Due to waking up in night yesterday with nausea and chest heaviness. I did ecg and trop t yesterday. Reports are normal. Trop t was negative with 0.6 reading. Gas issue was also there i think, as i was burping. I am always concerned of cardiac issue. Now a days i feel imbalanced, feeling of falling down, discomfort in chest. Echo and tmt were done in second week of april and were normal. I am not able to figure it out whether it is gastric or heart issue. I can walk, run easily. Just now ran 1 kms. Pl guide.
