The normal heart rhythm is ''sinus rhythm''. That means that the rhythm has its origin in the sinus node, the heart's fastest physiological impulse generator.

Heart rhythms which are not sinus rhythm are [[arrhythmias]].
Heart rhythms which are not sinus rhythm are [[arrhythmias]]. If the heart rate exceeds 100 bpm, the [[Arrhythmias#Tachyarrhythmias|tachcyardia flow chart]] should be followed.
