WebCardiac chronotropic analysis has only begun to develop into a clinically relevant science. In the past, formal exercise testing was usually relegated to the assessment of ischemia or cardiac rehabilitation. The establishment of rate-responsive pacemakers as a potentially effective treatment for chr … 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 …
