Has anyone ever had this sensation......I will try and explain but this will sound *crazy*, but it's the best way I can explain so bear with me.... Ok so I can be sitting or standing anywhere at anytime, and SUDDENLY feel like i have instantly blacked out..for a brief second, all the while I have this sudden pause and almost painful (but not really) sensation in my chest. It's almost like I was "unplugged" from an electrical source or something... so wierd and hard to explain, I have PVC's and PAC's ALOT.daily...I have been having these for 15 years...but the sensations and frequency has changed and so they are beginning to scare the "Blank" out of me. My cardiologist in the past have all brushed me off after all the I have had stress tests, ECG, EKG, Thyroid test, Electrolyte tests..and everything seems "normal" what ever "normal" is. My currently cardiologist put me on metoprolol 12.5 mg as I am very bradycardic, sitting up and talking at 48 BPM and do not have BP issues, and says that this medication is more for my symptoms and not my extra beats...and that these are not harmful, no matter how I am feeling and they are completely begnin and are not going away, and just continue to reassure my self that I have been "checked" out. I am a single mom of two children 15 and 7 and I have alot of life to live yet, and i need help or insight on your thoughts are suggestions. Also, the cardiologist said to try magnesium 400mg daily... Should I just come off this metoprolol and try mag, and just deal with it?? or am I overlooking something else or another medical opinion........ ugh so scared and frustrated. So any professional and friendly advice would be much appreciated! xo J
