Disclosures

Case: A 63-year-old man with a cardiac pacemaker presented with a left shoulder dislocation. His heart rate was 46 beats per minute, and pacemaker testing demonstrated an elevated pacing threshold, a decreased sensing threshold, and stable pacemaker lead impedance. Lead dislodgement due to the shoulder dislocation was suspected, and the patient underwent repositioning of the lead.

Conclusion: When a patient with a pacemaker dislocates a shoulder, it should be confirmed that the heart rate is above the programmed lower rate of the pacemaker; electrocardiography should be performed, and the pacing parameters should be checked to ensure that pacing failure is not overlooked.
