Ventricular fibrillation likely resulting from electrocautery and amiodarone: a rare clinical case report.
J Int Med Res
January 2025
Department of Anesthesiology, Shaanxi Provincial People's Hospital, Xi'an, Shaanxi, China.
Monopolar electrocautery is usually a safe and effective technique used in laparoscopic cholecystectomy and bile duct surgery, but it may lead to adverse consequences, even ventricular fibrillation (VF). Amiodarone is an effective antiarrhythmic drug commonly used in practice to treat ventricular and atrial arrhythmias, but it may induce tachyarrhythmia or even VF. We report a case of VF occurring twice during cholecystectomy.

Article Synopsis
- The study examines the effectiveness of rapid TSH screening in detecting thyroid diseases in patients in the Emergency Department (ED), noting a 7% prevalence of previously undiagnosed thyroid dysfunctions.
- The diagnostic process was enhanced by using a mobile ultrasound device, rPOCUS, to evaluate patients with suppressed rTSH in urgent care situations requiring iodinated contrast.
- Results indicate that rPOCUS is both cost- and time-effective, aiding in the management of hyperthyroidism, reducing unnecessary rTSH tests, and identifying incidental findings that necessitate further evaluation.
Unveiling the Link: Hypocalcemia-Induced Unstable Sustained Ventricular Tachycardia in Nonischemic Cardiomyopathy.
Cardiol Res
August 2024
Department of Cardiology, Texas Tech University Health Sciences Center El Paso, El Paso, TX 79905, USA.
Article Synopsis
- - A 63-year-old woman arrived at an emergency room experiencing dizziness, palpitations, and low blood pressure; she was diagnosed with ventricular tachycardia and electrolyte imbalances (low magnesium and calcium levels).
- - Despite treatment with IV amiodarone and magnesium, her tachycardia only resolved after her serum calcium levels were corrected.
- - The patient had a history of left ventricular dysfunction discovered 19 years earlier but was unaware and not on any medication; the case suggests a possible link between her underlying heart condition and the rare occurrence of hypocalcemia-related ventricular tachycardia.
Article Synopsis
- The study explores the use of a monolayer WS material as a delivery carrier for the anti-myocardial infarction drug amiodarone (AMD), finding that it maintains structural stability and has favorable adsorption energy.
- The interaction between WS and AMD involves electron transfer, with significant changes in electron density observed in specific atoms, contributing to the material's photoelectric properties.
- The research implies that WS could enhance drug delivery systems, potentially improving treatment outcomes for myocardial infarction through temperature-controlled release mechanisms and effective light absorption in relevant spectral regions.
Body surface mapping of P-waves in sinus rhythm to predict recurrence following cardioversion for atrial fibrillation.

Department of Cardiology, University Hospitals of Leicester NHS Trust, Glenfield Hospital, Leicester, United Kingdom.
Article Synopsis
- Direct current cardioversion (DCCV) is used to control rhythm in patients with persistent atrial fibrillation (AF), and the study aims to assess if P-wave parameters can predict the success of this treatment after 12 months.
- The study involved 56 males over 18, measuring P-wave characteristics using body surface mapping, and found that 44% had successful outcomes after a year, with some reverting to AF sooner.
- In patients taking amiodarone, those with higher corrected P-wave duration (PWDc) faced more recurrences; a PWDc cut-off of >161 ms was identified as a significant predictor, though general P-wave parameters did not reliably indicate the timing of AF recurrence.
