Hi,
Welcome to icliniq.com.
- Implantable defibrillators are implanted to terminate an episode of atrial arrhythmia. AFib (atrial fibrillation) is also a type of atrial arrhythmia.
- The ICD not only provides treatment for atrial arrhythmias, but also provides treatment for ventricular arrhythmias, as well as rate-responsive dual chamber pacing for the treatment of bradycardia.
- The pacing attempts to gain control over the arrhythmia by interrupting the pathway of the atrial arrhythmia and uses low energy pacing, which is usually goes unnoticed by the patient.
- In cases when ATP (antitachycardia pacing) is successful, the patient may not even be aware that they have had an arrhythmia, until their device follow-up.
- So, the answer for your question is ICD cannot cause atrial fibrillation until and unless it is implanted incorrectly; rather it will terminate an episode of atrial fibrillation automatically.
