Sinus arrhythmia

Sinus arrhythmia is a term used to describe the normal increase in heart rate that occurs during inspiration (when you breathe in). This is a natural process and can be more pronounced in children and athletes. Sinus arrhythmia is categorized into two types: Respiratory sinus arrhythmia and Non-respiratory sinus arrhythmia.

Types[edit | edit source]

Respiratory sinus arrhythmia[edit | edit source]

Respiratory sinus arrhythmia is a naturally occurring variation in heart rate that occurs during a breathing cycle. It is typically not a cause for concern.

Non-respiratory sinus arrhythmia[edit | edit source]

Non-respiratory sinus arrhythmia is less common and can be a sign of sickness, especially in older adults. It can be caused by conditions such as Sick sinus syndrome and Heart disease.

Causes[edit | edit source]

Sinus arrhythmia can be caused by various factors including:

Breathing - Changes in pressure in the chest related to breathing can affect heart rate.
Vagus nerve - This nerve plays a role in the body's automatic nervous system and can influence heart rate.
Heart disease - Certain conditions can cause sinus arrhythmia.

Diagnosis[edit | edit source]

Sinus arrhythmia is typically diagnosed through a Electrocardiogram (ECG). This test can measure the electrical activity of the heart and can help identify any irregularities.

Treatment[edit | edit source]

In most cases, sinus arrhythmia does not require treatment. However, if it is caused by an underlying condition, such as heart disease, treatment will be necessary.
