Abstract
The article presented in this issue of HeartRhythm by Maytin and Epstein 1 Maytin M. Epstein L.M. Lead electrical parameters may not predict integrity of the Sprint Fidelis ICD lead. Heart Rhythm. 2012; 9: 1446-1451 Abstract Full Text Full Text PDF PubMed Scopus (11) Google Scholar highlights an issue that is critical to the decision-making process when deciding whether to continue to reuse a lead at the time of generator change or “upgrade.” Specifically, how is it possible to know what lies beneath the surface of an apparently normally functioning lead? Patients who are followed regularly in a device clinic have the pacing and sensing thresholds as well as the pacing and (if it is an implantable defibrillator lead) high-voltage impedance of the lead measured on a regular basis. Many modern devices take daily measurements of these same parameters and provide them on device interrogation in the clinic or by remote monitoring. There are even audible and vibratory alarms that can alert the patient when lead impedance exceeds the high or low limit that has been set into the device. Pharmacotherapy in Medicare beneficiaries with atrial fibrillationHeart RhythmVol. 9Issue 9PreviewThere are limited data regarding national patterns of pharmacotherapy for atrial fibrillation (AF) among older patients. Drug exposure data are now captured for Medicare beneficiaries enrolled in prescription drug plans. Full-Text PDF
