Randomized Controlled Trial Multicenter StudyRandomized controlled trial of perioperative ICD management: magnet application versus reprogramming.
There are insufficient data to guide perioperative implantable cardioverter-defibrillator (ICD) management for patients undergoing surgical procedures using electrocautery. ⋯ A magnet protocol simplifies perioperative ICD management for procedures using electrocautery more than 6 inches from the ICD. This protocol results in significantly shorter time with ICD therapy off, fewer provider handoffs, no risk of inadvertently discharging patients home with ICD therapies off, and no device reset.

Acute decrease of cerebral oxygen saturation during rapid ventricular and supraventricular rhythm: a pilot study.
Monitoring of cerebral tissue oxygen saturation (SctO2 ) reflects cerebral microcirculation. We sought to characterize the decrease in SctO2 during supraventricular tachycardia (SVT) and ventricular tachycardia (VT) in adults. ⋯ Cerebral perfusion decreased during simulated SVT and VT and is influenced by age and LVEF. Clinicians can consider NIRS monitoring in patients during ablation procedures and in critical care. NIRS may especially be appropriate for the elderly and for patients with impaired LVEF.

Multicenter Study Clinical TrialImplantable defibrillators with enhanced detection algorithms: detection performance and safety results from the PainFree SST study.
Implantable defibrillators (ICD) are highly effective in reducing arrhythmia-related mortality. ICD shock therapy has been shown to increase psychological distress, health care utilization, and is associated with increased mortality. The Protecta ICDs (Medtronic Inc., Minneapolis, MN, USA) have algorithms designed to reduce unnecessary and inappropriate shock therapy. ⋯ The results of the premarket phase of the PainFree SST trial demonstrate the safety of the Protecta XT defibrillators. Detection of induced VF was not delayed with SmartShock™ algorithms ON.
