What is the prognosis for lafb with frequent minor arrhythmia (pvcs, unspecified tachycardia) and minor lvh secondary athletic training?

I consider the presence of LAFB in combination with frequent PVC's, runs of tachycardia &LVH as potentially quite concerning. You'd be best served by consulting a cardiologist with a specialty in electrophysiology for thorough evaluation, advice and follow-up care. An important question is whether your ventricular irritability is benign or warrants treatment. Treadmill stress testing is important.
