Uncomplicated fever produces benign ECG changes in young men; supports physiological interpretation but leaves open generalizability beyond this cohort.
Does acute febrile infection alter cardiac rhythm and conduction in young men?
Uncomplicated fever physiologically increases heart rate and shortens PR and QT intervals; deviations such as interval prolongation or ventricular ectopy should raise suspicion for cardiac complications.
