ABSTRACT: Rapid-scanning cofocal microscopy has been applied to the analysis of early phase Ca2+ transients in ventricular and atrial cardiomyocytes. On electrical stimulation of ventricular myocytes, Ca2+ concentration begins to rise earliest at the Z-line level and becames uniform throughout the c...
