Today something very odd happened! I was say down talking, when it pretty much felt like my heart was t beating for about 5-10 seconds, got very light headed, losing sight and sound as if I was going to faint, then a very strong "thud" and feeling very hot all over. As a one off mw doesn't think I should be concerned, but to keep an eye. I'm seeing the cardiologist again in 4 weeks so will explain it to him them, it was just so odd. Anyone else experienced this???
