Pacing threshold varies during the 24 hours in children (Fig. 2). This variability is low, not exceeding 0.2 V (0.03 ± 0.01 V), so it is unlikely to affect pacemaker programming. There were no ...

The extravascular implantable cardioverter–defibrillator (ICD) has a single lead implanted substernally to enable pause-prevention pacing, antitachycardia pacing, and defibrillation energy similar to ...

Cardiac implantable electronic devices (CIEDs) constitute a major breakthrough in the management of heart rhythm disorders. These devices largely include bradycardia pacemakers, biventricular ...

VIENNA, Austria—Patients with chronic heart failure who require cardiac resynchronization therapy (CRT) fare better when left bundle branch (LBB) pacing is used over traditional biventricular (BiV) ...

Thirty-one consecutive patients (18 boys, 61%) who underwent the implantation of a Medtronic Kappa 901 pacemaker were enrolled. Mean age was 7.5 ± 6.2 years (median 6.5, range 1 day to 24 years).
