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.
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 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 ...
Arrhythmias are the main cause of cardiac arrest but can be triggered by other cardiac events such as heart attacks. Other risk factors include coronary heart disease, heart valve disease, and ...
Heart disease is a leading killer around the world and the top cause of death in the United States. It killed an estimated 17.9 million people in 2019, representing 32% of all deaths globally ...
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.
In cardiac arrest, the heart quivers with uncoordinated contractions, and the blood flow to every part of the body — including the brain — ceases. Unlike a heart attack, in which the heart ...
