Pacemaker Syndrome is a clinical entity, most frequently produced by an inadequate AV synchrony, in which the phenomenom of retrograde AV conduction plays a major role, generally in patients with a single-chamber pacemaker with a WI stimulation mode. Main symptoms are: syncope, severe blood hypotension and ­­­­­­­­­­­­­­­­­congestive heart failure. The treatment, both prophylactic and therapeutical, would be related to the appropriate choice of stimulation mode, starting from individual analysis of each patient. We present a case of a patient with pacemaker syndrome, whose primary symptom was syncope on small physical activity, which made him unable to perform ordinary activities. The solution to the problem was substitution of single-chamber stimulation mode by a dual-chamber DDDR system, new surgery and placing of a ­­­electrode being necessary.
