  2. Asystole - Wikipedia

    en.wikipedia.org/wiki/Asystole

    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.

  3. Cardiac arrest - Wikipedia

    en.wikipedia.org/wiki/Cardiac_arrest

    Cardiac arrest (also known as sudden cardiac arrest [SCA] [11]) ... Arrhythmias such as asystole or bradycardia are more likely in children, in contrast to ...

  4. Flatline - Wikipedia

    en.wikipedia.org/wiki/Flatline

    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.

  5. Pulseless electrical activity - Wikipedia

    en.wikipedia.org/wiki/Pulseless_electrical_activity

    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.

  6. Sinoatrial arrest - Wikipedia

    en.wikipedia.org/wiki/Sinoatrial_arrest

    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]

  7. Agonal heart rhythm - Wikipedia

    en.wikipedia.org/wiki/Agonal_heart_rhythm

    In medicine, an agonal heart rhythm is a variant of asystole. Agonal heart rhythm is usually ventricular in origin. Occasional P waves and QRS complexes can be seen on the electrocardiogram. The complexes tend to be wide and bizarre in morphological appearance. [1]

  8. Cardioplegia - Wikipedia

    en.wikipedia.org/wiki/Cardioplegia

    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 ...

  9. Transcutaneous pacing - Wikipedia

    en.wikipedia.org/wiki/Transcutaneous_pacing

    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]
