we are here to help you. from the way you are describing it seems either you had an arrhythmia that time or you had angina pain. since your blood pressure and heart rate are in normal ranges without medicines you should avoid any medicines at this time. i would recommend for you a treadmill test that is a stress test to rule out any angina on exertion. if that comes out to be normal then you would need to go for holter monitoring. take antacid drug like omeprazole for this purpose as this would help you in fighting with acidity as a cause of chest pain. however acidity is very unlikely to be a cause for that. i hope it helps you. revert back after the tests to a cardiologist online --> <link>
