Electrocardiographic Changes Caused by Drugs and Electrolyte Abnormalities
A number of cardioactive drugs can cause changes in the electrocardiogram (ECG), the antiarrhythmic agents in particular. The most important effects produced by these drugs are bradyarrhythmias, which have been discussed in detail in Chap. 5. In this chapter, we will examine some of the specific effects of individual drugs, with special emphasis on their proarrhythmic effects.
