What could be the cause of ventricular fibrillation?

Question

Hello doctor,

My 29-year-old brother had a pacemaker implanted three years ago after surviving a sudden cardiac arrest. Doctors determined the cause of the cardiac arrest to be ventricular fibrillation. Last week, he received a shock from his pacemaker for the first time, exactly three years after his initial episode. My question is whether we can identify the root cause of his ventricular fibrillation. What is the best treatment for his condition?

Please suggest.

Hello,

Welcome to icliniq.com.

I understand your concern.

Coronary artery disease is the most common cause of ventricular fibrillation. Other causes include dilated cardiomyopathy or reduced heart function. What is his ejection fraction? A low ejection fraction, whether due to coronary artery disease or other factors, can lead to ventricular tachycardia and fibrillation. He should undergo angiography and an echocardiogram if he has not already. His electrolyte levels should also be checked, as imbalances can be a significant trigger for ventricular fibrillation.

In terms of treatment, he may require Amiodarone and various other medications based on his echocardiogram and angiography results. Typically, patients are prescribed antiplatelet medications such as Aspirin and Clopidogrel, along with an ACE (angiotensin-converting enzyme) inhibitor like Ramipril and Spironolactone, in addition to other necessary treatments.

Feel free to upload any of his reports so that I can provide a more informed opinion on the cause.

I hope this information helps, and please reach out if you have any further questions.

Thank you.
