An ANOMALY is a deviation from what is regarded as normal.
Arrhythmia or dysrhythmia are both used to mean abnormal heart rhythm. Examples are atrial fibrillation and 2nd degree heart block.
It's common to see a normal examination of the heart notated with the abbreviation S1 S2 NSR, meaning there was a normal "lub," a normal "dub," and a normal sinus rhythm ("NSR"). Some argue that you can't "hear" a normal sinus rhythm, but can only advise the rhythm is regular.

Palpitation is the medical term meaning a heightened percetion of your own heart rate, which may feel like pounding or racing. It may occur with regular rhythm, or with irregular rhythm (arrhythmia).
A defibrillator is a device used to deliver a shock to the heart to restore its normal rhythm.
In medical terms, the sleep wake cycle, also known as the circadian rhythm, describes an activity cycle that loops every 24 hours. Most organisms have this type of rhythm.

Cardiac arrhythmia refers to abnormal heart rhythm, as measured with an ECG. A "normal" rhythms is called a "Sinus Rhythm", as it originates in the Sinoatrial node of the heart. Any rhythm that originates elsewhere, or deviates from what is considered "normal" is an arrhythmia. There are many types of arrhythmia. On a cardiac monitor, if we see beats that are abnormal, we call the ectopy, or ectopic beats. But as far as a "term for arrhythmia"... that's the term: Arrhythmia.
The medical term for a slow heart rate is bradycardia. This can be a normal condition in some people, but it can also be a sign of an underlying medical issue that may need further evaluation and treatment.
