Abstract The interaction of procainamide and diphenylhydantoin on atrioventricular conduction, intraventricular conduction and automaticity in both the nondigitalized and digitalisintoxicated dog heart was studied. Procainamide slowed both A-V conduction and intraventricular conduction in the nondigitalized and digitalis-intoxicated heart. Both of these effects were reversed by diphenylhydantoin, and in 50 per cent of cases, normal conduction was completely restored. In the complete heart block… Expand
The clinical use of diphenylhydantoin (dilantin) in the treatment and prevention of cardiac arrhythmias.
TLDR
It is concluded that with slow administration and careful electrocardiographic and blood pressure monitoring, diphenylhydantoin is a safe and valuable agent in both the treatment and prevention of cardiac arrhythmias. Expand

TLDR
DPH appears to have special utility in the treatment of ventricular arrhythmias, especially those which are digitalis-induced, and is effective when given prophylactically in clinical situations which predispose to the production of cardiac arrh rhythms. Expand
Electrophysiologic properties of procainamide in man.
TLDR
The electrophysiologic properties of procainamide were studied in 16 patients and correlated with plasma levels and the effective refractory period was prolonged in one patient, unchanged in a second and apparently shortened in a third; no toxicity was noted. Expand

DPH is highly effective against both atrial and ventricular arrhythmias resulting from digitalis toxicity and should be considered one of the primary antiarrhythmic drugs in this clinical situation.Expand
The effect of diphenylhydantoin sodium (Dilantin) on myocardial contractility and hemodynamics.
TLDR
Dilantin, when administered intravenously, diluted in saline, resulted in a downward and leftward shift of the myocardial force-velocity relation, indicating depression of theMyocardial contractile state, and there was a precipitate fall in LV systolic pressure, and a marked rise of LVEDP, indicating hypodynamic myocardIAL failure.

Suppression of ventricular automaticity by antidysrhythmic agents.
TLDR
All four substances depressed automaticity, however, propranolol was effective at doses substantially lower than those required to antagonize several experimental dysrhythmias. Expand
Electrophysiologic Effects of Nitroglycerin during Experimental Coronary Occlusion
TLDR
TNG enhances the electrical stability of the acutely isChemic myocardium by decreasing the difference of refractory periods between nonischemic and ischemic areas in the immediate period following occlusion, and since TNG has no significant effects on ventricular automaticity, its beneficial effects might be limited in suppression of arrhythmias of re-entrant origin.

ELECTROPHYSIOLOGIC EFFECTS OF TNG Refractory periods of ventricular myocardium
Previous studies have shown that nitroglycerin (TNG) exerts beneficial electrophysiological effects in the setting of acute myocardial ischemia. To investigate the basis for these actions, theExpand
Procainamide-induced sinus node dysfunction in patients with chronic renal failure.
TLDR
Procainamide may produce electrophysiologic features of "sick sinus syndrome" in patients with chronic renal failure even when blood levels of this substance are being monitored, including elevated levels of N-acetyl procainamide. Expand
Electrophysiologic effects of partial coronary occlusion and reperfusion.
TLDR
The decrease in local refractory period and prolongation of conduction time result in underlying electrical instability predisposing to reentrant arrhythmias whereas automaticity is unchanged, and these abnormalities are fully abolished when reperfusion is instituted after 60 minutes of partial coronary occlusion.

The Electrophysiological Properties of Diphenylhydantoin Sodium as Compared to Procaine Amide in the Normal and Digitalis‐Intoxicated Heart
TLDR
It is concluded that the electrophysiological properties of diphenylhydantoin sodium make it an excellent agent in treating digitalis-induced arrhythmias. Expand
The contrasting effects of diphenylhydantoin and procaine amide on A-V conduction in the digitalis-intoxicated and the normal heart.
TLDR
The selective effects of DPH are in contrast with agents such as procaine amide which depress both ventricular ectopia as well as A-V transmission in the digitoxic heart, however, DPH is contra-indicated in complete heart block. Expand

TLDR
Ventricular tachycardia, which appears in about 2% of the cases, is admitted to be a serious complication of acute myocardial infarction and is therefore a situation which calls for prompt, exact diagnosis and therapy. Expand

TLDR
In 55 patients with various auricular and ventricular arrhythmias, continuous electrocardiograms were made during and after the intravenous administration of procaine amide hydrochloride, and no indication of drug-induced ectopic ventricular activity was found. Expand

TLDR
The search for effective but less toxic antiarrhythmic drugs has involved a number of different compounds, including the antimalarials, antihistaminics, antispasmodics and various agents that alter the responses of the autonomic nervous system. Expand

TLDR
At present, a common precipitating cause of digitalis toxicity is hypokalemia resulting from the use of saluretic drugs in conjunction with digitalis. Expand
