Digoxin – ECG changes, arrhythmias, conduction defects & treatment
Digoxin ECG changes: arrhythmias, conduction defects and waveform changes Digoxin may be used in patients with heart failure , atrial fibrillation , atrial flutter , and in selected cases of paroxysmal supraventricular tachycardia. Due to its profound pro-arrhythmic effects and lack of compelling data regarding morbidity and mortality benefits , digoxin has been ousted repeatedly from the standard of care for these conditions . However, digoxin is still used in patients who do not achieve satisfactory effects using first-line therapies. Digoxin is also used frequently in the emergency setting to control ventricular rate during supraventricular tachycardias (e.g. atrial fibrillation ). Because digoxin may cause life-threatening arrhythmias, every healthcare provider must be able to recognize common digoxin ECG changes and arrhythmias. Digoxin effects on cardiac function and ECG Digoxin has a positive inotropic effect and a negative chronotropic effect, enhancing ventricular contractility while …
