Electrocardiogram findings of toxic adenoma are mainly due to thyrotoxicosis. Common ECG changes seen with toxic adenoma are sinus tachycardia and atrial fibrillation with rapid ventricular response.

Electrocardiogram findings of toxic adenoma are mainly due to thyrotoxicosis. Common ECG changes seen with toxic adenoma are:^[1]

• Sinus tachycardia
• Atrial fibrillation with rapid ventricular response
• Non-specific ST and T wave changes
• Ventricular extrasystoles
• Supraventricular arrhythmias (premature atrial beats, paroxysmal supraventricular tachycardia, multifocal atrial tachycardia, atrial flutter).
