Is it a typical crosstalk: Need for re‐implantation?

Abstract

With constantly evolving technology and an ever-increasing number of patients with pacemakers, clinicians will encounter various pacemaker malfunctions in their practice. While some of these issues can be solved even by using only the pacemaker׳s mode settings, others require re-intervention; neglecting a pacemaker׳s malfunction without full investigation threatens the patient׳s life. In this report, we describe a patient with a dual-chamber pacemaker with neglected or unresolved dyssynchronization that occurred 2 years after implantation.

Syncope in a patient with a dual‐chamber pacemaker: What is the possible mechanism?

“…It is seen on the ECG strip as paced atrial P-waves without ventricular output. Crosstalk is rarely seen with current dual-chamber pacemakers because of the ventricular blanking period [2].In the present case, the pacing spikes were evidently synchronized with the QRS complexes, with a 150-ms interval between two spikes. This pattern only occurs when the leads are switched (Fig.…”

“…Atrial lead dislodgement to the ventricle should be briefly considered; however, since ventricular pacing in such a situation would be inhibited or within the atrioventricular safety window, this diagnosis is incorrect. The diagnosis of switched leads in a permanent pacemaker is usually made within a few hours or days after implantation, but this complication is rarely overlooked in the long-term, as in the present case [2][3][4].…”

Kaya et al. Is it a typical crosstalk: Need for re‐implantation?

“…I have read with attention the case report by Kaya et al entitled “Is it a typical crosstalk: Need for re‐implantation?” [1] The authors described atrial lead malfunction in a patient with a dual‐chamber pacemaker. The right atrial lead tip was in close proximity to the tricuspid valve, but was it located in the ventricle or atrium?…”
