Catecholaminergic Polymorphic Ventricular Tachycardia: The Cardiac Arrest Where Epinephrine Is Contraindicated.

Pediatr Crit Care Med 2019 Jan 11. Epub 2019 Jan 11.

Green Lane Paediatric and Congenital Cardiac Services, Starship Children's Hospital, Auckland, New Zealand.

Objectives: To raise awareness among pediatric intensive care specialists of catecholaminergic polymorphic ventricular tachycardia; an uncommon cause of polymorphic ventricular tachycardia and ventricular fibrillation arrest in children and young adults where epinephrine (adrenaline), even when given according to international protocols, can be counter-productive and life-threatening. We review three cases of cardiac arrest in children, later proven to be catecholaminergic polymorphic ventricular tachycardia related, where delay in recognition of this condition resulted in significantly longer resuscitation efforts, more interventions, and a longer time to return of spontaneous circulation.

Design: Retrospective case series. Read More

Energy-Reduced Arrhythmia Termination Using Global Photostimulation in Optogenetic Murine Hearts.

Front Physiol 2018 27;9:1651. Epub 2018 Nov 27.

RG Biomedical Physics, Max Planck Institute for Dynamics and Self-Organization, Göttingen, Germany.

Complex spatiotemporal non-linearity as observed during cardiac arrhythmia strongly correlates with vortex-like excitation wavelengths and tissue characteristics. Therefore, the control of arrhythmic patterns requires fundamental understanding of dependencies between onset and perpetuation of arrhythmia and substrate instabilities. Available treatments, such as drug application or high-energy electrical shocks, are discussed for potential side effects resulting in prognosis worsening due to the lack of specificity and spatiotemporal precision.

Current Device Therapies for Sudden Cardiac Death Prevention - the ICD, Subcutaneous ICD and Wearable ICD.

Heart Lung Circ 2019 Jan 11;28(1):65-75. Epub 2018 Oct 11.

Department of Cardiology, Prince Charles Hospital, Brisbane, Qld, Australia.

Defibrillator technology for sudden cardiac death (SCD) prevention now includes the transvenous implantable cardiac defibrillator (ICD), subcutaneous ICD (S-ICD) and wearable cardioverter defibrillator (WCD). ICD use improves survival in patients who survived previous sudden cardiac arrest (SCA) due to ventricular tachycardia (VT)/ventricular fibrillation (VF), as well as in patients who experienced haemodynamically significant VT. It is also currently indicated for primary prevention in ischaemic/non-ischaemic cardiomyopathies, certain congenital heart disease conditions and inherited channelopathies. Read More

Can heart rate variability parameters derived by a heart rate monitor differentiate between atrial fibrillation and sinus rhythm?

BMC Vet Res 2018 Oct 25;14(1):320. Epub 2018 Oct 25.

Equine Cardioteam, Department of Large Animal Internal Medicine, Faculty of Veterinary Medicine, Ghent University, Salisburylaan 133, 9820, Merelbeke, Belgium.

Background: Heart rate variability (HRV) parameters, and especially RMSSD (root mean squared successive differences in RR interval), could distinguish atrial fibrillation (AF) from sinus rhythm(SR) in horses, as was demonstrated in a previous study. If heart rate monitors (HRM) automatically calculating RMSSD could also distinguish AF from SR, they would be useful for the monitoring of AF recurrence. The objective of the study was to assess whether RMSSD values obtained from a HRM can differentiate AF from SR in horses. Read More

Defibrillator Design and Usability May Be Impeding Timely Defibrillation.

Jt Comm J Qual Patient Saf 2018 Sep 3;44(9):536-544. Epub 2018 Jul 3.

Background: Timely defibrillation is the only rhythm-specific therapy proven to increase survival to hospital discharge following cardiac arrest secondary to ventricular tachyarrhythmia. Delayed defibrillation occurs in more than 30% of this population. A study was conducted to test the hypothesis that unintuitive defibrillator design and lack of usability are barriers to timely defibrillation, as measured by time to defibrillation and the proportion of defibrillations delivered within 2 minutes.

