1. Understand the Structure: The coronary sinus is a large vein that collects deoxygenated blood from the heart muscle (myocardium). 2. Identify the Location: The coronary sinus is located on the posterior surface of the heart. It is situated between the left atrium and the left ventricle. ...
An implantable lead is provided for delivering electrical therapy. The lead, suitable for placement and passive anchoring in a vessel within the coronary sinus region of a patient's heart, comprises a lead body having a distal end carrying at least one electrode electrically connected to a ...

The coronary sinus opens into A right atrium B superior vena cava C inferior vena cava D right ventricle E left atrium [正确答案]:A [本题分数]:1.0分 第20题 Which one is WRONG about the pericardium A It is located in the middle mediastinum B It can be divided into fibrous and serous ...
The right and left coronary arteries, branches of the ascending aorta, supply blood to the walls of the myocardium. After blood passes through the capillaries in the myocardium, it enters a system of cardiac (coronary) veins. Most of the cardiac veins drain into the coronary sinus, which open...

The heart is made up of muscle tissue; as such, it requires oxygen for metabolism to occur. Blood vessels provide the heart with oxygen-rich blood, as well as carry away carbon dioxide. The coronary arteries and sinus are responsible for this function....
Unroofed coronary sinus and coronary sinus orifice atresia: Implications for management of complex congenital heart disease Objectives. The aim of this study was to assess the morphology of the coronary sinus, its drainage and associated cardiac malformations when there is eithe... GD Groot - 《Jour...
Further, with respect to the right atrial sensing and pacing electrode 442, it is located on the lead 432 so that the electrode 442 is adjacent the ostium 19 of the coronary sinus within the coronary sinus. This has been found to provide effective right atrial pacing and sensing ...
