@domiha Not insignificant!
You deserve to have your options thoroughly explained and every one of your questions answered. Not the type to press your doctor? Never too late to start. It’s their job! I find understanding medical problems and their potential remedy comforting. Being in the dark is stressful!
I have never had AFib but I do have a different arrhythmia called NSVT- non-sustained ventricular tachycardia- heart beating too fast which can be deadly.
To answer your question, I receive a phone call from the staff( a PA) of my EP’s office when they are notified by the monitoring staff of any heartbeat other than normal. I am asked if I felt anything. I answer no because I have never fainted and have never even felt faint. I am told that being asymptomatic is likely the result of having an otherwise healthy heart with a normal ejection fraction and no blockages based on a myriad of tests I’ve had. Because ventricular tachycardia can be fatal, I not only have a loop recorder, but also a ICD (defibrillator) implanted as an insurance policy. Defibrillators can have two functions: shock the heart back into rhythm if it stops and also a pacemaker function that controls how fast or slowly your heart beats. Depending on the rhythm noted by the recorder, my medication can be tweaked.
Hope this helps. You should consider making an appointment for the purpose of your physician (an EP at a very good hospital) devoting the time for you to learn your options in a relaxed setting without rushing. If your doctor is unwilling, ditch him or her for someone better. It’s work to organize all this, but worth the peace of mind you’ll get in return.
