Non-specific: What you're describing is rather non-specific, that is, you'd have to combine the EKG findings with a thorough history and physical examination by your primary physician. They may want to, then, refer you to a cardiologist or cardiac electrophysiologist to see if the findings are significant. Call 911 if you pass out, have chest pain, severe dizziness, or sudden onset shortness of breath.
