 | | The study considered only treatment of initial asystole, though a previous study (Ornato 1985) had suggested that countershock is more effective for late asystole. | | | Also, the principal role that Vassalle postulates for increased parasympathetic tone in ventricular standstill does not apply to cases of pre-existing asystole (as a reading of the article indicates, and as JAS confirmed in a phone conversation with the author). | | | Beyond that, the study (like the Martin study) considered only treatment of initial asystole (Ornato suggested a greater incidence of late occult VF). |

| | Asystole - Wikipedia, the free encyclopedia |
| | While the heart is asystolic, there is no blood flow to the brain unless CPR or internal cardiac massage (when the chest is opened and the heart is manually compressed) is performed, and then it is still a small amount. | | | In medicine, asystole is a state of no cardiac electrical activity, hence no contractions of the myocardium and no cardiac output or blood flow. | | | Asystole is one of the conditions required for a medical practitioner to certify death. |

| | With regard to technique, in-hospital teaching programs of basic and advanced life support for both adult and pediatric patients became more widespread, and were aimed at improving outcome. | | | Previous reports have recognized that the outcome from asystole is poor. | | | Conclusion : Asystole and longer resuscitation time are associated with poorer outcome, however, successful restoration of spontaneous circulation with long-term survival can be achieved after prolonged resuscitation. |

| | The principle difference in the management of these two groups of arrhythmias is the need for attempted defibrillation in those patients with VF/VT. Subsequent actions, including chest compressions, airway management and ventilation, venous access, the administration of epinephrine (adrenaline) and the identification and correction of contributing factors, are common to both groups. | | | During the treatment of asystole or PEA, if the rhythm changes to VF, the left side of the algorithm is followed. | | | This is more likely to occur in the presence of high chest impedance and with an increasing number of shocks delivered through the same gel pads. |

| | This drug is becoming extremely difficult to obtain due to the lack of raw materials. | | | There is some suggestion that EMD/PEA, with a narrow QRS complex, has a better outcome than one with wide complex. Overall, EMD/PEA has a similar outcome to asystole. | | | It is important to secure the airway as soon as possible so that 100% oxygen can be delivered, because hypoxia and acidosis are common. As for any mechanism of cardiac arrest, adrenaline should be administered as soon as possible and circulated with adequate chest compressions and ventilations. |

| | Physical: If the rhythm is truly asystole and has been present for more than several seconds, the patient will be unconscious and unresponsive. | | | Examples of common conditions that can result in secondary asystole include suffocation, near drowning, stroke, massive pulmonary embolus, hyperkalemia, hypothermia, defibrillation, and sedative-hypnotic or narcotic overdoses leading to respiratory failure. | | | Prognosis depends on the etiology of the asystolic rhythm timing of interventions and success or failure of advanced cardiac life support. |

| | Adrenaline is not a specific treatment for asystole or ventricular fibrillation, but it does increase the effectiveness of life support. | | | Adrenaline does not convert asystole to VF, nor does it `coarsen' so-called `fine' VF. | | | Aminophylline (250 mg intravenous bolus) is an adenosine antagonist and has been reported to result in spontaneous cardiac output in some patients in asystole not responding to standard therapy. |

| | It is usually the responsibility of the most experienced doctor present and should involve the whole team. | | | If there is no cardiac monitor but a defibrillator is available, it is better to treat the rhythm as VF, as this rhythm has the best prognosis. | | | The chance of surviving asystole or EMD is improved if a reversible cause can be identified which can be treated. |

| | However, the thump is effective only if used at the onset of ventricular fibrillation or pulseless ventricular tachycardia and so should be used only when the arrest is witnessed or monitored. | | | It is therefore extremely important to determine the underlying heart rhythm as soon as possible during a resuscitation attempt. | | | The exceptions to this are patients with hypothermia or who have drowned or taken drug overdoses, when a prolonged attempt may be successful. |
