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

Ventricular Fibrillation Waveform Analysis During Chest Compressions to Predict Survival From Cardiac Arrest.

Circ Arrhythm Electrophysiol 2019 Jan;12(1):e006924

Center for Progress in Resuscitation (J.C., J.B., L.S., T.D.R., P.J.K., H.K.), University of Washington, Seattle.

Background: Quantitative measures of the ventricular fibrillation (VF) ECG waveform can assess myocardial physiology and predict cardiac arrest outcomes, making these measures a candidate to help guide resuscitation. Chest compressions are typically paused for waveform measure calculation because compressions cause ECG artifact. However, such pauses contradict resuscitation guideline recommendations to minimize cardiopulmonary resuscitation interruptions. Read More

Coronary sinus as a site for stable temporary atrial pacing to tide over premature ventricular complex-triggered recurrent ventricular fibrillation in a patient with severe left ventricular dysfunction after coronary bypass surgery.

Indian Heart J 2018 Dec 21;70 Suppl 3:S483-S485. Epub 2018 Aug 21.

Cardiologist, Holy Family Hospital & Research Center, Mumbai, India. Electronic address:

Use of atrial pacing has been known, yet underutilized tool for effective temporary pacing whenever needed early after cardiac surgery. The reasons may be frequent failures of epicardial wires (fixed over atria intra-operative) leading to loss of capture. Endocardial atrial pacing sites for temporary pacing are unstable and hence continuous pacing with acceptable thresholds is impossible. Read More

Out-of-hospital sudden cardiac arrest (OHCA) is a major public health issue, with a survival rate at hospital discharge that remains below 10% in most cities, despite huge investments in this domain. Early basic life support (BLS) and early defibrillation using automated external defibrillators (AEDs) stand as key elements for improving OHCA survival rate. Nevertheless, the use of AEDs in OHCA remains low, for a variety of reasons, including the number, accessibility and ease of locating AEDs, as well as bystanders' awareness of BLS manœuvres and of the need to use AEDs.

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.

Catheter Ablation of Post-Infarct VT: Mechanisms, Strategies and Outcomes.

Heart Lung Circ 2019 Jan 15;28(1):76-83. Epub 2018 Oct 15.

Centre for Heart Rhythm Disorders, University of Adelaide and the Royal Adelaide Hospital, Adelaide, SA, Australia.

Ventricular arrhythmias are one of the leading causes of death in patients with a prior myocardial infarction. Implantable cardioverter-defibrillators (ICDs) are very effective in the prevention of sudden cardiac death but the risk of recurrence remains an issue since defibrillation does not alter the underlying substrate. Recurrent ICD shocks are distressing and are associated with an increase in mortality. Read More

Single Ventilation during Cardiopulmonary Resuscitation Results in Better Neurological Outcomes in a Porcine Model of Cardiac Arrest.

Yonsei Med J 2018 Dec;59(10):1232-1239

Department of Emergency Medicine, Yonsei University Wonju College of Medicine, Wonju, Korea.

Purpose: Recent basic life support (BLS) guidelines recommend a 30:2 compression-to-ventilation ratio (CV2) or chest compression-only cardiopulmonary resuscitation (CC); however, there are inevitable risks of interruption of high-quality cardiopulmonary resuscitation (CPR) in CV2 and hypoxemia in CC. In this study, we compared the short-term outcomes among CC, CV2, and 30:1 CV ratio (CV1).

Materials And Methods: In total, 42 pigs were randomly assigned to CC, CV1, or CV2 groups. Read More
