Case in brief

A patient with a dual-chamber pacemaker and sick sinus syndrome presented with a slow, long-RP' tachycardia. Device interrogation indicated that a spontaneous PVC reset the tachycardia, ruling out atrial tachycardia. An atrial paced beat advanced the next QRS, confirming the diagnosis of AVNRT. Adjusting the AV delay successfully terminated the tachycardia episodes.

Diagnostic / clinical pearl

The case highlights the importance of pacemaker algorithms in diagnosing arrhythmias, particularly in complex cases like AVNRT.

Why it matters

Individualized programming of pacemakers can significantly impact the management of arrhythmias, enhancing patient outcomes.
