[Myocardial infarction in the course of digoxin and theophylline poisoning].

Abstract

The aim of this paper is to present a case of the patient who was hospitalized in the Toxicology and Cardiology Department because of suicidal digoxin and theophylline intoxication. Both drugs have complicated mechanism of action and affect cardiovascular system differently, but both predispose to ventricular and supraventricular arrhythmias. In the presented patient conduction disorders, cardiac muscle repolarization disorders and ventricular arrhythmias typical to digoxin poisoning were observed. During hospitalization the patient experienced the ECG and biochemical abnormalities resulting from myocardial infarction. In our paper we have analyzed digoxin and theophylline mechanisms of action and possible impact of each of these drugs on the clinical symptoms that our patient presented.
