Patient discussion about asystole

Q. WHAT IS CARDIAC ARREST why do people have IT?

A. cardiac arrest is when the heart stops pumping blood. stops working. it can happen in a few cases:
1) it doesn't get oxygen and there for a part of it dies and make the whole heart stopping- heart attack.
2) in electric shock it may cause the electric pulse that generate movement in the heart to stop.
3)from harsh septic shock.
4) from any shock actually :).

The magnet can be occasionally ineffective or cause asystole in pacemaker dependency, as in our case.
Inhaler syncope is a previously undescribed form of vagally induced bradycardia and asystole resulting in syncope.
We have not been able to find a prior description of a similar case of severe bradycardia and asystole caused by iatrogenic compression of the vagus nerve in the literature.
A 6 mg dose of adenosine was administered with no effect, followed by a 12 mg bolus, which led to a 5-second asystole. The asystole converted to sinus rhythm, which became a supraventricular tachycardia of 140 bpm.
Adenosine, which causes flushing, chest pain, brief asystole to provider who thinks about using it
(3) Other cardiovascular manifestations of tricyclic overdose include hypotension, infranodal atrioventricular block, ventricular tachycardia and fibrillation, asystole, and intractable myocardial depression.
Editor's Note: Nonshockable rhythms are defined as pulseless electrical activity and asystole, which are not treatable by defibrillation.
The patient was in cyanosed and asystole condition at first.
We surmise that this resulted in subtle cardiac changes that predisposed the patient to asystole when exposed to the cardiac stress induced by nonconvulsive MECT.
Although the most common arrhythmia seen in these patients is sinus tachycardia, at least 5%-10% of patients with temporal lobe seizures develop slowing of their heart rate, some to the level of bradycardia and even asystole (Koseoglu et al., 2009).
