Why the study?
Is the introduction of an atrial detector electrode by mediastinoscopy safe and effective for atrial triggered cardiac pacing in patients requiring permanent pacing?
Is the introduction of an atrial detector electrode by mediastinoscopy safe and effective for atrial triggered cardiac pacing in patients requiring permanent pacing?
Introduction of an atrial detector electrode via mediastinoscopy is technically simple but associated with a notable rate of late termination due to loss of P wave sensing or arrhythmias.
No takes yet. Share an insight, caveat, or question.
High termination rates from sensing failure or arrhythmias warrant caution; leaves open long-term utility pending controlled studies.
Carlene et al. (1977) studied this question.
