What Is Sinus Arrhythmia?

An arrhythmia is an irregular change in the beating pattern of the heart. Sinus arrhythmia is what can be defined as the anxious state of the slowing down of the heart while breathing out or during expiration and increasing of the heart beat while inhaling or during inspiration. This abnormality could prove to be dangerous and if remained uncured might as well lead to the death of the patient.

So if you ask. 'What is sinus arrhythmia?' then there are other things too associated with it. However, a sinus arrhythmia certainly does not mean that an individual is suffering from an unwarranted disease, especially no heart disease as such. Many arrhythmias, particularly arrhythmia is found to take place in people who do not have the least symptom or inkling of any heart disease. In most of the cases, even if an arrhythmia is found to exist alongside a heart disease, it is in all likely possibility that the patient will likely die of the heart disease than of the arrhythmia, particularly sinus arrhythmia.

And a word of caution when you say,'What is sinus arrhythmia?', that sinus bradycardia is not the same as sinus arrhythmia. The symptoms of both the forms of heart-beat irregularities are divergent and the manifestations are different. Sinus arrhythmia affects the vagus nerve which is responsible for activating the nervous system-triggered parasympathetic input which regulates the heart beat. This systematic failure of the medulla oblongata results in the condition which is termed as sinus arrhythmia. To put it in simple words, the vagus nerve is left unstimulated resulting in the wrong signals to the heart and the subsequent decline in pitch of the heart rate. This is what is sinus arrhythmia.

Sinus arrhythmia is the most common form of arrhythmia that occurs in middle-aged adults. With the advent of age, the conditions of arrhythmia increases. The symptoms exuded include dizziness or light-headedness, feeling of breathlessness. Patients are almost certain that their heart skipped a beat and a feeling of abnormal giddiness overcomes them. Such symptoms are commonplace and should not be confused with the exceptional cases that occur in the course of your lifetime. But if you see a pattern in the irregularities, then the situation demands immediate concern or attention. I hope you got your answer to these question, 'What is sinus arrhythmia?'
