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 DFT is defined as the lowest delivered energy that will convert VF to a supraventricular rhythm. An increase in DFT may lead to failure of device therapy, and as a result may have severe ...

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 ...

Have you ever listened to one piece of advice that stuck with you so much it changed the way you experience and analyze your running? It’s a powerful thing. That’s what happened when I learned a ...
