Under normal conditions function of the right ventricle (RV) is determined by the heart rhythm, RV filling time, RV systolic synchrony and interdependence between both ventricles. Failure of the left ventricle (LV) can lead to RV failure. Impaired function of the RV significantly worsens the prognosis in patients after myocardial infarction and with LV failure. Permanent atrial fibrillation (AF) is one of the most common arrhythmia in patients with depressed RV function. Frequent coexistence of chronic heart failure (CHF) and AF causes overlapping of the arrhythmia and RV dysfunction in the setting of CHF. They may lead to hemodynamic compromise and worsen prognosis in patients with chronic RV failure of various etiologies. RV structure and function can be assessed in 2D, 3D echocardiography, cardiac magnetic resonance imagingand computed tomography.
在正常情况下，右心室（RV）的功能取决于心律、RV 充盈时间、RV 收缩同步性以及两个心室之间的相互依赖性。左心室（LV）衰竭可导致 RV 衰竭。RV 功能障碍显著恶化了心肌梗死后和 LV 衰竭患者的预后。永久性心房颤动（AF）是抑郁 RV 功能患者中最常见的心律失常之一。慢性心力衰竭（CHF）和 AF 经常同时存在，导致心律失常和 CHF 背景下的 RV 功能障碍重叠。它们可能导致血流动力学不稳定，并使各种病因的慢性 RV 衰竭患者的预后恶化。RV 的结构和功能可以通过 2D、3D 超声心动图、心脏磁共振成像和计算机断层扫描进行评估。
