Aim: To study the anatomy of the coronary venous system in cadaveric hearts, to ascertain various morphological features of the coronary sinus in order to compare male and female coronary sinus.In addition to provide anatomical basis for the cannulation of coronary sinus and its tributaries. Methods; The study was performed on 40 hearts from embalmed cadavers in different age group varies from ...

The electromotive force of the ventricular tissues with different anatomy and activation patterns was studied. The left ventricular wall was perfused with Tyrode's solution from the circumflex branch of the left coronary artery and was stimulated first at an epicardial and then endocardial site to induce ectopic beats. The early QRS voltage was compared with the activated area at the same insta...

background: the right ventricular (rv) dyssynchrony has not been studied extensively and the existing literature has established the effect of cardiac resynchronization therapy (crt) on the left ventricular (lv) dyssynchrony, but there is a dearth of data on the effect of crt on the forgotten ventricle . we sought to evaluate the presence of mechanical right ventricular dyssynchrony in patients...
