Cardioactive alkaloids

Pharmacologic testing procedures for the cardioactive alkaloids pro- dde three types of information (1) alterations in the normal physiologic activities of the heart (2) conversion of artificial cardiac arrhythmias to normal sinus rhythm (3) compensation for the experimentally induced congestive heart failure. [Pg.81]

The answer is 3 [IIC Tible 15-1]. The halocarbon compounds (e.g., chloroform, halothane, freon) and the fumes from overheated synthetic fluorine-containing resin-coated (Teflon) cookware are indirectly car-diotoxic because they sensitize the heart to sympathomimetic amines such as epinephrine. Following exposure to these substances, even the release of endogenous epinephrine associated with stress can pose a hazard. Yew plants contain a cardioactive alkaloid that inhibits depolarization and produces bradycardia and diastolic heart block. Furazolidone interferes with intermediary metabolism, resulting in a lack of energy arid a dilated, weak heart "round heart." Digitalis aflecTs potassium content in the cell. Monensin is an ionophore that alters the sodium-to-calcium ratio arid leads Id cardiac necrosis. [Pg.169]
