Question Title: Could i possibly have mitro valve prolapse?

sudden accelerated heartbeat (260 bpm) from no obvious stimulus while
sitting down that lasted for approximately five minutes. this only
happens very occasionally, and sometimes when i bend over and blood
rushes back up. and sometimes i get pains in the lower left side of
my rib cage (just under the pectoral muscle). not a sharp pain more
of a tiredish feeling and a little nagging

regards Grant

Dear Grant

MVP can cause palpitations, but rarely. It is used by doctors and patients to explain palpitations far more often than it should be.

A heart rate of 260 is very concerning, if accurate. This could be potentially life-threatening. You should make sure that you are evaluated by a cardiologist.

I hope this is useful. Feel free to write back. I wish you the best of luck.

If you would like to set up an appointment with one of our cardiologists here at the Cleveland Clinic please feel free to call 1-800-CCF-CARE.
