Prompt lead evaluation is advised for symptomatic patients with rising impedance; leaves open the mechanisms of late atrial lead failure.
Case Report (n=1)
This case highlights the electrocardiographic presentation of second-degree 2:1 retrograde AV block in a patient with elevated atrial lead impedance, which prevented pacemaker-induced endless-loop tachycardia.
Cunningham et al. (2017) conducted a case report in Elevated atrial lead impedance and bigeminy (n=1). New right atrial lead implantation was evaluated. An 81-year-old woman with elevated atrial lead impedance and bigeminy due to second-degree 2:1 retrograde AV block underwent uncomplicated implantation of a new right atrial lead.
