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 ...
Traumatic cardiac arrest is a complex form of cardiac arrest often derailing from advanced cardiac life support in the sense that the emergency team must first establish the cause of the traumatic arrest and reverse these effects, for example hypovolemia and haemorrhagic shock due to a penetrating injury.
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 classic symptoms include a slow heart rate due to loss of cardiac sympathetic tone and warm skin due to dilation of the peripheral blood vessels. [20] This term can be confused with spinal shock which is a recoverable loss of function of the spinal cord after injury and does not refer to the hemodynamic instability.)
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.
Aug. 4—High-profile cases of young athletes seemingly at the pinnacle of health collapsing on the court or field after sudden cardiac arrest underscores a hazard in high school, college and pro ...
The main reason for the acute phase of ischemia-reperfusion injury is oxygen deprivation and, therefore, arrest of generation of ATP (cellular energy currency) by mitochondria oxidative phosphorylation. Tissue damage due to the general energy deficit during ischemia is followed by reperfusion (increase of oxygen level) when the injury is enhanced.
Hemopericardium can be diagnosed using echocardiography, a cardiac ultrasound. [6] Chest X-rays are also often taken when hemopericardium is suspected and would reveal an enlarged heart . [ 6 ] Other observable signs include rapid heart rate , jugular venous distension , low blood pressure , and pulsus paradoxus .
