Borderline left ventricles in prenatally diagnosed atrioventricular septal defect or double outlet right ventricle: echocardiographic predictors of biventricular repair.

abstract：:Potential antiarrhythmic effects of calcium (slow-channel)-blocking drugs ca be indirect or direct. The indirect effect would affect ischemia-induced arrhythmias by improving myocardial perfusion or decreasing myocardial oxygen consumption. The direct effect would affect the electrical activity of the sinoatrial (SA) ...
