Changing conduction abnormalities in a dialysis patient with fever

Cardiology in Review
Walter CoatsW H Wilson Tang

Abstract

A patient on hemodialysis with severe aortic valve disease and presumed arteriovenous fistula infection was found to have new-onset atrial fibrillation and alternating left and right bundle branch block patterns on serial electrocardiograms. These findings prompted transesophageal echocardiography, which revealed a large abscess involving the intervalvular fibrosa and the posterior cusp of the bicuspid aortic valve. Hence, basic bedside diagnostic skills remain important in the era of sophisticated imaging techniques and laboratory analyses.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

CRISPR & Staphylococcus

CRISPR-Cas system enables the editing of genes to create or correct mutations. Staphylococci are associated with life-threatening infections in hospitals, as well as the community. Here is the latest research on how CRISPR-Cas system can be used for treatment of Staphylococcal infections.

Cardiac Conduction System

The cardiac conduction system is a specialized tract of myocardial cells responsible for maintaining normal cardiac rhythm. Discover the latest research on the cardiac conduction system here.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
