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.

Meta AnalysisLandiolol hydrochloride for prevention of atrial fibrillation after cardiac surgery: a meta-analysis.
Atrial fibrillation (AF) is the most common arrhythmic complication after cardiac surgery. Several studies have compared the efficacy of landiolol and placebo or other agents in preventing new-onset AF in patients after cardiac surgery. In this study, we conducted a meta-analysis to determine whether landiolol is effective in preventing new-onset AF after cardiac surgery. ⋯ Landiolol administration in the perioperative period can reduce the occurrence of AF after cardiac surgery without increasing the risk of major complications. It can be used to prevent new-onset AF safely after cardiac surgery.

Comparative StudySurvival in octogenarians undergoing cardiac resynchronization therapy compared to the general population.
Many patients eligible for cardiac resynchronization therapy (CRT) are over 80 years of age. Survival in this population and how it compares to the general octogenarian population has not been established. ⋯ Octogenarians with advanced heart failure have a reasonable mean survival time following CRT. All-cause mortality in this patient population is only modestly worse compared to the general octogenarian population. Therefore, in octogenarians deemed to be reasonable candidates, CRT should not be withheld based on age alone.

Cardiac implantable electronic device reutilization: battery life of explanted devices at a tertiary care center.
Prior studies have suggested that pacemaker reuse may be a reasonable alternative to provide device therapy in the low- and middle-income countries. We studied explant indications and remaining battery life of cardiac implantable electronic devices (CIEDs) at a tertiary medical center. ⋯ The majority of explanted CIEDs for reasons other than ERI have an adequate battery life and, if proven safe, may conceivably be reutilized for basic pacing in underserved nations where access to this life-saving therapy is limited.
