Cardiac arrest, also known as sudden cardiac arrest, is when the heart suddenly and unexpectedly stops beating. [ 11 ][ 1 ] As a result, blood cannot properly circulate around the body and there is diminished blood flow to the brain and other organs. When the brain does not receive enough blood, this can cause a person to lose consciousness.
Amiodarone is an antiarrhythmic medication used to treat and prevent a number of types of cardiac dysrhythmias. [ 4 ] This includes ventricular tachycardia, ventricular fibrillation, and wide complex tachycardia, atrial fibrillation, and paroxysmal supraventricular tachycardia. [ 4 ] Evidence in cardiac arrest, however, is poor. [ 5 ]
A 2012 study published in the American Heart Association's journal Circulation found that Tasers can cause "ventricular arrhythmias, sudden cardiac arrest and even death." At least 49 people died in 2018 in the US after being shocked by police with a Taser. [3] [4] [5]
Research has made clear how linked mental and cardiac health really are. A new study suggests women might experience the association differently post-cardiac arrest.
Advanced cardiac life support, advanced cardiovascular life support (ACLS) refers to a set of clinical guidelines established by the American Heart Association (AHA) for the urgent and emergent treatment of life-threatening cardiovascular conditions that will cause or have caused cardiac arrest, using advanced medical procedures, medications, and techniques.
Pulseless electrical activity. Pulseless electrical activity (PEA) is a form of cardiac arrest in which the electrocardiogram shows a heart rhythm that should produce a pulse, but does not. Pulseless electrical activity is found initially in about 20% of out-of-hospital cardiac arrests [1] and about 50% of in-hospital cardiac arrests. [2]
Post-cardiac arrest syndrome (PCAS) is an inflammatory state of pathophysiology that can occur after a patient is resuscitated from a cardiac arrest. [1] While in a state of cardiac arrest, the body experiences a unique state of global ischemia. This ischemia results in the accumulation of metabolic waste which instigate the production of ...
The duration of problems can vary from hours to months. Complications may include heart failure due to dilated cardiomyopathy or cardiac arrest. [1] Myocarditis is most often due to a viral infection. [1] Other causes include bacterial infections, certain medications, toxins and autoimmune disorders.
