Phenytoin-Induced Cardiac Conduction Abnormalities

Abnormalities of cardiac conduction in diabetics.

Crack Cocaine-Induced Cardiac Conduction Abnormalities Are Reversed by Sodium Bicarbonate Infusion

We report a dramatic case of a 19-year-old man with crack cocaine overdose with important clinical complications as cardiac arrest due to ventricular fibrillation and epileptics status. During this intoxication, electrocardiographic abnormalities similar to those found in tricyclic antidepressant poisoning were observed, and they were reversed by intravenous sodium bicarbonate infusion.

Cardiac conduction abnormalities during percutaneous balloon mitral or aortic valvotomy.

To evaluate the electrophysiologic changes in the cardiac conduction system that occur during percutaneous mitral or aortic balloon valvotomy, we prospectively studied the conduction system in 19 patients (10 mitral, 8 aortic, and 1 both) undergoing this procedure. A His bundle electrogram was recorded in all patients, and when sinus rhythm was present, the atrioventricular (AV) node effective ...

Phenytoin-induced gingival overgrowth.

Gingival overgrowth is a common adverse effect of therapy with Phenytoin, having important medical and cosmetic implications. Poor periodontal hygiene is an important risk factor for severity of Phenytoin-induced gingival overgrowth (PIGO), which is a time-dependent process. There is complex interplay of altered fibroblast biology, connective tissue turnover, inflammatory processes, and growth ...

Phenytoin induced status epilepticus.

T here is a growing body of literature that patients on antiepileptic drugs may experience worsening of seizure control such as increasing frequency, inducing new seizures, refractory seizures, and so forth. 1 Phenytoin is used in all types of seizure except absence seizure and is the most commonly prescribed antiepileptic drug due to its cost and availability. 2 Phenytoin is known for its side...
