ECG changes caused by antiarrhythmic drugs, beta blockers & calcium channel blockers
The effect of antiarrhythmic drugs, beta-blockers and calcium channel blockers on rhythm, conduction and ECG waveforms Although the purpose of antiarrhythmic drugs is to control arrhythmias, these medications may also cause arrhythmias and confusing ECG changes. ECG changes and arrhythmias caused by digoxin were discussed previously. Below follows a rather detailed declaration of ECG changes, arrhythmias and conduction defects that occur due to antiarrhythmic drugs, beta blockers and calcium channel blockers (inhibitors). The reader will notice that most of these drugs are contraindicated in patients with structural heart disease, as well as patients with reduced left ventricular function. This is because these patients are at particularly high risk of developing life-threatening arrhythmias.
