If you have a family history of arrhythmia, it's important to be aware of the symptoms and to get your heart checked regularly. According to the Mayo Clinic, if you have a family history of arrhythmia, you may be at an increased risk of developing the condition. However, there is no specific guideline on how often you should get your heart checked if you have a family history of arrhythmia.
It's recommended that you talk to your doctor about your family history and any symptoms you may be experiencing. Your doctor may recommend that you undergo an electrocardiogram (ECG) or other tests to check your heart's rhythm. If you experience any symptoms of arrhythmia, such as a fluttering heartbeat, rapid heartbeat, chest pain, weakness, fatigue, or low blood pressure, it's important to seek medical attention.
