An alternative spelling of allorhythmia; an abnormal or changed heart rhythm.
From Greek 'allo-' (other) + 'rhythmia' (rhythm). This variant spelling appears in some medical literature as a synonym for allorhythmia, though the 'allo-' form is more standard.
This double-r spelling variant shows how medical terminology can have pronunciation-driven spelling variations—'allorrhythmia' emphasizes the 'rh' digraph, making it sound more like ancient Greek medical words that physicians learned.
