Hello Dr, 41 year old, non-smoker, 1-5 units of alcohol a week, active, no other health issues. Family history of heart problems (Hypertrophic cardiomyopathy ), have been checked and do not have it, although have a slight thickening of arterial knuckle which gets monitored. I m getting what feels like pulses or faint flutters from my oesophagus region to the top of my sternum region, these symptoms are infrequent during the day to sometimes non-existent, but at night the symptoms only occur when laid on my back or on my left side (they disappear when I m lying on my right side?) and feel more constant with a heart beat ie pulses at a constant rate. Occasionally have slight breathlessness since this has started 1 week ago. Now I ve had a slight upset stomach (although not constipated I ve not been regular) the last week and the symptoms do seem to be more present when I have heavy feeling in my stomach and then subside once I pass wind. Is the pulses/flutter linked to this and could be a blockage and wind not escaping? Or something else?
