I was diagnosed with MVP and PVC's after having severe anxiety attacks. My cardiologist wasn't very helpful and told me, "it's not a big deal and to just get over it, that I would be fine." I'm still worried that my heart will just stop so I'm to scared

Mitral valve anxiety. While clinicians often diagnose the "mitral valve prolapse syndrome" with palpitations, anxiety, and other symptoms, in truth the association between the valve and the symptoms is not at all certain in most cases. If you truly have an abnormal mitral valve, as diagnosed by echo and interpreted by an expert, then a cardiologist can give you advice. In most cases no treatment is needed.
