Paroxysmal Ventricular Standstill: A Rare Cardiac Manifestation of Syncope.

Am J Case Rep 2020 Jun 17;21:e924381. Epub 2020 Jun 17.

Emergency Department, Charing Cross Hospital, Imperial College Healthcare NHS Trust, London, United Kingdom.

BACKGROUND Transient abrupt loss of consciousness due to sudden but pronounced decrease in cardiac output caused by a change in heart rate and rhythm is termed Stokes-Adams disease. Causes of Stokes-Adams syndrome are 1) transition from normal rhythm to high grade block, 2) slowing of idioventricular rhythm in the course of complete heart block, and 3) abnormal ventricular rhythm such as ventricular tachycardia and ventricular fibrillation. Paroxysmal ventricular standstill is one of the rarest causes of Stokes-Adams attack. Read More

High-energy external defibrillation and transcutaneous pacing during MRI: feasibility and safety.

J Cardiovasc Magn Reson 2019 08 5;21(1):47. Epub 2019 Aug 5.

Department of Internal Medicine, The University of Iowa, Iowa City, IA, USA.

Background: Rapid application of external defibrillation, a crucial first-line therapy for ventricular fibrillation and cardiac arrest, is currently unavailable in the setting of magnetic resonance imaging (MRI), raising concerns about patient safety during MRI tests and MRI-guided procedures, particularly in patients with cardiovascular diseases. The objective of this study was to examine the feasibility and safety of defibrillation/pacing for the entire range of clinically useful shock energies inside the MRI bore and during scans, using defibrillation/pacing outside the magnet as a control.

Methods: Experiments were conducted using a commercial defibrillator (LIFEPAK 20, Physio-Control, Redmond, Washington, USA) with a custom high-voltage, twisted-pair cable with two mounted resonant floating radiofrequency traps to reduce emission from the defibrillator and the MRI scanner.

High-fidelity simulation of transcutaneous cardiac pacing: characteristics and limitations of available high-fidelity simulators, and description of an alternative two-mannequin model.

Simul Healthc 2015 Apr;10(2):122-7

From the Department of Anesthesiology (A.R., I.T., M.G.), and Centre d'apprentissage des attitudes et habiletés cliniques (R.P., J.-F.G.), Faculty of Medicine, Université de Montréal, Montreal, Quebec, Canada.

Introduction: Transcutaneous cardiac pacing (TCP) is a potentially lifesaving technique that is part of the recommended treatment for symptomatic bradycardia. Transcutaneous cardiac pacing however is used uncommonly, and its successful application is not straightforward. Simulation could, therefore, play an important role in the teaching and assessment of TCP competence. Read More

Unnecessary shock from an implantable cardioverter-defibrillator following transcutaneous pacing.

CJEM 2014 Jul;16(4):330-3

As the population ages and cardiovascular disease becomes more prevalent, an increasing number of patients are receiving implantable cardioverter-defibrillators (ICDs). When these patients present to the emergency department, it is imperative that physicians are not only aware of the possible underlying medical issues that may have precipitated their admission but should also have a good understanding of the potential interactions that any medical intervention may have on the patient's device. We discuss a case in which a patient known to have an ICD in situ was transcutaneously paced for the management of bradycardia, leading to an unnecessary shock. Read More

Sedation for electrophysiological procedures.

Pacing Clin Electrophysiol 2014 Jun 20;37(6):781-90. Epub 2014 Feb 20.

Department of Cardiology, Westmead Hospital and University of Sydney, Sydney, NSW, Australia.

Administration of intravenous sedation (IVS) has become an integral component of procedural cardiac electrophysiology. IVS is employed in diagnostic and ablation procedures for transcutaneous treatment of cardiac arrhythmias, electrical cardioversion of arrhythmias, and the insertion of implantable electronic devices including pacemakers, defibrillators, and loop recorders. Sedation is frequently performed by nursing staff under the supervision of the proceduralist and in the absence of specialist anesthesiologists. Read More

Anesthetic management of a 2-day-old with complete congenital heart block.

Saudi J Anaesth 2014 Jan;8(1):134-7

Department of Anesthesiology and Intensive Care, All India Institute of Medical Sciences, New Delhi, India.

Maternal connective tissue disorders such as Systemic Lupus Erythematosus (most common), Sjogren's syndrome, mixed connective tissue disorders may lead to the rare condition of complete congenital heart block in the neonate. Rare fetal syndromes such as myocarditis, 18p syndrome, mucopolysaccharidoses and mitochondrial diseases are other causes. The mortality rate of this condition is inversely propotional to the age of presentation being 6 % in the neonatal age group. Read More

Piezoelectric electrocardiographic artifact in a patient after surgery with bradycardia and hypotension.

Ann Noninvasive Electrocardiol 2014 Nov 6;19(6):598-600. Epub 2014 Mar 6.

Cedars-Sinai Heart Institute, Los Angeles, CA.

A 64-year-old man was evaluated by a rapid response team for altered mental status shortly after an uncomplicated surgery. He was found to be hypotensive and bradycardic, and an emergent electrocardiogram showed extra "P" wave complexes, ultimately found to be piezoelectric artifacts from a fluid infusion pump. Equipment-related artifacts have been known to mimic arrhythmias prompting unnecessary therapeutic interventions including antiarrhythmics and direct current shocks. Read More

Life-threatening QT prolongation in a boy with attention-deficit/hyperactivity disorder on atomoxetine.

Eur J Pediatr 2014 Dec;173(12):1631-4

As a noncentral nerve-stimulating agent blocking reuptake of noradrenalin, atomoxetine is used for treatment of attention-deficit/hyperactivity disorder (ADHD). Because it has less potential for addiction and abuse and improves core symptoms of ADHD, it is commonly prescribed in many children and adolescents internationally. Its common side effects include headache, abdominal pain, decreased appetite, and weight loss. Read More

Bradydysrhythmias represent a collection of cardiac conduction abnormalities that span the spectrum of emergency presentations, from relatively benign conditions to conditions that represent serious, life-threatening emergencies. This review presents the electrocardiographic findings seen in common bradydysrhythmias and emphasizes prompt recognition of these patterns. Underlying etiologies that may accompany these conduction abnormalities are discussed, including bradydysrhythmias that are reflex mediated (including trauma induced) and those with metabolic, environmental, infectious, and toxicologic causes.
