Hi all.
over the last year or so I have been getting increasingly short of breath especially when walking, going up hill/stairs etc, wheezing when laughing a lot, crackling in throat when laying down and wheezing (not every time though), chest tightness and pain and puffy legs and ankles. My maternal grandparents died of heart disease, my dad died from a sudden heart attack 17 years ago and my brother has an enlarged heart so naturally I’m worried I may have heart failure or something. I had an ECG at the doctors yesterday and my results seem to point to something wrong. I have an appointment with a doctor tomorrow but would like to be fully prepared so can anyone help and what I should be asking etc? Pic attached of ecg. Thank you
