A Brief note on Heart Rhythm and Arrhythmias
The signal then travels through the atria to the cardiac muscle between 60 and 100 beats per minute (bpm) while you're resting. If the sinus rhythm is slower than 60 bpm, then it's called sinus bradycardia. In a normal cardiac rhythm, a small cluster of cells at the sinus node sends out an electrical signal. The signal then travels through the atria to the cardiac muscle then passes into the ventricles, causing them to contract.
