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.
The two "shockable" rhythms are ventricular fibrillation and pulseless ventricular tachycardia, while the two "non-shockable" rhythms are asystole and pulseless electrical activity. [65] Moreover, in the post-resuscitation patient, a 12-lead EKG can help identify some causes of cardiac arrest, such as STEMI which may require specific treatments.
The 4 main cardiac arrest rhythms are ventricular fibrillation (VF), pulseless ventricular tachycardia (pVT), asystole, and pulseless electrical activity (PEA). Ventricular tachycardia. ventricular fibrillation (VF): disorganized and rapid quivering of the ventricles; pulseless ventricular tachycardia (pVT): organized wide QRS complexes with no ...
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.
Sinoatrial arrest is a medical condition wherein the sinoatrial node of the heart transiently ceases to generate the electrical impulses that normally stimulate the myocardial tissues to contract and thus the heart to beat. It is defined as lasting from 2.0 seconds to several minutes. [1]
According to the CDC, the specific objectives of the project are: [7]. To quantify the incidence and location of cardiac arrest events; To track the performance of each component of the Emergency Medical Services system (e.g., 9-1-1 dispatching and pre-arrival phone instructions, bystander care, first responder, ALS ambulance and definitive care)
Most adults who can be saved from cardiac arrest are in ventricular fibrillation or pulseless ventricular tachycardia, which means their heart has fallen out of rhythm. [14] Early defibrillation is the link in the chain most likely to improve survival since defibrillation can help shock the heart back into a regular beat. [ 15 ]
Precordial thump is a medical procedure used in the treatment of ventricular fibrillation or pulseless ventricular tachycardia under certain conditions. The procedure has a very low success rate, but may be used in those with witnessed, monitored onset of one of the "shockable" cardiac rhythms if a defibrillator is not immediately available.
