Chronotropic and dromotropic
WebFeb 2, 2024 · Atenolol has negative inotropic, chronotropic, and dromotropic effects. The negative inotropic effect weakens the contraction of the heart and lowers blood pressure. The negative chronotropic effect decreases the heart rate, and a negative dromotropic effect slows the conduction of the electrical charge in the heart.

WebCSNS activity is positively chronotropic (heart rate is increased), inotropic (the cardiac contraction is stronger), lusiotropic (relaxation is faster), and dromotropic (conduction of …
WebJan 5, 2024 · Dromotropic. The term dromotropic derives from the Greek word δρόμος drómos, meaning , a course, a race. 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. WebAug 14, 2024 · Whats up guys? Today I will talk about cardiac tropism and its different types. I will define - chronotropy, ionotrophy and dronotropy for you guys and at th...
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. WebA dromotropic agent is one which affects the conduction velocity of the AV node, and subsequently the rate of electrical impulses in the heart. [1] [2] Agents that are dromotropic are often (but not always) inotropic and chronotropic. For example, parasympathetic stimulation is usually negatively dromotropic, inotropic, and chronotropic.
