<s>[INST] Had some irregular hearbeats and dull ache in middle of chest. Had ekg done and blood pressure check and all was good. Few day later get the dull ache again. Seems like thats all I can think about. Should I go to er or wait and check with family doctor? [/INST] Hello! Welcome and thank you for asking on Chat Doctor! Regarding your concern, I would recommend performing further tests to investigate for the possible cause of your symptoms: - an ambulatory 24-48 hours ECG monitoring is necessary to examine your heart rhythm trends during the day.- a cardiac stress tests is needed to exclude possible coronary artery disease which could lead to chest pain - a chest X-ray study to exclude possible lung disease- a fibrogastroscopy to exclude possible gastroesophageal reflux or gastritis, which could also be the cause of chest pain. Hope to have been helpful! Best wishes,  </s>
