Sinus arrhythmia can heal on its own because it is a functional arrhythmia with no organic heart disease. It is commonly seen in young adults during their growth and development stages who frequently stay up late or have insufficient sleep, and in women going through menopause due to autonomic nervous dysfunction. The arrhythmia can self-resolve through rest, ensuring adequate sleep, and regulating the autonomic nervous dysfunction. It is also somewhat related to breathing. This type of arrhythmia generally does not require treatment with anti-arrhythmic drugs. It is important to rest, ensure sufficient sleep, and avoid drinking strong tea or coffee.
