Chronotropic and dromotropic
WebNov 18, 2024 · For me I remembered them with this little mnemonic: Inotrope - iron. Think iron is strong so strength of contraction. Chronotrope - chronos, clock. Think time, speed, rate of contraction. Dromotrope - drum. I think of people marching at the speed of the drum beat. This works like the AV nodal conduction speed, where the AV node is the drummer. WebMay 1, 1990 · The positive chronotropic response to SAS stimulation increased when the level of stimulation (i.e., stimulus pulse duration, pulse amplitude, and number of pulses …

WebWhat is chronotropic effect mean? A dromotropic agent is one which affects the conduction speed (in fact the magnitude of delay) in the AV node, and subsequently the rate of electrical impulses in the heart.Positive dromotropy increases conduction velocity (e.g. epinephrine stimulation), negative dromotropy decreases velocity (e.g. vagal stimulation). WebIn general, the CCBs exert negative inotropic, chronotropic, and dromotropic (conductive) effects. • Vascular smooth muscle is relaxed by CCBs, leading to peripheral vasodilation and coronary vasodilation. • In some cases, peripheral effects will activate a baroreceptor reflex in response to lowered blood pressure.
