7Possible Complications
Sinus arrhythmias is mostly a benign condition. Therefore, complications are quite rare. In fact, this condition can be undetectable because it does not trigger any noticeable problems or symptoms. If the condition occurs at the same time with sinus tachycardia or bradycardia, the combination would lead to several complications. Fast heartbeats can trigger chest pain, lightheadedness, and heart palpitations. Slow heartbeats would lead to fainting, shortness of breath, and dizziness. [7]
