What is normal sinus rhythm?

Sinus rhythm is not something you might be guessing like the occurrence of sinusitis after regular intervals or with the change of season. It is totally a different concept. In medical terminology sinus rhythm means a normal beating of heart as measured by the readings of an electrocardiogram (ECG).

The heart has sinus nodes. Sinus node refers to a group of some consequential cells that are found in the atrium of your heart. The atrium is the exact location where electrical impulse takes place with the help of such sinus node. This cell that is sinus nodes perform different functions. The sinus node on the right atrium acts like a pacemaker to regulate the heart beat and at the same the sinus nodes or cells produce proper rhythm in the electrical impulse that causes your heart to pump blood at regular intervals.

What is normal sinus rhythm is the normal functioning of sinus node. The nodes which are the natural pacemaker of your heart has been naturally designed to generate electrical signals and conduct them throughout the muscular regions of your heart and stimulate it to contract and relax for pumping blood into arteries and Venecava.

If you observe the normal sinus rhythm in the readings of a ECG, you will find that there are five distinctive waves to identify the normal rhythm of heart. They are the letters like P, Q, R, S, and T. In a single beat of your heart they occur in a specific order which the doctor can study well and tell you whether your heart is functioning well or not.
