| An echocardiogram showed that the tip of the pacemaker catheter extended through the right ventricular apical wall of the epicardium. |
|
| It has been known that muscle fibers in a heart are arranged in such a way that their orientation changes continuously from endocardium to epicardium of the free wall. |
|
| Coronary vessels supplying arterial blood to the heart penetrate the epicardium before entering the myocardium. |
|
| Reference to the pericardium, epicardium, myocardium, endocardium and valves, chordae, ventricular thicknesses, and aorta and major vessels may be included. |
|
| The difference in the spacings in the top epicardium layer and the rest of the heart may indicate that sarcomere lengths in those regions are different. |
|
| Additional conduction delay from endocardium to epicardium then moves the J wave out of the QRS complex. |
|
| In the systolic and diastolic phases of heartbeat, two contour lines were drawn to delineate the endocardium and epicardium. |
|
| That work involved in effect turning the clock back in a layer of cells on the outside of the heart, called the epicardium, making adult cells think they were embryos again and thereby restarting their ability to repair. |
|
| We will study the role of macrophages and particularly analyse a subtype, which accumulates in the outer mesothelial layer of the heart, the epicardium. |
