Bathmotropy

As bathmotropic (from ancient Greek βαθμός bathmos "threshold" and τρόπος tropos is known to influence the "twist direction") threshold or the excitability of the heart . In physiology, the stimulus or excitation threshold is understood to mean the smallest current strength or voltage that leads to the triggering of an action potential and thus to the contraction of the heart muscle cells . The arousal threshold is regulated endogenously primarily by the autonomic nervous system and can be influenced by medicinal substances. Positive bathmotropic substances such as adrenaline , noradrenaline and cardiac glycosides lower the arousal threshold, while negative bathmotropic substances such as acetylcholine and lidocaine increase the arousal threshold.
