Cardiac arrest4
- Asystole is the most serious form of cardiac arrest and is usually irreversible. (wikipedia.org)
- Asystole is found initially in only about 28% of cardiac arrest cases in hospitalized patients, but only 15% of these survive, even with the benefit of an intensive care unit, with the rate being lower (6%) for those already prescribed drugs for high blood pressure. (wikipedia.org)
- Successful transcutaneous external pacing for asystole following cardiac arrest. (bmj.com)
- The initial rhythm post cardiac arrest was pulseless electrical activity (41.7%) or asystole (35.2%) in the majority of cases. (bvsalud.org)
Pulseless2
- Recent reports consistently point to a substantial decline in the incidence of ventricular fibrillation (VF) as the initial rhythm observed by Emergency Medical Service (EMS) responders and a complementary increase in pulseless electrical activity (PEA) and asystole. (diva-portal.org)
- For VF, pulseless VT, asystole, and PEA, epinephrine is used as a rapid IV push, which may be repeated every three minutes for a maximum of three doses. (aclsonline.us)
Bradycardia4
- Episodes of asystole and bradycardia have been documented as manifestations of left temporal lobe complex partial seizures. (medscape.com)
- Conclusions: Although current research has not been able to establish a scientific base for the use of PP in extreme bradycardia and p-wave asystole, several case reports have been published. (internationaljpp.com)
- Has also been used successfully in the treatment of tricyclic antidepressant-induced anticholinergic toxicity, but currently is rarely used because of potentially serious adverse effects (seizures, bronchospasm, bradycardia, asystole). (drugs.com)
- By implementing dedicated algorithms and sensing parameters similar to those of implanted cardioverter defibrillators (ICDs) and pacemakers, the new-generation ICMs are also able to automatically detect (i.e. without any active intervention by the patient) any kind of arrhythmic event (Fig. 1): from bradycardia to asystole, and from atrial fibrillation (AF) to ventricular tachycardia. (medscape.com)
Ventricular tachycardia3
- Examples of common conditions that can result in secondary asystole include suffocation, near drowning, stroke, massive pulmonary embolus, hyperkalemia, hypothermia, myocardial infarction (MI) complicated by VF or ventricular tachycardia (VT) that deteriorates to asystole, post defibrillation, and sedative-hypnotic or narcotic overdoses leading to respiratory failure. (medscape.com)
- Asystole is a very brief pause in the heartbeat and should not be confused with other types of less severe abnormal rhythms such as ventricular tachycardia or supraventricular tachycardia (SVT). (aedusa.com)
- Ventricular tachycardia, or VT, is an abnormal rapid heartbeat, which can be life-threatening because it may lead to ventricular fibrillation, asystole , and sudden cardiac death. (tmcnet.com)
Defibrillation3
- Several interventions previously recommended-such as defibrillation (known to be ineffective on asystole, but previously performed in case the rhythm was actually very fine ventricular fibrillation) and intravenous atropine-are no longer part of the routine protocols recommended by most major international bodies. (wikipedia.org)
- Asystole or bradyasystole follows untreated ventricular fibrillation and commonly occurs after unsuccessful attempts at defibrillation. (medscape.com)
- Patients with asystole have a much lower survival rate and are not "shockable" by defibrillation. (aedusa.com)
Shockable rhythm1
- asystole is itself not a "shockable" rhythm. (wikipedia.org)
Rhythm7
- Even in the rare case that a rhythm reappears, if asystole has persisted for fifteen minutes or more, the brain will have been deprived of oxygen long enough to cause severe hypoxic brain damage, resulting in brain death or persistent vegetative state. (wikipedia.org)
- ECG lead showing asystole (flatline) Asystole Ventricular fibrillation Agonal heart rhythm Ictal asystole Harper, Douglas. (wikipedia.org)
- Rhythm strip showing asystole. (medscape.com)
- The prognosis in asystole depends on the etiology of the asystolic rhythm, the timing of interventions, and the success or failure of advanced cardiac life support. (aedusa.com)
- The prognosis in asystole, or an irregular heart rate, depends on the etiology of the rhythm and whether interventions give positive results. (aedusa.com)
- Even when a person who suffers from asystole is converted to a less severe rhythm that can be treated with CPR and cardiac drugs, discharge from the hospital is not always possible. (aedusa.com)
- to avoid throwing the rhythm into asystole. (medpreps.com)
Occur4
- Asystole should not be confused with very brief pauses below 3 seconds in the heart's electrical activity that can occur in certain less severe abnormal rhythms. (wikipedia.org)
- In an excellent discussion of asystole in electroconvulsive therapy, Dr. McCall makes a number of useful suggestions to minimize the likelihood that asystole will occur. (psychiatrist.com)
- Asystole can occur following an indirect lightning strike (ie, direct current [DC]) that depolarizes all the cardiac pacemakers. (medscape.com)
- Carefully weigh risks and potential benefits of physostigmine therapy when making individual decisions about its use since serious adverse effects (including seizures and asystole) may occur with physostigmine therapy. (drugs.com)
Cardiopulmonary2
- Asystole is treated by cardiopulmonary resuscitation (CPR) combined with an intravenous vasopressor such as epinephrine (a.k.a. adrenaline). (wikipedia.org)
- Cardiopulmonary resuscitation (CPR) using closed-chest cardiac massage technique was first used in 1960 by Kouwenhoven in 17 patients with cardiac asystole and 3 patients with ventricular fibrillation, with a successful resuscitation in 14 patients (70%) [ 1 ]. (hindawi.com)
Prognosis1
- Asystole is different from very fine occurrences of ventricular fibrillation, though both have a poor prognosis, and untreated fine VF will lead to asystole. (wikipedia.org)
Episodes2
- Brittle, erratic heartbeats may produce sudden episodes of asystole that are indistinguishable from pauses in the electrical signal generated by the heart. (aedusa.com)
- In 10 patients with ictal asystole, we observed 76 clinical seizures with 26 ictal asystole episodes, 15 of which led to syncope. (wustl.edu)
Ictal4
- Ictal Asystole and Ictal Syncope: Insights into Clinical Management. (wustl.edu)
- BACKGROUND: -Ictal asystole is a rare, serious, and often treatable cause of syncope. (wustl.edu)
- METHODS AND RESULTS: -We searched our epilepsy monitoring unit database from October 2003 through July 2013 for all patients with ictal asystole events. (wustl.edu)
- During ictal asystole events, 4 patients had left temporal seizure onset, 4 patients had right temporal seizure onset, and 2 patients had both. (wustl.edu)
Flatline2
- 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. (wikipedia.org)
- Asystole is typically referred to as a "flatline" and is a state of a cardiac standstill with no cardiac output and no ventricular depolarization. (aedusa.com)
Combined with an intravenous vasopressor1

Contraction2
- Asystole (New Latin, from Greek privative a "not, without" + systolē "contraction") 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). (wikipedia.org)
- The term 'asystole' comes from Latin, meaning the complete lack of contraction. (aedusa.com)
