I am 51 and I recently fainted for the first time in my life. Prior to fainting I was having blackouts near faints but ignored them because I assumed it was post Covid (spring 2022). I was sent to a cardiologist by my PCP and have also been admitted for chest pressure and pain. I had an ultrasound, it was normal. I had a heart Cath- no blockage. I had an MRI with no structural damage. I had an abnormal stress test and I have had several ECG, some normal some not. They recently implanted a loop recorder. My symptoms are dizzy often, short of breath often, near faints until I sit down when I feel it coming and V tach. My resting heartbeat is in low 50’s to high 40’s during the day and low 40’s at night. I am constantly tired with little to no energy and I used to exercise 5 days a week and have for years! Because all my tests are normal there is no urgency from the cardiologists. Can anyone relate or share similar condition?
