question: I was diagnosed with mitrol valve prolapse about 30 years ago and my cardiologist told me to forget I have it.  Recently I have been experiencing a rapid heart beat at various times during the day.  It comes and quickly goes away.  I have low blood pressure.  I am under a considerable amount of stress.  I have been attributing it to that but am wondering if I should contact my internist/cardiologist for an appt.  Just had my yearly physical and ekg. 6 months ago and everything was normal
