Atrial Fibrillation vs. Supraventricular Tachycardia: What You Should Know
Atrial Fibrillation (AFib) and Supraventricular Tachycardia (SVT) are common types of heart arrhythmias. They have similar symptoms, including a fast or irregular heartbeat, shortness of breath, and chest pain. However, they are two distinct medical conditions.
Atrial Fibrillation is a condition in which the upper chambers of the heart (the atria) beat irregularly. This can cause the heart to beat too fast (tachycardia) or too slow (bradycardia). AFib is often associated with other medical conditions, such as high blood pressure, heart disease, diabetes, and obesity.
Supraventricular Tachycardia is a type of fast heart rate that starts in the upper chambers of the heart. SVT can also occur in people with other heart conditions, such as Wolff-Parkinson-White syndrome.
Comparison Table
| Feature | Atrial Fibrillation | Supraventricular Tachycardia |
|---|---|---|
| Location of arrhythmia | Upper chambers of the heart (atria) | Upper chambers of the heart (atria) |
| Heart rate | Usually fast (tachycardia), but can also be slow (bradycardia) | Fast (tachycardia) |
| Symptoms | Fast or irregular heartbeat, shortness of breath, chest pain, dizziness, lightheadedness | Fast or irregular heartbeat, shortness of breath, chest pain, dizziness, lightheadedness |
| Associated conditions | High blood pressure, heart disease, diabetes, obesity | Wolff-Parkinson-White syndrome |
| Treatment | Medications, surgery, lifestyle changes | Medications, surgery, lifestyle changes |
When to See a Doctor
If you experience any of the symptoms of AFib or SVT, you should see a doctor right away. This is especially important if you have other heart conditions or you are taking any medications that can affect your heart rate.
Treatment
The treatment for AFib and SVT depends on the severity of the condition and the underlying medical conditions. Medications, surgery, and lifestyle changes can all be used to manage these arrhythmias.
Outlook
The outlook for people with AFib and SVT is generally good. However, it is important to follow your doctor's instructions to manage your condition and prevent serious complications.
