infrequent pvcs during exercise stress test

[Slamtime]

Just recently had exercise stress test, was told by my doctor results were fine. { family doctor not cardiologist  }  read report review of ECG demonstrated no significant ST or T-WAVE changes with exercise into recovery. Infrequent PVCs were noted during study. Patient achieved total work load of 13.4 Mets. Patient experienced no chest pain with exercises or into recovery. Normal St segment and hemodynamic response to symptom- limited exercise. what I am worried about is the infrequent PVCs ,  any thought's on that. Some information on me ,65 year old male type 2 diabetes well controlled { take low dose of metformin.} walk 4 to 5 miles a day. reasonably good health for my age.
