What is the normal heart rhythm (sinus rhythm)?
First, a normal sinus rhythm refers to both a regular heartbeat and rhythm. A normal sinus rhythm is deemed to be anywhere from 60 to 100 beats per minute.
Sinus arrhythmia is a term used to describe the normal increase in a person’s heart rate that occurs from regular breathing activity; sinus tachycardia is a term for the fast uptick in a person’s heartbeat rate as a result of exercise or stimulants.
When your sinus rhythm isn’t functioning in accordance with this scale, it is deemed an arrhythmia – an abnormal heart rhythm. This sounds scarier than it may be; a heart arrhythmia could be a result of many things and is a normal condition to have.
