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.
Cardiac arrest is diagnosed by the inability to find a pulse in an unresponsive patient. [4] [1] The goal of treatment for cardiac arrest is to rapidly achieve return of spontaneous circulation using a variety of interventions including CPR, defibrillation, and/or cardiac pacing.
Following a cardiac flatline a fast intervention is a priority and can affect individual outcomes and recovery. Treatment [14] for cardiac flatline or asystole can involve: CPR (cardiopulmonary resuscitation) Administering a vasopressin such as epinephrine; Trying to identify what could be causing the cardiac flatline in the first place.

Unlike cardiac arrest, a heart attack is a circulation problem. When circulation is blocked or cut off in some way and blood is no longer supplied to the heart muscle, this can damage that muscle ...
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 ...
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 ...
Cooling treatment alone has permitted recovery after 17 minutes of clinical death at normal temperature, but with brain injury. [17] Under laboratory conditions at normal body temperature, the longest period of clinical death of a cat (after complete circulatory arrest) survived with eventual return of brain function is one hour. [18] [19]
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]
