I’ve been battling a range of symptoms for a while now always after eating and hope someone might be able to put my mind at rest that theyre not heart related. I have short episodes usually 10-30mins whereby I struggle to catch a breath, have a restriction in my chest like a band/belt, dizziness, suddenly very cold, tingling in face and hands and lips go slightly blue, heart rate falls to 50bpm. On walking heart rate rises to 145bpm despite the walk being leisurely, resting heart rate sits between 65-95. Im asthmatic and have had investigations for gastro and allergies none of which have shed any light on symptoms. Should I push to see a cardiologist?
