The second time I experienced SVT was in 2007, again my Dr gave me
Lanoxin.
Lanoxin was only prescribed when ever i have SVT. This 2009, I had several SVTs. In Sept 2009, my Dr. suggested to hv my regular ECG, CBC and my first time to undergo a 2D Echo with Doppler. My BP is 90/60. All ok, except for my low rbc ct in CBC. My Dr told me that low rbc cause lack of oxygen that is the reason i had SVT. She prescribed Ferrous Sulfates as source of my iron for blood oxygen.
