<bot>: Hi, welcome to Chat Doctor. Thanks for writing to us. Following may the cause of chest tightness, heart beat flutter and dizziness:1. Ischaemia and myocardial infarction.2. Paroxysmal supraventricular tachycardia(PSVT)3. Atrial fibrillation or flutter4. Indigestion and belching of abdomen5. Maniac disorders of the above-mentioned causes requires some underlying predisposing cause behind them. Only MI and PSVT can occur in an apparently normal subject at any time. Recurrency of such attacks is noticed in case of PSVT.Therefore, I would request you to go for an EKG whenever you experience such an attack. Then you can consult with your doctor with the EKG report in hand. Hope I have answered your query. Stay fit, good luck.
