Normalization of increasing shocking coil impedance with full output synchronized shock.
J Cardiovasc Electrophysiol
November 2024
Department of Cardiovascular Medicine, Hokkaido University Graduate School of Medicine, Sapporo, Japan.
Article Synopsis
- - Impedance is an important factor for cardiovascular implantable electronic devices (CIEDs), and low voltage sub-threshold measurement (LVSM) is commonly used to measure it, although it can sometimes be inaccurate due to tissue changes.
- - A case study showed that elevated LVSM shock impedance (LVSM-SI) occurred 8 years after lead implantation, likely due to tissue encapsulation around the lead, but normal values were found after administering a high voltage shock.
- - The study suggests that performing a full-output synchronized shock test can help evaluate high voltage shock impedance (HVSI) when LVSM-SI readings are abnormal, potentially restoring normal LVSM-SI values.

Arrhytmia Unit, Cardiology Department, Hospital Miguel Servet, Zaragoza, Spain.
Article Synopsis
- The study evaluates the effectiveness of low energy synchronous shock (LESS) in measuring shock impedance during subcutaneous implantable cardioverter-defibrillator (S-ICD) implantation, focusing on its potential to predict the success of defibrillation testing (DFT).
- It finds a strong correlation between LESS and DFT impedance values, indicating that LESS can accurately reflect defibrillation success, especially in patients with higher body mass index (BMI).
- The analysis concludes that LESS impedance can serve as a useful intraoperative predictor for successful DFT, achieving good diagnostic accuracy with a specific cutoff value.

J Emerg Med
September 2023
Department of Emergency Medicine, New York-Presbyterian Hospital Cornell and Columbia, New York, New York.
Article Synopsis
- Brugada syndrome (BrS) is a genetic heart condition that can cause sudden cardiac death, and certain medications, like procainamide, can trigger its symptoms, as highlighted in a case study of a young man treated for atrial fibrillation (AF).
- The patient developed a Brugada type I pattern on his ECG after receiving procainamide, but both his AF and the Brugada pattern resolved within 24 hours, allowing him to be discharged without needing a defibrillator.
- Emergency physicians should be aware that procainamide can induce the Brugada pattern in patients, and even low-risk individuals should be referred to cardiology for further assessment, as they might not be diagnosed with

July 2023
Department of Anesthesia, Debre Tabor University, Debre Tabor, Ethiopia.
Article Synopsis
- Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common type of tachycardia treated in emergency rooms, often first treated with vagal maneuvers and adenosine.
- In cases where these initial treatments fail, medications like verapamil, diltiazem, or beta-blockers are typically used, while unstable patients may require synchronized cardioversion.
- A case in Ethiopia highlighted the successful use of digoxin for a patient with unstable paroxysmal supraventricular tachycardia (PSVT) when standard treatments weren't available, suggesting it might be a viable alternative worth further study.

Review of atrial fibrillation for the general paediatrician.
J Paediatr Child Health
October 2021
Department of Cardiology, Royal Children's Hospital, Melbourne, Victoria, Australia.
Article Synopsis
- Paediatric atrial fibrillation (AF) is rare in children without congenital heart disease, as their heart structure typically can’t sustain this arrhythmia, so any case requires thorough evaluation for hidden heart issues.
- If a child is unstable due to AF, immediate synchronized cardioversion is necessary, while stable cases should be referred to a paediatric cardiologist for further discussion.
- Complications from sustained AF can include tachycardia-induced cardiomyopathy and thromboembolism, necessitating anticoagulation treatment; age and body mass index are risk factors, with obesity and athletics linked to increased likelihood of AF.
Anticoagulation in Atrial Fibrillation Cardioversion: What Is Crucial to Take into Account.
J Clin Med
July 2021
Division of Cardiology, Garibaldi-Nesima Hospital, 95123 Catania, Italy.
Article Synopsis
- The management of atrial fibrillation (AF) involves a dilemma between rhythm control (restoring normal heart rhythm) and rate control (slowing heart rate), with electrical or pharmacological cardioversion (CV) often being used.
- Recent guidelines emphasize the importance of anticoagulation based on the individual risk of blood clots, highlighting the shift from traditional Vitamin K antagonists (VKAs) to more effective non-vitamin K antagonist oral anticoagulants (NOACs).
- In emergency situations or unstable patients, immediate electrical cardioversion (ECV) is necessary, and careful plans for anticoagulation must be followed, especially in cases of AF lasting over 48 hours to reduce thromboembolic risks.
