What is Normal Sinus Rhythm? - Normal Sinus Rhythm in a Nutshell

Meaning of what is normal sinus rhythm

An electrical impulse is generated by the sinus node, it moves through the right and left atrial muscles fabricating an electrical charge which could be seen in an electrocardiogram (ECG) by the p-wave. They continue their movement through specialized tissues known as atrioventricular node which carries electricity at a slower pace. There is a small pause (PR interval) which helps in the blood to be emptied into the ventricles from the atria, before the ventricle contracts to push the blood out into the body. This could be seen in the ECG as QRS complex of waves. The T-waves denotes the electrical changes in the ventricles while they are relaxing or resetting of the heart for the subsequent beat. This cycle repeats once again after a short gap.

In simple terms what is normal sinus rhythm. "It is an electrical pattern of the heart beat".

Normal sinus rhythms are found mostly in healthy heart. Heart runs on electrical impulses that stimulates it chambers (atria and ventricles) to contract and expand. With each heart beat the blood is pumped through out the body. Normal heart beat is between 60 and 100 beats per minute. There is no fixed heart rate; it may vary from a child to adult. A new born child's heart rate is 150 beats per minute, whereas a five year old has 100 beats per minute. In an adult it is 80 beats per minute. The S-A node or sinoatrial node is where the electrical impulse begins. This is otherwise known as the natural pacemaker of the heart. What is normal sinus rhythm detection methodology? This can be detected through ECG (Electrocardiogram). In a normal sinus rhythm the peaks are evenly placed.

What is normal sinus rhythm classification?

A normal heart rhythm with a fast heart rate is called sinus tachycardia. The impulses are normal bit the pace is faster. This is the case when you exercise or when you are excited.

A normal hearth rhythm with a slow heart rate is called sinus bradycardia. It is seen during medications such as beta blockers.
