  2. Asystole - Wikipedia

    en.wikipedia.org/wiki/Asystole

    Asystole (New Latin, from Greek privative a "not, without" + systolē "contraction" [1] [2]) is the absence of ventricular contractions in the context of a lethal heart arrhythmia (in contrast to an induced asystole on a cooled patient on a heart-lung machine and general anesthesia during surgery necessitating stopping the heart).

  3. Cardiac arrest - Wikipedia

    en.wikipedia.org/wiki/Cardiac_arrest

    Cardiac arrest is also identified by a lack of central pulses and abnormal or absent breathing. [1] Cardiac arrest and resultant hemodynamic collapse often occur due to arrhythmias (irregular heart rhythms). Ventricular fibrillation and ventricular tachycardia are most commonly recorded. [14]

  4. 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.

  5. Return of spontaneous circulation - Wikipedia

    en.wikipedia.org/wiki/Return_of_spontaneous...

    One study showed that those who had had an out-of-hospital cardiac arrest and had achieved return of spontaneous circulation, 38% of those people had a cardiac re-arrest before arriving at the hospital with an average time of 3 minutes to re-arrest. [8] Patients with sustained ROSC generally present with post-cardiac arrest syndrome (PCAS ...

  6. 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]

  7. 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.

  8. Clinical death - Wikipedia

    en.wikipedia.org/wiki/Clinical_death

    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]

  9. Ventricular fibrillation - Wikipedia

    en.wikipedia.org/wiki/Ventricular_fibrillation

    Ventricular fibrillation is a cause of cardiac arrest. The ventricular muscle twitches randomly rather than contracting in a coordinated fashion (from the apex of the heart to the outflow of the ventricles), and so the ventricles fail to pump blood around the body – because of this, it is classified as a cardiac arrest rhythm, and patients in ...
