Metabolism and arrhythmia.

Arrhythmia and metabolism

Cardiac arrhythmias represent a major cause of mortality in the Western world. Recent research has advanced our understanding of the cellular and molecular mechanisms of arrhythmogenesis and has demonstrated that some of the causes of arrhythmias may occur as a result of perturbations in cardiac energy metabolism. These alterations in cardiac energy metabolism can have direct effects on the act...

Effect of gallic acid on electrophysiological properties and ventricular arrhythmia following chemical-induced arrhythmia in rat

Objective(s): Ventricular arrhythmias including ventricular tachycardia (VT) and ventricular fibrillation (VF) are the most important causes of mortality rate. Gallic acid (GA) has beneficial effects on cardiovascular diseases. The aim of this study was to evaluate the effects of GA on electrophysiological parameters such as QRS complex, heart rate (HR), PR interval pa...

Caffeine and arrhythmia.

Many dietary supplements promise to improve physical and mental functioning, but caffeine, an age-old food component, is one of the few that delivers. Caffeine makes its consumers awake and alert, and it improves performance (1). Therefore, coffee could be called a functional food. But is it safe? If coffee were discovered today, it would probably be regarded, in the European Union’s terminolog...

Multiple and Concurrent Arrhythmia.

Given the unique interventional emphasis in our specialty, Teaching Rounds in Cardiac Electrophysiology has frequently centered on the pearls and pitfalls associated with electrogram analysis and complications of lead implant extraction or ablation and in mapping complex arrhythmia circuits. In this issue of Circulation: Arrhythmia and Electrophysiology, Fabrizio et al, in a refreshing departur...
