 Sinus arrhythmia is a common, harmless condition that is not necessarily dangerous; however, it should be evaluated if accompanied by other signs of heart problems. Sinus arrhythmia is a variation in normal sinus rhythm. It is a common, harmless condition, seen more often in children and young adults, and affects both males and females equally. It is not necessarily dangerous. However, if a sinus arrhythmia is accompanied by other signs of heart problems, such as a heart flutter, pain in the chest, fatigue, dyspnea on exertion, and excessive perspiration, a medical evaluation is required to determine the underlying disease. What is sinus arrhythmia?The heart is a vital organ that works incredibly hard, beating more than one lakh times per day to fulfill the critical requirement of the distribution of oxygen and nutrients throughout the body. The term sinus arrhythmia is defined in two terms.
Normally, electrical impulses initiate in the sinoatrial node, which causes the atrium to contract, thus forcing the blood down to the ventricles (lower chamber of the heart). This process is repeated 60 to 100 times a minute (a normal heart rate range). A normal heart rhythm is a sinus rhythm found in healthy people, whereas sinus arrhythmia is an irregular heart rhythm that originates in the sinus node. 3 characteristics of sinus arrhythmia on electrocardiography
8 types of arrhythmias
7 symptoms of sinus arrhythmiaSinus arrhythmia is usually asymptomatic, but if symptoms occur, they may include:
QUESTIONIn the U.S., 1 in every 4 deaths is caused by heart disease. See AnswerHow is an arrhythmia diagnosed?Arrhythmia is often diagnosed accidentally during a routine examination or evaluation of some other medical condition. After a thorough physical examination and history taking, a cardiologist (heart specialist) may recommend certain diagnostic tests to confirm the presence of arrhythmia and evaluate its causes.

Researchers suspect that a connection between the heart, lungs, and vascular system may play a role. In older individuals, a sinus arrhythmia can occur as a result of heart disease or another heart condition.
What is the meaning of sinus arrhythmia?Sinus arrhythmia is a kind of arrhythmia (abnormal heart rhythm). For the most common type of sinus arrhythmia, the time between heartbeats can be slightly shorter or longer depending on whether you're breathing in or out. Your heart rate increases when you breathe in and slows down when you breathe out.
Does normal sinus rhythm mean healthy heart?Normal sinus rhythm (NSR) is the rhythm that originates from the sinus node and describes the characteristic rhythm of the healthy human heart. The rate in NSR is generally regular but will vary depending on autonomic inputs into the sinus node.
What is the most important difference between normal sinus rhythm and sinus arrhythmia?Normal sinus rhythm is a regular rhythm that occurs in generally healthy people. Sinus arrhythmia is an irregularity in the heart rhythm that originates at the sinus node.
