I had my pacemaker implant back in October 2018 so I'm now 3 years into life with one. Recently I was admitted to hospital after passing out after 5 minutes of steady cardio. When the paramedics came they said my heart was running fast and took me to rescucitation, they checked me and placed me in majors. After a few tests they found my pacemaker was fine and that the medication I was on was causing my tachycardia. They checked my electrolytes and saw magnesium was slow so started lumping a small dose into my body, after this my arm started to hurt and I panicked and my heart shot up to 212bpm, I was then placed back in resuscitation with defibrillator pads on my chest just in case. Once it had calmed down I was kept over night where I had multiple episodes of fast heart rates. They said it was the medication and that after it flushed it should be fine, the cardiologist also ran all my checks and said my heart is perfectly healthy.
In summary, after this I have been extremely anxious and depressed, I'm gaining weight and I'm paranoid that it is not my anxiety and that my heart is playing up. I'm scared to take antidepressants to help as the last medication I was on caused massive problems. I feel like I can't live my day to day and was wondering if anyone had something similar going on and if they had any advice as to how to cope with what I call cardiphobia.
Im only 23 and just want to start living my life again.
