Inotropic, Chronotropic and Dromotropic are different types of cardiac drugs. This classification is based on the way these drugs are used for the treatment of a particular condition. Inotropic drugs affect the force of cardiac contraction. Chronotropic drugs affect the heart rate. Dromotropic drugs affect conduction velocity through the conducting tissues of the heart.
Chronotropic effects (from chrono-, meaning time, and tropos, "a turn") are those that change the heart rate.. Chronotropic drugs may change the heart rate and rhythm by affecting the electrical conduction system of the heart and the nerves that influence it, such as by changing the rhythm produced by the sinoatrial node.Positive chronotropes increase heart rate; negative chronotropes decrease ...
Mar 3, 2011 · Introduction. Chronotropic incompetence (CI), broadly defined as the inability of the heart to increase its rate commensurate with increased activity or demand, is common in patients with cardiovascular disease, produces exercise intolerance which impairs quality-of-life, and is an independent predictor of major adverse cardiovascular events and overall mortality.

Find out exactly how your autonomic nervous system has a chronotropic effect (i.e. timing) that changes speed of your heartbeat! Rishi is a pediatric infectious disease physician and works at Khan Academy.
May 11, 2019 · Introduction. Cardiovascular diseases (CVDs), by claiming 17.1 million lives a year, bring about a third of universal deaths [].One example of these diseases are arrhythmias which are derangement in the normal rhythm of the heartbeat that results from irregularity at transmission or production of impulses in heart or mixture of both [].Diabetes, obesity, hypertension, dyslipidemias, cigarette ...
chronotropic: ( kron'ō-trop'ik ), Affecting the rate of rhythmic movements (for example, heartbeat).
Sinus Rhythms. In Chou's Electrocardiography in Clinical Practice (Sixth Edition), 2008. CHRONOTROPIC INCOMPETENCE. Chronotropic incompetence is an attenuated heart rate response to exercise that has been shown to be independently predictive of mortality and coronary heart disease risk in healthy populations even after adjusting for age, physical fitness, standard cardiovascular risk factors ...
