Was diagnoised with angina and right bundle block around 25/30 years ago.  Am 52 now and whenever i walk a short distance also am suffering from breathlessness.  what could this be ?Also, the ECG, and echo results are normal - what could i be suffering from?
Sir, breathlessness on exertion with a history of angina is a strong indication of underlying heart disease particularly in your case after ruling out other common causes like decreased hemoglobin and other common condition. A treadmill stress test will help you evaluate the same. Normal echo and ECG doesn't rule out an underlying heart condition as they are taken at rest.  Hoping I could help. Regards Chat Doctor.
