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.
For management of pediatric cardiac arrest, CPR should be initiated if suspected. Guidelines provide algorithms for pediatric cardiac arrest management. Recommended medications during pediatric resuscitation include epinephrine, lidocaine, and amiodarone. [163] [81] [82] However, the use of sodium bicarbonate or calcium is not recommended.
A cardiac flatline is also called asystole. It can possibly be generated by malfunction of the electrocardiography device, but it is recommended to first rule out true asystole because of the emergence of such condition. Definition: A cardiac flatline is referred to as asystole. It can be identified by using an ECG/EKG (electrocardiogram) test.
Cardiopulmonary resuscitation (CPR) is an emergency procedure consisting of chest compressions often combined with artificial ventilation, or mouth to mouth in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest.
Transcutaneous pacing is no longer indicated for the treatment of asystole (cardiac arrest associated with a "flat line" on the ECG), with the possible exception of witnessed asystole (as in the case of bifascicular block that progresses to complete heart block without an escape rhythm). [4]
Initial symptoms may include heart asystole and respiratory arrest. [1] While the asystole may spontaneously resolve fairly rapidly, the respiratory arrest is typically more prolonged. [1] Other symptoms may include burns and blunt injuries. [1] Of those who survive, about 75% have ongoing health problems as a result, such as cataracts and ...
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 ]
High mortality rates due to cardiac injury though, made surgeons to look on how to protect the heart. In 1955 D.G. Melrose suggested ‘’elective cardiac arrest’’, a technique already used for other purposes, in order to protect the heart from ischemia- since cardiac muscle is not working, oxygen demands should be low. In the 1960’s ...
