Abnormal: The study showed numerous abnormalities including bradycardia, mild ventricular irritability, marked atrial irritability including a run(?duration) of supraventricular tachycardia and 2 dropped beats that may have been nonconducted atrial premature beats or transient AV heart block which is more serious. I strongly recommend that you consult a cardiologist.
