Arrhythmia - Signs, Symptoms, and Complications - Signs, Symptoms, and Complications

An arrhythmia may not cause any obvious Signs or symptoms. You may notice something that occurs only occasionally, or your symptoms may become more frequent over time. Keep track of when and how often arrhythmia occurs, what you feel, and whether these things change over time. They are all important clues your doctor can use. If left untreated, arrhythmia can lead to life-threatening complications such as stroke, heart failure, or sudden cardiac arrest.
