Cardiac arrest (also known as sudden cardiac arrest [SCA] [11]) is when the heart suddenly and unexpectedly stops beating. [ 12 ] [ 1 ] When the heart stops beating, blood cannot properly circulate around the body and the blood flow to the brain and other organs is decreased.
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 ...
Overall, adenosine decreases the heart’s rate and force of contraction, which increases blood supply to the cardiac muscle. Given specific circumstances this mechanism (which is intended to protect the heart) may cause atropine-resistant refractory bradyasystole. [3] Adenosine's effects are concentration-dependent.
Cardiac cells have two refractory periods, the first from the beginning of phase 0 until part way through phase 3; this is known as the absolute refractory period during which it is impossible for the cell to produce another action potential. This is immediately followed, until the end of phase 3, by a relative refractory period, during which a ...
Timing the shock to the R wave prevents the delivery of the shock during the vulnerable period (or relative refractory period) of the cardiac cycle, which could induce ventricular fibrillation. If the patient is conscious, various drugs are often used to help sedate the patient and make the procedure more tolerable.
Pronger went into cardiac arrest and was unconscious for 20 seconds while he was resuscitated by members of both the Blues' and Red Wings' training staff. [7] [8] Pronger made a full recovery after an overnight stay at Henry Ford Hospital in Detroit and would be cleared to play again four days later. The incident ultimately had a negligible ...
With the advent of these strategies, cardiac arrest came to be called clinical death rather than simply death, to reflect the possibility of post-arrest resuscitation. At the onset of clinical death, consciousness is lost within several seconds, and in dogs, measurable brain activity has been measured to stop within 20 to 40 seconds. [2]
Asystole is the most serious form of cardiac arrest and is usually irreversible. Also referred to as cardiac flatline , asystole is the state of total cessation of electrical activity from the heart , which means no tissue contraction from the heart muscle and therefore no blood flow to the rest of the body.
