Abstract:
Accelerated idioventricular rhythm (AIVR) is an uncommon but benign rhythm, seen most commonly in children. It is associated with reperfusion injury after myocardial infarction in adults. In children, it is usually seen as an idiopathic finding in the absence of heart disease. We present a case of AIVR in an adolescent associated with acute presentation of inflammatory bowel disease. Prompt treatment of the systemic inflammation led to the remission of both inflammatory bowel disease and AIVR. This report emphasizes the diverse causes of AIVR in children and our limited understanding of its pathophysiology. Treatment of the underlying condition resolved the arrhythmia.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
