Hello
Welcome to healthcare magic.
If these symptoms are related to meal times then it could be gaseous distention and not heart condition.But if it isn't related to food and you feel breathless or have
high Bp then it could be
arrhythmia of heart.please get yourself examined by your doctor to relieve any doubts.
Til then you should try to walk few min after eating, drink plenty of water and may benefit with
antacid tablet.
Thanks
