An electrical injury, (electric injury) or electrical shock (electric shock) is damage sustained to the skin or internal organs on direct contact with an electric current. [ 2 ] [ 3 ] The injury depends on the density of the current , tissue resistance and duration of contact. [ 4 ]
Obstructive shock is one of the four types of shock, caused by a physical obstruction in the flow of blood. [1] Obstruction can occur at the level of the great vessels or the heart itself. [2] Causes include pulmonary embolism, cardiac tamponade, and tension pneumothorax. [3] These are all life-threatening.
A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops in one of the coronary arteries of the heart, causing infarction (tissue death) to the heart muscle. [1] The most common symptom is retrosternal chest pain or discomfort that classically radiates to the left shoulder, arm, or jaw. [1]
Electrocution. Electrocution is death or severe injury caused by electric shock from electric current passing through the body. The word is derived from "electro" and "execution", but it is also used for accidental death. [1][2] The term "electrocution" was coined in 1889 in the US just before the first use of the electric chair and originally ...
Takotsubo cardiomyopathy or takotsubo syndrome (TTS), also known as stress cardiomyopathy, is a type of non- ischemic cardiomyopathy in which there is a sudden temporary weakening of the muscular portion of the heart. [4] It usually appears after a significant stressor, either physical or emotional; when caused by the latter, the condition is ...
Atrial fibrillation (AF, AFib or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of the heart. [11][12] It often begins as short periods of abnormal beating, which become longer or continuous over time. [4] It may also start as other forms of arrhythmia such as atrial flutter ...
Cardiogenic shock. Cardiogenic shock is a medical emergency resulting from inadequate blood flow to the body's organs due to the dysfunction of the heart. Signs of inadequate blood flow include low urine production (<30 mL/hour), cool arms and legs, and decreased level of consciousness. People may also have a severely low blood pressure and ...
An implantable cardioverter-defibrillator (ICD) is a battery-powered device that monitors electrical activity in the heart, and when an arrhythmia is detected, can deliver an electrical shock to terminate the abnormal rhythm. ICDs are used to prevent sudden cardiac death (SCD) in those who have survived a prior episode of sudden cardiac arrest ...
