An echo found heart murmer that the cardiologist said was otherwise undetectable. ekg and stess test ok. dr said not to worry its normal. correct?

Probably, yes!: Echo can detect more than what your doctors need to know... The results can be misleading and falsely positive. You are probably ok...

Echo: What your doctor probably told you was that you had a mild valve abnormality of no physiologic significance, not a heart murmur. A murmur is just noise. Sometimes serious problems cause a murmur many times a murmur is caused by normal flow. Patients often misctranslate what the dr. Tells them.
