This text provides a review of drug therapy for cardiac arrhythmias, specifically focusing on the use and administration of quinidine, procaine amide, and potassium salts.
Historical review of quinidine, procainamide, and potassium leaves modern arrhythmia management open; prospective trials required before any clinical reconsideration.
Other aspects of the drug therapy of cardiac arrhythmias are as follows:Drugs That Decrease ExcitabilityThe most important of the drugs that decrease excitability are quinidine, procaine amide and potassium salts. These are indicated in the treatment of extrasystoles (atrial, ventricular or nodal) and paroxysmal tachycardia of atrial, nodal and ventricular origin.QuinidineQuinidine may be given orally, intramuscularly or intravenously. If parenteral administration is indicated, the intramuscular route is the method of choice. In the presence of a shocklike state, in which the intravenous route may be indicated, the drug should be dissolved in 50 to 100 ml. . . .
