Chest pain on exertion for last 2 years. Palpitations whilst resting. Occasional dizzy spells. Tests performed: 7 ECG's, all reported as normal, bar one which showed a possible ectopic Echo-cardiogram, reported as normal ECG treadmill test, reported as normal Coronary CT Angiogram, reported as normal I'm 21, male, no known health problems. Resting 57bpm, BP 130/80 Is it possible for all of the above tests to miss something cardiac? Mr doctors have just dismissed it as anxiety now...
