Magnesium's Mechanism of Action in Digitalis-induced Arrhythmias
The mechanism by which magnesium affects digitalis-induced arrhythmias was studied in dogs with and without beta-receptor blockade. Digoxin was infused at a rate of 2.5,ug/kg/min until ventricular tachycardia developed, then half the animals were given MgSO4, the other half saline. In animals given MgSO4, sinus rhythm was immediately re-established; in animals given saline, ventricular tachycar...

متن کاملThe Action of Digitalis in Pneumonia
We have shown in a series of 105 cases of pneumonia, 95 of which we have selected as available for statistical study, that digitalis given by mouth has an action on the heart. We have judged this action to be present because changes occurred in the auriculoventricular conduction time and in the form of the T wave of the electrocardiogram, just as they do in the non-febrile heart. This conclusio...
متن کاملIons and the action of digitalis.
Digitalis acts mainly on the heart. It affects excitability, conduction of impulses, and force of contraction. The physiology of all these processes has been elucidated greatly in the past 20 years, particularly by Hodgkin and Huxley and their collaborators. Techniques of inserting micro-electrodes into nerve and muscle cells have made possible both the recording of transmembrane potentials in ...
متن کاملMechanism of Action of the Thyroid Hormone on the Heart
SUMMARY The foliowing cardiac effects may be attributed to thyroxin: 1-Thyroxin augments all anaerobic processes in the body includ::ng the heart, and decreases the glycogen content of the heart ( 1, 2, 5, 27). The resistance of the heart to anoxia is increased in hyperthyroidism ( 25). 2- Thyroxin influences the cardiac weight and prevents cardiac atrophy (3, 8, 10, 11, 19, 20, 21, 30...
