Abstract
M-mode echography of the coronary sinus in the apical 2-chamber view enabled us to measure coronary sinus caliber at specific phases of the cardiac cycle. Coronary sinus narrowing occurs consistently during atrial contraction, but is always absent in atrial fibrillation; in patients with congestive heart failure and systemic venous congestion, this narrowing is significantly attenuated.
摘要
在心尖两腔视图下对冠状静脉窦进行M型超声心动图检查，使我们能够在心动周期的特定阶段测量冠状静脉窦口径。冠状静脉窦在心房收缩期始终会变窄，但在房颤时则始终不会变窄；在充血性心力衰竭和体静脉淤血患者中，这种变窄会明显减弱。
