A method of treating irregular electromechanical waves in the myocardium of a subject with a cardiovascular disease, the method comprising injection of a conductive suspension into the myocardium on one or more lines, wherein the one or more lines are circular lines perpendicular to the electrical axis of the heart or open lines;
- wherein the open lines are selected from a group consisting of lines along the left bundle of His, lines along the atrioventricular node, and lines located along affected parts of the electrical conduction system,
- wherein the conductive suspension comprises carbon micro particles or noble metal micro particles, and
- wherein the injection along circular or open lines supports synchronized depolarizations of cardiomyocytes.
