This study investigated the effect of severity, distribution of CAD and left ventricular ejection fraction (LVEF) on acute ventricular pacing threshold
and lead impedance at the time of either antibradycardic pacemaker (PM) or implantable cardiac defibrillator (ICD) implantations in our institution for various indications.
was evaluated starting at an output of 5 V/.
To evaluate the dependence of the pacing threshold
current on the electrode position, a special study was performed on 15 patients.
6) only reported comparison of chronic pacing threshold
values at most recent follow-up, as it was indicated.
It allows the output to be automatically adjusted based on automatic evaluation of the pacing threshold
on April 17, provides steroid-elution, a time-released delivery of a steroid near the pacing electrode, which is intended to improve the long-term pacing threshold
It also is steroid-eluting, which may help suppress inflammation of heart tissue that could cause detrimental changes in a patient's pacing threshold
In addition, ACC is also the only such feature to automatically adjust its minimal energy output based on the patient's pacing threshold
, a physician-selected safety margin, and a clinically appropriate minimum output.
Attain Performa leads also include steroid elution on all four electrodes for lower chronic pacing thresholds
, which contribute to greater device longevity and reduce the likelihood of PNS.
The findings, which assessed device performance and patient outcomes through 12-months of follow-up, show pacing thresholds
The Model 4298 lead has a canted shape, and steroid on all four electrodes for lower pacing thresholds
IROX, a fractal coating, has been added to enhance electrical properties and lower pacing thresholds
