Insights

Electrical storm (ES) in children is rare and challenging to manage, often requiring individualized treatment. This study characterized pediatric ES, finding diverse causes and successful outcomes with implantable cardioverter-defibrillators.

Area of Science:

  • Pediatric Cardiology
  • Electrophysiology
  • Critical Care Medicine

Background:

  • Electrical storm (ES) is a significant clinical challenge, primarily documented in adults.
  • Limited data exists on the characteristics and management of ES specifically in pediatric populations.

Purpose of the Study:

  • To characterize electrical storm in children.
  • To guide management strategies for pediatric ES based on institutional experience and literature review.

Main Methods:

  • Retrospective analysis of four pediatric patients with ES (2001-2011).
  • Systematic literature review of 47 pediatric ES cases.
  • Evaluation of patient demographics, ES characteristics, management, and outcomes.

Main Results:

  • Four pediatric patients identified (median age 5.7 years); ES varied in character and management.
  • All patients survived with implantable cardioverter-defibrillators at median 5.7-year follow-up.
  • Identified etiologies included catecholaminergic polymorphic ventricular tachycardia, Long QT syndrome, and Torsades de Pointes; iatrogenic factors were noted in 3/4 patients.

Conclusions:

  • Pediatric electrical storm is a rare emergency with diverse etiologies.
  • Individualized management approaches are crucial for pediatric ES.
  • Implantable cardioverter-defibrillators appear effective in managing pediatric ES.

Electroconvulsive Therapy01:30

Electroconvulsive Therapy

Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early years,...
Electrical Power01:07

Electrical Power

Electric power is the product of current and voltage, represented in units of joules per second, or watts. For example, cars often have one or more auxiliary power outlets with which you can charge a cell phone or other electronic devices. These outlets may be rated at 20 amps and 12 volts, so that the circuit can deliver a maximum power of 240 watts. Consider a 25 Watt bulb and a 60 Watt bulb. The conversion of electrical energy produces heat and light, while the kinetic energy lost by the...

Household Wiring And Electrical Safety

Companies that supply power to most modern households use three conductors, typically called a three-wire line. While one is neutral, the other two are both at 120 V but with opposite polarity, giving a voltage of 240 V between them. With a three-wire line, high-power appliances that require 240 V, such as electric stoves and clothes dryers, are linked between the two hot lines. 120 V appliances can be connected between the neutral and either of the hot lines. The neutral side, which is always...
Insulation Coordination01:23

Insulation Coordination

Insulation coordination is the process of matching electric equipment's insulation strength with protective device characteristics to protect the equipment against expected overvoltages. This selection is based on engineering judgment and cost. Equipment can generally withstand short-duration high transient overvoltages, but repeated tests with identical waveforms can yield inconsistent results. As a result, standard impulse voltage waveforms are used for testing, defined by specific times for...
Epilepsy ll: Types01:22

Epilepsy ll: Types

Recurrent seizures, stemming from abnormal electrical activity in the brain, are the defining characteristic of epilepsy, a chronic neurological condition. Because seizure features vary greatly, epilepsy is classified using two systems: by seizure type and by epilepsy syndromes. These classifications enable clinicians to describe seizure patterns and select suitable treatment strategies.I. Classification by Seizure Type1. Focal EpilepsyFocal epilepsy begins in one hemisphere of the brain.
Electric Charges01:11

Electric Charges

From lightning during thunderstorms to electronic devices, the phenomenon of electromagnetism is all around us. The electromagnetic force is one of the four fundamental forces of nature. It has been known to humanity in various forms for thousands of years. For example, the ancient Greek philosopher Thales of Miletus recorded his experiments on static electricity using amber and fur in the sixth century BC.
The English physicist William Gilbert studied the phenomenon of static electricity in...
