括
在高血压患者中,R波峰值时间 (RWPT) 可以检测心肌早期损伤. 这种简单的心电图测量是识别亚临床心肌功能障碍的实用工具.
科学领域:
- 心脏病学 心脏病学
- 医学诊断 医学诊断 医学诊断
- 生物医学工程 生物医学工程
背景情况:
- 高血压 (HT) 是心肌功能障碍的主要原因之一.
- 早期发现心肌功能障碍是具有挑战性的.
- 左心室全球纵向菌株 (LV-GLS) 检测到亚临床损伤,但仅限于常规使用.
- R波峰值时间 (RWPT) 可能表明导电延迟和结构改造.
研究的目的:
- 在HT患者中调查RWPT和LV-GLS之间的关联.
- 评估RWPT作为亚临床心肌功能障碍在高血压患者中的潜在标志物.
主要方法:
- 对403名高血压患者进行前性研究.
- 进行了跨胸腔心声学和12导电心电图.

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...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests
418
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
