Introduction
Overview
Overview
There are no specific ECG changes due to adrenal atrophy. However it consequences such as hyperkalemia may change ECG.
Electrocardiogram
Electrocardiogram
The adrenal atrophy does not alter the ECG patterns, itself. However, its consequent metabolite abnormalities, mainly hyperkalemia, can cause significant ECG patterns including peaked T waves, P wave widening/flattening, PR prolongation, bradyarrhythmia including sinus bradycardia, high-grade AV block with slow junctional and ventricular escape rhythms, slow AF, conduction blocks including bundle branch block, and fascicular blocks, and QRS widening with bizarre QRS morphology.[1]
A classic ECG in a hyperkalemic patient is shown:
