Abstract

A 41-year-old farmer sustained a high-voltage electrical injury resulting in confusion, electrical burns and paroxysmal atrial fibrillation which spontaneously reverted to sinus rhythm after a few hours. Two weeks later he presented with a sudden onset of headache, unsteadiness, horizontal oscillopsia and paraesthesia in the right side of his face. Examination revealed nystagmus to the right, right-sided limb ataxia and a tendency to veer toward the right when walking. An MRI of the brain demonstrated an acute infarct of the right cerebellar hemisphere in the territory of the right posterior inferior cerebellar artery. A transesophageal echocardiogram showed a ruptured mitral valve chordae. This is the first report of a cardio-embolic stroke secondary to mitral valve chordae rupture as a delayed complication of high-voltage electrical injury. Although many mechanisms of direct cerebral electrical injury have been speculated, a cardio-embolic origin should not be overlooked as a cause of stroke secondary to high-voltage electrical injury.

Acute Stroke

A stroke occurs when blood supply to the brain is interrupted depriving the brain of oxygen and nutrients. This feed focuses cerebrovascular accidents including ischemic and paralytic stroke.

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.

Atrial Filbrillation

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

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.
