Arrhythmia is a medical condition that affects the rhythm of the heartbeat. It is estimated that between 2 and 3 million people in the United States are affected by arrhythmia. However, the exact number of people living with arrhythmia is difficult to determine due to underdiagnosis and misdiagnosis.
Causes of Arrhythmia
Arrhythmia can be caused by a variety of factors including physical activity, stress, diet, and certain medications. It can also be caused by underlying medical conditions such as heart disease, thyroid disease, and diabetes. In some cases, arrhythmia may be caused by genetic factors.
Symptoms of Arrhythmia
The most common symptom of arrhythmia is an irregular heartbeat. Other symptoms may include fatigue, chest pain, shortness of breath, dizziness, and fainting.
Diagnosis of Arrhythmia
A diagnosis of arrhythmia is usually made through an electrocardiogram (ECG). An ECG is a test that records the electrical activity of the heart and can help detect any abnormalities in the heart's rhythm.
Treatment of Arrhythmia
Treatment for arrhythmia may include lifestyle modifications, medications, or an implantable cardioverter-defibrillator (ICD). Lifestyle modifications may include avoiding stimulants such as caffeine and alcohol, eating a healthy diet, and exercising regularly. Medications can help regulate the heart rhythm, while an ICD can detect abnormal heart rhythms and deliver a shock to restore normal rhythm.
Outlook
The outlook for people with arrhythmia depends on the cause and severity of the condition. In many cases, lifestyle modifications and medications can help manage the condition and reduce the risk of complications. In more serious cases, an ICD may be necessary to prevent serious heart complications.
