CSF3 and ventricular tachycardia: To this extent, Baldo et al. have very recently suggested that GCSF might exert a direct stabilizing electrophysiological effect on infarcted myocardium independently of its genomic effects; in fact, its administration before coronary ligature in rats reduces the incidence of ventricular premature beats and ventricular tachycardia also in the following 30 min after MI occurrence [44].
