Sudden Cardiac Arrest with Shockable Rhythm in Patients with Heart Failure.

Heart Rhythm 2020 Jun 3. Epub 2020 Jun 3.

Center for Cardiac Arrest Prevention, Smidt Heart Institute, Cedars-Sinai Health System, Los Angeles, CA. Electronic address:

Background: Patients with shockable sudden cardiac arrest (SCA, ventricular fibrillation/tachycardia), have significantly better resuscitation outcomes than those with non-shockable rhythms (pulseless electrical activity/asystole). Heart failure (HF) increases risk of SCA, but presenting rhythms have not been previously evaluated.

Objective: We hypothesized that based on unique characteristics, HFpEF (preserved ejection fraction, LVEF ≥50%), bHFpEF (borderline, LVEF >40% and <50%) and HFrEF (reduced EF, LVEF ≤40%), manifest significant differences in presenting rhythm during SCA. Read More

Championing survival: connecting the unknown network of responders to address out-of-hospital cardiac arrest.

Scand J Trauma Resusc Emerg Med 2020 Jun 3;28(1):49. Epub 2020 Jun 3.

Department of Neurosurgery, Imperial College London, London, UK.

Early intervention for out-of-hospital cardiac arrest (OHCA) presents a challenge for Emergency Medical Services (EMS) across Europe. Strategies designed to address this include education and training initiatives for citizens and building CPR skills capacity and awareness amongst health care professionals. However, there is a need to improve access to volunteer first responders who can commence CPR and defibrillate before the arrival of EMS. Read More

A proposed guideline for vagus nerve stimulator handling in palliative care and after death.

Epilepsia 2020 May 28. Epub 2020 May 28.

Division of Neurology, Department of Pediatrics, Montreal Children's Hospital, McGill University Health Centre, Montreal, QC, Canada.

Vagus nerve stimulation (VNS) is often used for patients with drug-resistant epilepsy. Although this intervention may improve seizure control and mood, a number of factors must be considered when patients with VNS near end of life. We reviewed relevant literature to create a proposed guideline for management of patients with VNS in palliative care and after death. Read More

Approaches to Minimizing Periprocedural Complications During Subcutaneous Implantable Cardioverter-defibrillator Placement.

J Innov Card Rhythm Manag 2020 May 15;11(5):4100-4105. Epub 2020 May 15.

Division of Cardiovascular Medicine, Wexner Medical Center, Ohio State University Medical Center, Columbus, OH, USA.

The subcutaneous implantable cardioverter-defibrillator (S-ICD) is the latest option among devices clinically available for the prevention of sudden cardiac death, with experience from previous trials and postmarketing studies supporting the feasibility and safety of this kind of system. The extracardiac positioning of the S-ICD obviates the need for transvenous leads, which translates into lower incidence rates of lead-related complications and systemic infections. This review will highlight the results of pertinent studies related to the perioperative management of S-ICDs and review potential approaches to minimizing the risk of complications such as hematoma at the pulse generator location, unsuccessful defibrillation due to suboptimal S-ICD lead and generator positioning, and postoperative pain.
