Describing a medication or treatment that prevents or treats abnormal heart rhythms by helping the heart beat in a normal, steady pattern.
From 'anti-' (against) + 'arrhythmic' (irregular rhythm), from Greek 'a-' (without) + 'rhythmos' (rhythm). Medical terminology combined these Greek roots to name drugs that fight irregular heartbeats.
These drugs literally tell your heart to get back in the groove—when your heartbeat goes haywire, antiarrhythmic medications are like a metronome that puts it back in sync!
