Bifascicular Block Complicating Blunt Cardiac Injury

Abstract

A thirty-five-year-old horse trainer presented to the emergency room of the authors' hospital with minimal nonpenetrating chest injury after having been kicked by a horse. No rib or sternum fractures were demonstrated. The admission ECG demonstrated a right bundle branch block and a left anterior hemiblock that were previously absent. The authors are aware of only two similar reports, but analogous conduction disturbances might have been classified as intraventricular conduction defects. The rarity of these defects may be explained by the anatomic pathways of the bundle of His and its bifurcations.

Evaluation of the Incidence and Clinical Significance of Myocardial Contusion Following Traumatic Sternal Fracture: Retrospective Analysis of 202 Cases

“…Cardiac contusion may be immediately lethal if a severe arhythmia is induced or if severe trauma to the atrioventricular node occurs [20]. Less serious conduction disturbances such as bifascicular block are usually transient and well tolerated [9,18]. As expected, the clinical presentation of cardiac contusion varies according to the degree of trauma; however, most patients have no cardiac symptoms.…”

Tricuspid and Mitral Valve Regurgitation with Bi-fascicular Block Following a Horse Kick

“…Right bundle branch block is observed most frequently because the tricuspid valve and right heart muscle are directly damaged by blunt chest trauma ( 12 ). Arrhythmias and conduction defects are usually transient with the recovery of cardiac damage ( 13 ), but some cases require permanent implantation of a pacemaker device ( 14 ).…”

Slow progressing cardiac complications—a case report

“…1,2 Many of these injuries go unsuspected and in many cases result in no long-term disability. 3 However, some do progress to manifest themselves with arrhythmias, heart rupture, septal rupture, and other types of cardiac problems. Despite the large number of cases that are now being documented in the literature, there is no standardization and much disagreement on how to diagnosis and treat the cardiac injury.…”
