So I am at a holiday park at the moment and went for a walk with hubby and kids. We were just playing some games and all of a sudden I got this palpation (I've had them all day) and then after the palpation my heart stopped for a few seconds and I went really faint and vision blurred and then my heart started pounding. I have been diagnosed with SVT. But I've had SVT symptoms since I was a child. It's just jay the past 2 years they have been made worse. I am convinced something is making these attacks worse but bloods always come back normal. I'm really scared. I've had numerous symptoms for 2 years and they are ruining my life I can't do anything any more. Could my heart really have stopped. Could I have nearly died? Doctors don't believe there is nothing wrong with me but I believe there is as these have been made worse recently. I have silent reflux as well but stopped taking the tabs now.
