ecg interpretation

recently had an ecg, interpretation reads as follows:
12SL - Interpretation:
           Sinus rythm with frequent, premature ventricular complexes and possible premature atrial
           complexes with aberrant conduction.  Otherwise normal ecg.

What exactly does this mean?

A Premature Ventricular Contraction or Complex (PVC), also known as a ventricular premature beat is a relatively common event where the heartbeat is initiated by the heart ventricles rather than by the sinoatrial node (right atria), the normal heartbeat initiator. The electrical events of the heart detected by the electrocardiogram allow a PVC to be easily disntinguished from a normal heart beat.

A short PR wave shown on an EKG would be an early activation of the left ventricle for contractions.  Can be due to a short pathway and extra pathway...aberent conduction.

It should be made clear that a computerized analysis (12 SL cmputer software) is not a substitute for physician interpretation. There are two reasons for this. First, statements of accuracy need to be viewed from a statistical perspective. Although accuracy levels may be high, outliers can and will exist. Second, a computer does not have the ability to include the entire clinical picture of the patient. A person with organic heart disease may exhibit an EKG within normal limits. Conversely, a normal individual may have an abnormal appearing EKG. The EKG, therefore, must always be reviewed in light of the surrounding clinical circumstances.
