Effective methods to enhance medical students' cardioversion and transcutaneous cardiac pacing skills retention - a prospective controlled study.

BMC Med Educ 2022 Jun 1;22(1):417. Epub 2022 Jun 1.

Department of Internal Medicine, University Medical, Center Hamburg-Eppendorf, Hamburg, Germany.

Background: Guideline-based therapy of cardiac arrhythmias is important for many physicians from the beginning of their training. Practical training of the required skills to treat cardiac arrhythmias is useful for acquiring these skills but does not seem sufficient for skill retention. The aim of this study was to compare different retention methods for skills required to treat cardiac arrhythmias with respect to the performance of these skills in an assessment. Read More

Microvolt T-Wave Alternans Is Modulated by Acute Low-Level Tragus Stimulation in Patients With Ischemic Cardiomyopathy and Heart Failure.

Front Physiol 2021 23;12:707724. Epub 2021 Jul 23.

Cardiovascular Research Center, Massachusetts General Hospital, Boston, MA, United States.

Microvolt T-wave alternans (TWA), an oscillation in T-wave morphology of the electrocardiogram (ECG), has been associated with increased susceptibility to ventricular tachy-arrhythmias, while vagus nerve stimulation has shown promising anti-arrhythmic effects in and animal studies. We aimed to examine the effect of non-invasive, acute low-level tragus stimulation (LLTS) on TWA in patients with ischemic cardiomyopathy and heart failure. 26 patients with ischemic cardiomyopathy (left ventricular ejection fraction <35%) and chronic stable heart failure, previously implanted with an automatic implantable cardioverter defibrillator (ICD) device with an atrial lead (dual chamber ICD or cardiac resynchronization therapy defibrillator), were enrolled in the study.

Impact of Postshock Transcutaneous Pacing on Chest Compression Quality during Resuscitation: A Simulation-Based Pilot Study.

Emerg Med Int 2021 22;2021:5584632. Epub 2021 Apr 22.

Department of Medical Rescue, Poznan University of Medical Sciences, 7 Rokietnicka Street, Poznan 60-608, Poland.

Background: Successful defibrillation is commonly followed by a transient nonperfusing state. To provide perfusion in this stagnant phase, chest compressions are recommended irrespective of arrhythmia termination. Implantable cardioverters-defibrillators (ICD) used immediately after delivery of the shock are capable of pacing the heart, and this feature is commonly activated in these devices. Read More

Transcutaneous Pacing: An Emergency Nurse's Guide.

J Emerg Nurs 2021 Mar;47(2):326-330

Transcutaneous pacing is commonly performed in emergency departments to treat patients with cardiac dysrhythmias. Although emergency nurses are required to complete a standardized course that reviews components of transcutaneous pacing, such as Advanced Cardiac Life Support, performing transcutaneous pacing on patients may be done infrequently in some facilities and can lead to anxiety and fear for bedside emergency nurses, especially novice emergency nurses and nurses who infrequently care for patients requiring external pacing. This manuscript provides a practical guide for emergency nurses to care for patients who require transcutaneous pacing. Read More

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

Exposure and Confidence With Critical Nonairway Procedures: A Global Survey of Pediatric Emergency Medicine Physicians.

Pediatr Emerg Care 2021 Sep;37(9):e551-e559

School of Clinical Sciences at Monash Health, Monash University Melbourne, Australia.

Background: Children rarely experience critical illness, resulting in low exposure of emergency physicians (EPs) to critical procedures. Our primary objective was to describe senior EP confidence, most recent performance, and/or supervision of critical nonairway procedures. Secondary objectives were to compare responses between those who work exclusively in PEM and those who do not and to determine whether confidence changed for selected procedures according to increasing patient age.

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.