Medical Guidelines for Airline Travel: Management of In-Flight Cardiac Arrest.

Aerosp Med Hum Perform 2018 Aug;89(8):754-759

Introduction: Although cardiac arrest during airline flights is relatively uncommon, the unusual setting, limited resources, and the variability of the skills in medical volunteers present unique challenges. Survival in patients who suffer a witnessed arrest with a shockable rhythm who are treated promptly has improved since the advent of widely available automated external defibrillators (AEDs). In general, the chances of survival from an out-of-hospital cardiac arrest (OHCA) are greater when ventricular fibrillation (VF) is seen as the initial rhythm or if there is return of spontaneous circulation (ROSC).

European Laboratory for Non-Linear Spectroscopy, Florence, 50019, Italy.

Key Points: Although optogenetics has clearly demonstrated the feasibility of cardiac manipulation, current optical stimulation strategies lack the capability to react acutely to ongoing cardiac wave dynamics. Here, we developed an all-optical platform to monitor and control electrical activity in real-time. The methodology was applied to restore normal electrical activity after atrioventricular block and to manipulate the intraventricular propagation of the electrical wavefront. Read More

High-sensitivity troponin I in persistent atrial fibrillation - relation to NT-proBNP and markers of inflammation and haemostasis.

Scand J Clin Lab Invest 2018 Sep 22;78(5):386-392. Epub 2018 Jun 22.

a Department of Medical Research , Baerum Hospital, Vestre Viken Hospital Trust , Drammen , Norway.

Purpose: As cardiac troponins emerge as prognostic markers in atrial fibrillation (AF), it is important to identify mechanisms initiating and perpetuating cardiac troponin release, including its relations to other circulating biomarkers, in AF populations. We studied associations between high-sensitivity troponin I (hs-TnI) and markers representing myocardial wall tension, inflammation and haemostasis in persistent AF.

Methods: In a double blind, placebo-controlled study, 171 patients referred for electrical cardioversion for persistent AF were randomised to receive candesartan or placebo for 3-6 weeks before and 6 months after cardioversion. Read More

Role of Surface Electrocardiograms in Patients with Cardiac Implantable Electronic Devices.

Card Electrophysiol Clin 2018 06;10(2):233-255

Heart and Vessels Department, University of Florence, Largo Brambilla, 3, Florence 50134, Italy; Cardiovascular Department, IRCCS, Multimedica, Via Milanese 300, 20099 Sesto San Giovanni, Italy.

Surface electrocardiograms, both resting 12-lead electrocardiographs and ambulatory electrocardiograph monitoring, play an essential role in establishing indications for cardiac implantable electronic devices (pacemakers, cardiac implantable defibrillators, and cardiac resynchronization therapies), and in the evaluation of patients already implanted. Current devices have prolonged memory capabilities (defined as Holter functions) and remote monitoring functions, to evaluate the electrical properties and the automatic detection of arrhythmias. Nonetheless, surface electrocardiography remains the critical tool to detect device malfunction, evaluate programming and function, verify the automatic arrhythmia analysis and the delivered electric therapy, and prevent inappropriate intervention.

Is initial rhythm in OHCA a predictor of preceding no flow time? Implications for bystander response and ECPR candidacy evaluation.

Resuscitation 2018 07 5;128:88-92. Epub 2018 May 5.

Department of Emergency Medicine, University of British Columbia, Canada; St. Paul's Hospital, Vancouver, B.C., Canada.

Objective: Shockable cardiac rhythms are associated with improved outcomes among out-of-hospital cardiac arrests (OHCA). Initial cardiac rhythm may also be predictive of a short preceding no-flow duration. We examined the relationship between no-flow duration and initial cardiac rhythm, which may demonstrate the urgency in rescuer response and assist with candidacy evaluation for extracorporeal-cardiopulmonary resuscitation (ECPR).
