<prompt> Answer this question truthfullyWhat is the correlation between a pacemaker and electrocardiogram syndrome?  <response>: <reason> Electrocardiographic findings in pacemaker syndrome may include:prolonged PR interval VA conduction due to dyssynchrony between atria and ventricles andor AV dissociation. Single chamber ventricular pacemakers patients will have loss of AV synchrony Loss of AV synchrony due to AV block and rapid atrial pacing. Retrograde ventriculoatrial conduction Echo beats Other arrhythmias
