Hello Doctor, I have been dx in the past a having a heart murmur as a child and was not a worry! Now, 40years later, after several symptoms placed as anxiety?!?, and an echo in 1989, I have a redundant mitral valve disorder with effusion. Not much happened since the past dx except periodic chest pain, breathlessness,palpatations. Now in 1999, I have experienced flip-flopping of my heart, beat stopping, overbeats, and admitted to the er for a possible heart attack..Not! However, their were inverted beats noticed and told me that I probably had a prior heart attack or mild stroke. However, the flip-flops can last a month with nothing in between and now again, flip-flops..I know I should be evaluated by a cardiologist but my primary feels he can monitor my problems...Do you think I should follow-up with a cardiologist? What are flip-flops? E
