Final Diagnosis: Asystolic cardiac arrest in profound hypothermia and poly-substance overdose. Opioid addiction and overdose is a serious problem worldwide. Fatal overdoses from opioids are responsible for numerous deaths and are increasing, especially if taken in combination with other psychoactive substances.
Two cases of young children with frequent severe breath-holding spells complicated by prolonged asystole and seizures are reported. A ventricular pacemaker was implanted in each child, and both have subsequently remained free of syncope, although they continue to exhibit breath-holding behaviour. Breath-holding spells BHS are common in early childhood, typically occurring between the ages of six months and four years.
Welcome to our asystole reference page that provides a definition and synopsis of EKG features. Links to our practice drills, quizzes, lessons and interactive guides can be found below. Asystole is a cardiac arrest rhythm with no discernible electrical activity on the EKG monitor.
In the setting of cardiac arrest not witnessed by EMS, perform CPR immediately and continuously while setting up for rhythm analysis and delivery of shocks. If shockable rhythm present, deliver shock without delay. Mechanical CPR devices can be used as the initial compression delivery mode only if there is no delay in applying the device. If a delay in applying the device occurs, begin manual compressions immediately.
Asystole is the absence of ventricular contractions note: this is in the context of a lethal heart arrhythmianot an induced asystole on a cooled patient on a heart-lung machine and general anesthesiaduring surgery necessitating stopping the heart. Asystole is the most serious form of cardiac arrest and is usually irreversible. A cardiac flatline is the state of total cessation of electrical activity from the heartwhich means no tissue contraction from the heart muscle and therefore no blood flow to the rest of the body.

Sinus pause and sinus block are slight variations of the same rhythm, both of which may lead to an asystole which is an absence of electrical activity in the heart. However, there are other causes of asystoles as well. First we discuss sinus pause, and further down the page, asystoles.
EMS gives the report that they were called out for a 69 year old female complaining of general ill feeling and dizziness. EMS reports patient was stable in route until they rolled into the ED where patient became unresponsive, pulseless, and apneic. Emergency medicine physicians must be adept at dealing with life threatening emergencies including cardiopulmonary arrest. Cardiac arrest claims overlives a year and the majority of these events occur outside the hospital.
Along with high quality CPR, emergency medicines and defibrillation are the only two interventions that are likely to restart the arrested heart. Defibrillation a powerful tool in the hands of the ACLS practitioner and it is important to know when to use defibrillation to reset the abnormal rhythm. Rhythms that are not amenable to shock include pulseless electrical activity PEA and asystole.
