Sinus nodes (sa nodes)
When the heart is functioning properly the sinus node controls the firing of action potential that contract the heart. When the sinus node dominates the heart will contract in a synchronized and effective rhythm This is called sinus rhythm.

Sinus nodes (sa nodes)
Sinus bradycardia is basically a decreased heart rate. It originates from the sinus node and will be under 60 beats per minute.
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.
Sinus rhythm refers to a heart rhythm that is controlled by the depolarisation of the sinoatrial node. You can also have focal ectopic rhythms where random areas of the heart depolarise first and you can have supraventricular rhythms.

Atrial fibrillation (afib) is an irregular heart rhythm where the upper chambers of the heart beat chaotically and out of sync with the lower chambers. Sinus rhythm is a normal heart rhythm where the heart beats in a regular, coordinated pattern. Key differences include the irregularity of afib versus the regularity of sinus rhythm, as well as the potential for symptoms and complications associated with afib.
