Sex: Women are more vulnerable to electric shock than men. [31] Other issues affecting lethality are frequency, which is an issue in causing cardiac arrest or muscular spasms. Very high frequency electric current causes tissue burning, but do not stimulate the nerves strongly enough to cause cardiac arrest (see electrosurgery). Also important ...
Fish & Geddes state: "Contact with 20 mA of low-frequency electrical current through the chest can be fatal". [14] The threshold electrical current RMS magnitude required to trigger cardiac arrest is well studied. [15] [16] The mechanism of cardiac arrest is typically ventricular fibrillation as opposed to ventricular asystole.
Involuntary contraction of muscles due to electrical interference which can cause bone fractures and dislocations. Interference with the electrical conductivity of organs such as the heart and nerves. This can lead to seizures, lung injury due to severe central nervous system damage, and cardiac arrest.
The main cause of cardiac arrest is two types of arrhythmias called ventricular fibrillation or ventricular tachycardia. Other potential causes include: Heart tissue scarring from a previous heart ...
For example, getting your first period at age 10 or earlier increases your risk of cardiac events. Pregnancy complications such as preeclampsia and gestational diabetes can also be warning signs ...
The underlying causes of sudden cardiac arrest can result from cardiac and non-cardiac etiologies. The most common underlying causes are different, depending on the patient's age. Common cardiac causes include coronary artery disease, non-atherosclerotic coronary artery abnormalities, structural heart damage, and inherited arrhythmias. Common ...
The most critical injuries are cardiac arrest and respiratory failure. This will often require prompt emergency care. [ 7 ] It is safe to provide care immediately, as the affected person will not retain an electrical charge after the lightning has struck, contrary to popular belief .
Cardiac arrest can also occur after a hard blow to the chest at a precise moment in the cardiac cycle, which is known as commotio cordis. Other traumatic events such as high speed car crashes can cause sufficient structural damage to induce arrest.
