Chronotropy and dromotropy

WebChronotropic 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 heart rate. A dromotrope affects atrioventricular node (AV ...

WebMar 15, 2024 · The first four –tropies were first described in 1897 by TW Engelman. TW Engelman was a physicist, botanist, and microbiologist. He taught physiology in Germany in the late 1800s and early 1900s. These first four –tropies were inotropy, chronotropy, dromotropy and bathmotropy. It was not until 1982 that the 5th –tropy was described. … WebHeart lacks force to pump all the blood needed: Systolic or Contracting Dysfunction.
