Hypothermia-related cases typically occur after exposure to low ambient temperatures; however, numerous cases occur in individuals with no history of exposure to cold environment. Hypothermia is associated with such complications as acidosis, impaired myocardial function, bleeding diathesis, and decreased kidney and liver function. The well-known electrocardiographic manifestations of hypothermia are the presence of J (Osborn) waves, prolonged PR, QRS, and QT intervals, and atrial arrhythmias. The choice of rewarming therapy is based on the degree of hypothermia. The evaluation, electrocardiographic manifestations, and management of hypothermia are reviewed.

The eye and the heart are two closely interlinked organs, and many diseases affecting the cardiovascular system manifest in the eye. To contribute to the understanding of blood flow propagation towards the retina, we developed a method to acquire electrocardiogram (ECG) coupled time-resolved dynamic optical coherence tomography (OCT) images. This method allows for continuous synchronised monitoring of the cardiac cycle and retinal blood flow dynamics.

Obesity is associated with abnormal repolarization manifested by QT interval prolongation, and oxidative stress is an important link between obesity and arrhythmias. However, the underlying electrophysiological and molecular mechanisms remain unclear. The aim of this study is to evaluate the role of obesity in potassium current in ventricular myocytes and the potential mechanism of NADPH oxidase 2 (Nox2).

A rare phenomenon involving ventricular separation: a case report.

BMC Cardiovasc Disord

Department of Electrocardiology, The Third Affiliated Hospital of Wenzhou Medical University, No.108 WansongRoad, Wenzhou, 325200, People's Republic of China.

Background: Ventricular separation is a multipart, extensive disease of the heart that hinders the electrical conduction of the cardiac system ventricular muscle, causing a bidirectional conduction block. The occurrence of ventricular separation suggests that the myocardium is in a state of severe ischemia, and the prognosis is generally poor. Herein, we present arescue case in which the extremely rare phenomenon of ventricular separation developed and was documented in realtime.

Introduction: Aluminum phosphide is a cheap and commonly used rodenticide that is also an effective solid fumigant and frequently used for grain preservation. The pill contains around 44% inert elements (ammonium carbonate) to avoid disintegration of the tablet, while the rest (about 56%) is aluminum phosphide. Because it is freely available on the market, it is one of the commonly used agents for self-poisoning in different parts of the developing world.

Article Synopsis
  • Continuous electrocardiographic (ECG) monitoring during surgery in infants and children is essential to detect potential myocardial pathologies, despite the rarity of these issues in pediatric patients.
  • A case is presented involving a 2-year-old child who showed ST segment depression and increased R wave amplitude during surgery, which led to the discovery of undiagnosed hypertrophic cardiomyopathy postoperatively.
  • The findings emphasize the importance of recognizing ECG changes and the need for thorough evaluation to prevent complications during and after surgery, even when patients appear asymptomatic.
