aThe negative chronotropic effect is most probably a result of an increased depolarization threshold of cardiac cells' membranes. The cumulative concentrations of calcium's antagonists cause negative chronotropic effect, which was achieved by direct effect of calcium on the sinus auricular knot. The anta...
It was demonstrated for the first time that transthoracic ultrasound has the potential to decrease the heart rate by ~20%. The negative chronotropic effect lasted for at least 15 min after ultrasound exposure and there was no apparent gross damage to the cardiac tissue. 展开 ...

1The chronotropic effects of a novel class III antiarrhythmic drug, UK-68,798, and the -adrenoceptor blocker, propranolol, for comparison, were studied on spontaneously beating right atria isolated from guinea-pigs in the absence and presence of increasing concentrations of isoprenaline (1010104m)....
Like propranolol, penbutolol exerts both a negative inotropic and a negative chronotropic effect on the heart, although there is some evidence that heart rate is reduced less with Penbutolol than with propranolol, and that Penbutolol may cause bradycardia less frequently. In healthy subjects mod...
Digitalis additionally possesses a negative chronotropic action that is partly a vagal effect and partly a direct effect on the sinoatrial node [41–43]. The therapeutic daily dose of digoxin ranges from 0.005 mg/kg in premature infants to as much as 0.75 mg in adults. Digoxin tablet ...
Among their diversified functions in the human body are mediation of rennin secretion and blood pressure, negative chronotropic effect on fetal and adult heart, serotonin release within gut enterochromaffin cells, inducing melanocyte pigmentation and differentiation, and sperm migration (Dalesio et al., ...
