Sinus Arrhythmia

Sinus arrhythmia indicates irregularity in heart rhythm originating at the sinus node. It occurs as a normal variation in heart rate when your heart rate gets cycled with breathing. In this type, heart rate gets increased when you breathe in and slows down when you breathe out. The symptoms are chest pain, shortness of breath, tachycardia, and bradycardia. It is treated by taking antiarrhythmic drugs and having lifestyle changes.
