Hello and thank you for using HCM. I carefully read you question and I understand your concern.I will try to explain you something. There are different reasons that might cause increased heart beats. Simple physical or emotional stress, caffeine products might cause increased heart frequency so its mandatory to avoid them. After eating, our metabolism increases so it might be normal to have slight high frequencies for a while. Or it may be another problem. When you eat, the abdominal distention rises up the diaphragm and in a secondary way might trigger the heart for higher frequencies. A simple gastro-ezofageal reflux or the food that comes back from stomach to esophagus all saw might be the cause. There are different pathology s like anemia, thyroid gland problems like hyperthyroidism that might be the cause of fast heart beats. When you experience a high frequency, it might be normal to experience palpitation, chest discomfort, pressure and breathing difficulties. So, if I was your treating doctor, as you allays connect this symptoms with eating i will recommend a gastroenterologist consult, a fibrous-gastroscopi maybe to exclude any problem like re-flux, diaphragmatic hernia ect. After this I will recommend an electrocardiogram, a cardiac echo-cardiography and of course a rhythm holter monitoring for 24 h. This is necessary to have a full view of your mean frequencies during day and night. After these, a full blood chek up to exclude anemia or thyroid problems as you want to have a baby soon. Doing this examinations helps us understand if it is necessary to treat this high frequencies or not. You should not be worried, because this is nothing serious. Hope I was helpful. Wish you good health. Best regards.
