Can a pacemaker induce a thoracic PNS?
Symptomatic or asymptomatic cardiac pacemaker–induced PNS produces detectable thoracic vibrations that can be distinguished from cardiac sounds. Pacemaker‐induced PNS can alter hemodynamic function regardless of whether the PNS is symptomatic or asymptomatic.
Is there a way to detect phrenic nerve stimulation?
The authors investigated acoustic cardiography, the digital analysis of electrocardiogram (ECG) and heart sounds, to detect phrenic nerve stimulation (PNS) and assess its hemodynamic significance. They studied 42 patients and induced 46 instances of PNS induced through cardiac pacing at various locations in the heart.
How does the phrenic nerve pacing device work?
The device applies repetitive stimulus patterns to the phrenic nerves, which causes smooth, rhythmic contractions of the diaphragm, resulting in the inhalation of air into the lungs. The external transmitter and antenna send energy and stimulus information to the passive receiver implant.
Which is the only diaphragm pacing system approved?
The Avery Diaphragm Pacing System System is the only diaphragm-pacing system with full pre-market approval from the USFDA and CE marking privileges under the European Active Implantable Medical Device Directive for both adult and pediatric use.
