Cardiovascular manifestations of COVID-19 include cardiac rhythm disturbances, whose mechanisms, incidence, and most common types are not well established in this population. Intense inflammatory response metabolic activity contribute to recurrence pre-existing arrhythmias, other arrhythmias can occur due myocardial injury, acute coronary insufficiency, electrolyte disturbances. Brady- tachyarr...

This review highlights the applied science intrinsic to the interpretation of the electrocardiogram and cardiac arrhythmias in children.

Cardiac arrhythmias are a signi®cant cause of morbidity and mortality in the perioperative period. While literature on antiarrhythmic agent use in postoperative and non-surgical intensive care settings is expanding, randomized clinical trials examining the use of these agents in the perioperative period are scarce. Nonetheless, as our understanding of the relevant molecular targets for manipula...

Clinically, application of electric currents to the heart has been limited to defibrillation in the operating room when the heart is exposed. In this paper technics are described for the external application of stimulating and countershock currents. They have been used successfully in man to terminate ventricular standstill from any cause and to stop ventricular tachycardia or fibrillation. For...

Stress can exert adverse effect on cardiovascular health. Psychosocial stress adversely affects the autonomic homeostasis. This in turn can result in metabolic abnormalities, inflammation and dysfunction of endothelium [1]. Changes in the autonomic homeostasis can be a major trigger for ventricular tachyarrhythmias [2]. Increased sympathetic nervous activity can cause increased proarrhythmic re...

Clinical trials. In the last two years, a number of landmark clinical trials have been published which further our understanding and clinical management of patients with atrial fibrillation (AF). Two of the major goals in the treatment of this condition include reducing progression or recurrence of the arrhythmia and decreasing the risk of cardiovascular events, thereby improving quality of lif...
