Probably normal: Pvc's are common and assuming you had holter monitoring more than half would have asymptomatic pvc's. If you use albuterol for asthma, it can cause palpitations and pvc's by increasing your heart rate. Stress echo at your age is being done as an added test to evaluate for any structural abnormality (eg mitral valve) or hypertrophy of left ventricle, may unmask inducible arrhythmia.

CAD: Coronary artery disease is one of the possible causes of pvc, and a stress test may be indicated to screen for this. Watching to see how your arrhythmia behaves during exercise is also helpful prognostically.
