What is the Heliotropic Effect? posted by John Spacey, July 09, 2016 updated on January 19, 2017 The heliotropic effect is the hypothesis that societies, cultures, organizations, groups and individuals work towards the most positive images they hold of themselves.

Chronotropic effects (from chrono- , meaning time, and tropos, a turn) are those that change the heart rate. Chronotropic drugs may change the heart rate by affecting the nerves controlling the heart, or 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 node) conduction. A positive dromotrope increases AV nodal conduction, and a negative dromotrope decreases AV nodal conduction. A lusitrope is an agent that affects diastolic relaxation.
