Heart rhythm
Your heart rhythm is the pattern and regularity of your heartbeats, meaning how evenly spaced they are over time. An ECG shows this rhythm as the spacing and consistency of the waves across the tracing.
A steady, regular rhythm reflects a heart whose electrical signals are firing in a coordinated way. When the rhythm becomes irregular, too fast, or too slow, it's called an arrhythmia, and understanding it helps clinicians gauge how well the heart is coordinating each beat.
An irregular or abnormal rhythm can range from harmless extra beats that many people feel as a flutter to more significant arrhythmias like atrial fibrillation that may raise other health considerations. Because the meaning varies so widely, an irregular rhythm on a tracing should always be reviewed by a clinician who can weigh it against your symptoms.
A rhythm described as regular generally suggests evenly spaced, coordinated beats, though a single reading is a snapshot and doesn't capture rhythms that come and go.
A regular heart rhythm is the usual healthy pattern, but any concern about skipped, racing, or uneven beats is best evaluated by a clinician, ideally with an ECG. Rhythm is a clinician's read, not something to self-diagnose from an automated label.
