Clinical Monitoring of Antiarrhythmics in Critical Care

Antiarrrhytmics are an important pharmacological class of drugs used in cardiology. The objective of this article is in particular to provide a greater understanding of the mechanisms of action of antiarrhythmics and, consequently, the clinical monitoring of expected outcomes. This article is divided into two parts. The first part, electrophysiology, illustrates the relationship between the action potential of the myocardial fiber and the point of impact of antiarrythmics. The second half, antiarrythmics, provides a classification of antiarrhythmics as well as the mechanisms of action of each class of antiarrythmics and their particularities, including clinical monitoring.
