epicardium

[ep′ikär′dē·əm]
Etymology: Gk, epi + kardia, heart
the outermost of the three layers of tissue that form the heart wall. It is composed of a single sheet of squamous epithelial cells overlying delicate connective tissue. The epicardium is the visceral portion of the serous pericardium and folds back on itself to form the parietal portion of the serous pericardium. Compare myocardium. See also pericardium. epicardial, adj.

epicardium

The inner layer of the bag surrounding the heart (the PERICARDIUM).

epicardium

the external covering of the HEART wall.

epicardium

On the other hand, in subepicardial ischemia there is a delay of cardiac subepicardial cells repolarization, as result, repolarization begins at the endocardium and moves into the opposite direction from the endocardium to the epicardium, decelerating upon reaching subepicardical ischemic area, this causes a prolonged QT interval and negative, symmetrical and deep T-wave (28-32).
Our proliferation data clearly confirm the role of the epithelium, esophagus, and epicardium as sources of cells during didemnid budding, as suggested earlier by histological examination lacking explicit proliferation analysis (Berrill, 1935; Brien and Van den Breede, 1948: Ki-tazawa, 1967; Groepler, 1992).
Paul Riley and colleagues have identified a rich source of dormant stem cells in the epicardium, the innermost layer of the sac, which surrounds the heart, reports New Scientist
The R' in Brugada syndrome is thought to be due to early repolarisation of the right ventricular epicardium rather than the right bundle branch block [79].
These mutations result in current transients from ventricular epicardium to endocardium which culminate in ventricular tachyarrhythmias.
Additional conduction delay from endocardium to epicardium then moves the J wave out of the QRS complex.
The heart is like a four-room house: The vinyl siding is epicardium, the walls are myocardium, and the glossy interior paint is endocardium.
Unlike other transcripts, Kcnd2 is expressed in a steep gradient from the epicardium to the papillary muscles (Dixon and McKinnon 1994).
During these stages, the epicardium begins to invest the outer surface of the heart.
The pericardial fat sign is a linear lucency more than 2 mm from the lower heart border, indicating separation of the parietal epicardial fat from the epicardium
