Ventricular Fibrillation and Mitral Valve Prolapse Risks - Cardiology

Arrhythmia-related issues?

---

Hello, Doctor: I would like to ask if mitral valve prolapse can lead to the occurrence of ventricular fibrillation.
If so, what is the likelihood? Additionally, what is idiopathic ventricular fibrillation? Where can I find related information? It seems that there is very little information on this topic.
I apologize for the lengthy inquiry.
Thank you.
In 2008, Dr.
A at a hospital in northern Taiwan mentioned that I might have mitral valve prolapse.
Since I had no obvious symptoms and no significant issues, treatment was not necessary, but I was prescribed antiarrhythmic medication.
However, after taking the medication, my heart rate dropped below 40 beats per minute, and my blood pressure fell to around 60/40, so I stopped taking it after two doses.

In 2013, I was diagnosed with narcolepsy at a hospital in central Taiwan and began taking modafinil and methylphenidate.
A year later (2014), Dr.
B suggested I consult Dr.
C, the head of cardiology at the same hospital, to confirm whether I had any heart problems, which would help in adjusting my medication dosage.
After seeing the cardiologist, my heart was found to be normal, but I underwent a tilt table test, which resulted in cardioinhibitory response, with EKG recording showing asystole.
I received CPR for 10 seconds and then regained spontaneous circulation.
During a follow-up, Dr.
C informed me that my condition is very rare both domestically and internationally, and he was unsure of the cause, so he would look into the literature and call me for a follow-up.
After six months, I underwent a comprehensive health check-up at my own expense.
During a painless colonoscopy and gastroscopy under general anesthesia, there were cardiac issues, and I woke up two and a half hours later feeling weak.
The nurse advised me to be particularly cautious before and after anesthesia.
When I reviewed the report and asked Dr.
D at the health check-up center about this, I was referred back to Dr.
C for consultation.
I was later informed that it was a vagal reflex - cardioinhibitory type, and the cardiology team decided that I needed a pacemaker, as it was difficult to manage with medication.
They mentioned hospitalization and arranged for Dr.
E to perform a cardiac catheterization.
After being hospitalized, Dr.
E informed me that all my EKGs and echocardiograms were normal, and there was no need for a pacemaker.
However, during the cardiac catheterization the next day, I suddenly experienced ventricular fibrillation.
I received CPR followed by defibrillation, and after about a minute of CPR, I regained consciousness but was unable to speak, with weakness on my left side and spasms on my right side.
After consulting with a neurologist, it was suspected that I might have had a stroke, and I underwent a CT scan and was sent to the intensive care unit.
A few hours later, another Dr.
F was urgently contacted to perform an implantable cardioverter-defibrillator surgery.
Throughout the day, Dr.
E and Dr.
F frequently checked on my condition in the ICU but only mentioned that I had a lethal arrhythmia that was malignant and easily triggered, possibly due to genetic mutations or congenital issues.
The cardiologists also discussed whether my narcolepsy could be a symptom generated by the heart, as I had averaged over 12 hours of sleep daily since childhood and would suddenly fall asleep during the day, although it was suspected that this might be a form of brief unconsciousness.
I was hospitalized for six days, and everything happened so quickly.
It has been a month since my discharge, and I have started cardiac rehabilitation.
However, I am still very confused as to why I am the only one in my family with heart problems, especially since the episodes occurred without any symptoms or warning signs, and I felt no discomfort.
Additionally, the defibrillation was extremely painful, and I had significant burns on my chest.
The entire process was intense, and I was startled awake at home after discharge due to the memory of the shock.
Given my lack of understanding of this condition, I fear that I might not wake up the next moment, which makes me reluctant to sleep for long periods.
I also have a fear of the defibrillation experience.
Since my attending physician is abroad and the psychologist will not return until the end of August, I am currently unable to discuss this.
At this stage, I need to seek help to understand and alleviate my fears.
