Terminology of Pacemaker Reentrant Tachycardias

Pacemaker‐mediated tachycardia: What is the mechanism?

“…Interestingly, such an ELT type was not included in the ELT nomenclature. 3,4 Nor was an impact of sensing assurance algorithms on the occurrence of oversensing ever reported, to the best of this author's knowledge. Apart from adding to our understanding of ELT mechanisms, this case prompts a reflection on the multitude of electrocardiographic manifestations of the lead position in an inappropriate heart chamber: from asystole and blocks to ELTs.…”

“…In consequence, a combination of ventricular oversensing, lead dislodgement, first‐degree AV block with PR interval > PVARP, PVAB, and possibly sensing assurance function created a milieu for a far‐field dual‐chamber pacemaker orthodromic ELT. Interestingly, such an ELT type was not included in the ELT nomenclature . Nor was an impact of sensing assurance algorithms on the occurrence of oversensing ever reported, to the best of this author's knowledge.…”
