Can I exercise?

I am a 40 year old male who has suffered from pvc's and PAC's for 20 years.  BP and cholesterol ok, both grandparents died before 50 of heart disease. I am 6 ft 4 weighing 215 lbs.  Athletic all my life with the exception of the last few because of palpitations.  Can you translate some of these readings for me and tell me if I have anything to worry about.  Can I still exercise regularly?
1.  24 hour holter negative with the exception of rare supraventicular ectopy totalling 900 beats.
2.  Stress test, Functional capacity, normal, HR response to exercise, normal.  Everything normal with exception of SVT during recovery of 250BPM, 4 beats of V-Tach, and 2 vent. couplets, few PVC's, and frequent PAC's.  Normal exercise tolerance.
3.  Echo-  Left Atrial Diam-4.1, aortic root-4.1, post wall thickness, 1.0, fractional shortening, 25%, LVID kin Diastole-5.4, LVID in Systole-4.1, septal thickness, 1.3.
Normal LV chamber size with mildly increased thickness in the septum, sigmoid appearing, and mildly enlarged left atrial size.
Bi-Leaflet mitral valve prolapse, mild in nature, with mildly enlarged left atrial size.
Grossly normal appearing tri-leaflet aortic valve, normal aortic root, normal right ventricle and function, normal tricuspid, normal right atrium, normal pulmonic valve, no pericardial effusion.  Normal flow within LV cavity, normal flow across the aortic, tricuspid, and pulmonic valve.  Mild mitral regurgitation.
IMPRESSION- Using 2D echo, Normal LV chamber size with mildly increased thickness, mild MVP of both leaflets with mild regurgitation.

Please help!

Drew,

I can't tell you any thing specifically about exercise without personally reviewing your full history and examining you.

The gross interpretation of all of your studied are that you have essentially a normal heart, and have occasional extra heart beats which is a normal finding.

There is nothing in your history that you post here that would cause me concern with respect to you having a normal fitness regimen.

hope this helps.

Did your doctor tell you that you can exercise?

Dr. said it was ok to exercise, but when I went into SVT after exercise, it scared the daylights out of me.  They had me lie down, bear down as if to have a bowel movement, and the cardiologist massaged my carotid in my neck.  In a matter of seconds, my heart rate went back down.  Also, I was concerned about the 4 beats of ventricular tachycardia during exercise.  Everything I read tells me that type of arrythmia can be deadly.  That's why I am so fearful.

I see. I think you should speak to your doctor and address those specific fears. It seems a shame to give up exercise if it's not necessary. It's one of the things that diminishes stress in people.  Maybe you two, together, could work out a program that gradually gets you back into working out, without pushing yourself too hard at first? I suspect your doctor would love to see you feel able to exercise again.
Good luck to you.

4 beats would not be vt, it would be NSVT (Non-sustained ventricular tachycardia) which is not lifethreatning and in a normal heart wont turn into VT, so try and help yourself relax a little, and ask your cardiologist to explain the findings to you so you can understand better
