Causes of Low Heart Rate or Heart Arrhythmia

Low heart rate causes, or arrhythmia may not cause any signs or symptoms. In fact, your doctor might find you have an arrhythmia before you do, during a routine examination. Noticeable signs and symptoms don’t necessarily mean you have a serious problem, however. Noticeable arrhythmia symptoms may include:

• A fluttering in your chest
• A racing heartbeat (tachycardia)
• A slow heartbeat (bradycardia)
• Chest pain
• Shortness of breath
• Lightheadedness or dizziness
• Sweating
• Fainting (syncope) or near fainting
