The natural history of electrical injury
The natural history of electrical injury, exclusive of electrical flash burns, was determined in 64 patients. These patients sustained relatively small burns (x=11%); only nine patients (14%) had burns greater than 25%. Forty-six patients suffered 114 major complications. EKG abnormalities occurred in 36%, including major cardiac arrhythmias in ten patients. One-fourth of the patients developed neurologic sequelae (CNS-8, peripheral-8). Electrical vascular injury with subsequent arterial occlusion was responsible for many of the major amputations. Nineteen patients required 32 amputations (digits-17, hand-1, foot-2, leg-3, arm-9). Early patient referral and vigorous fluid resuscitation minimized renal failure (1.5%) and mortality (3.1%). Early fasciotomy and vigorous debridement appeared to decrease wound sepsis (8%), but apparently had little if any effect on major limb salvage. The unsolved problems of electrical injury, namely neurological and vascular sequelae, are major contributors to the high morbidity of electrical injury.

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