Modern interest in vasopressors as a treatment for cardiac arrest stem mostly from canine studies performed in the 1960s by anesthesiologists Dr. John W. Pearson and Dr. Joseph Stafford Redding in which they demonstrated improved outcomes with the use of adjunct intracardiac epinephrine injection during resuscitation attempts after induced ...
Cardiac arrest; Other names: Sudden cardiac death (SCD), cardiopulmonary arrest, circulatory arrest, sudden cardiac arrest (SCA) [1] CPR being administered during a simulation of cardiac arrest: Specialty: Cardiology, emergency medicine: Symptoms: Decreased level or total loss of consciousness, abnormal or no breathing, no pulse [1] [2 ...
In most states, the intravenous injection is a series of drugs given in a set sequence, designed to first induce unconsciousness followed by death through paralysis of respiratory muscles and/or by cardiac arrest through depolarization of cardiac muscle cells. The execution of the condemned in most states involves three separate injections (in ...
Cardiac arrest. More than 350,000 people experience out-of-hospital sudden cardiac arrest in the U.S. each year, and only 10% survive. Bystander CPR increases this rate to 30%, and the added use ...
When heart arrest occurs outside of a hospital, the main treatment is a shock with an automatic external defibrillator. These defibrillators are commonly installed in public places like train ...

Sympathomimetic drugs are used to treat cardiac arrest and low blood pressure, or even delay premature labor, among other things. These drugs can act through several mechanisms, such as directly activating postsynaptic receptors, blocking breakdown and reuptake of certain neurotransmitters, or stimulating production and release of catecholamines.
Another emergency that can lead to cardiac arrest, commotio cordis, is a disruption of heart rhythm after a blow to the area directly over the heart at a key time during a heartbeat cycle.
