Overview

An ECG in patients with diphtheria can be normal. However, in patients with diphtheria myocarditis, a wide range of abnormalities related to conduction and rhythm may be observed.

Electrocardiogram

An ECG in patients with diphtheria can be normal. However, in patients with diphtheria myocarditis, a wide range of abnormalities related to conduction and rhythm may be observed. Common ECG findings in cases of diphtheria myocarditis include:^[1]^[2]^[3]

Prolonged PR or QT intervals
Alterations in the ST segment, either elevation or depression
Alterations in the T wave
Atrioventricular block (AV block)
Bundle branch block (BBB)
Hemiblock
Sinus bradycardia
Arrythmias, such as supraventricular tachycardia (SVT) and ventricular tachycardia (VT)
