Dear Joan,
Diastolic dysfunction is a type of heart dysfunction that has to do with the relaxation phase of the cardiac cycle. It is more common in older persons with a history of high blood pressure and other medical problems. PVCs stand for premature ventricular contractions which are benign 'extra beats'. You can find many posting on PVCs in the archives on this site.
I'm afraid I can't give you a very good second opinion on your symptoms with the limited information you have given me. I would guess that your blood pressure is low due to your medications and these may need to be adjusted. The shortness of breath and fatigue could be due to a number of different things including side-effects of your medications and your doctor will have to consider these factors in making adjustments.
Thank you for answering my question. I am a 50 year old women with a history of SVT's, palpitations, and mitral valve for 30 years. I have been on a treatment program of beta-blocker and lanoxin until 8/99 when I had two severe attacks of SVT. I was hospitalized twice in ICU and had cath's, EKG's, blood work ect. I went to the Cleveland Clinic 9/99 and had an excellent experience at this wonderful hospital. I had complete testing and was told I needed an ablation and did so 10/99. I did very well except for high pressures in my heart which needed to be addressed with medication. I went on a treatment of veseretic 5mg in AM & PM. I was retaining fluid and also having difficulty with shortness of breath. What I am not sure of is this diagnosis of left ventricular diastolic dysfunction from my cardiologist in NJ and why it showed up now. Should I be very concerned about this? My cardiologist in Cleveland Clinic said my heart was in good condition after the ablation and never mentioned anything about this ventricle at my last checkup there in 12/99. Please advise me of what questions I should ask and where do I go from here?
