What can mimic a seizure?
-Vasovagal syncope is a partial or complete interruption of awareness and may be accompanied by clonic jerks. It is associated with postural change, neck movement (baroreceptor), micturition, coughing
-Non-epileptic attack disorder, i.e. pseudoseizure, is more common in females with previous psychiatric illnesses. Often provoked by stress, incontinence is uncommon
-Cardiac arrhythmia should be especially considered in patients with cardiac history (Fig 1). May be present with myoclonus
-Hyperventilation/panic attacks with symptoms such as dizziness, vertigo, paraesthesia and altered conscious level
-Cerebral vascular event caused by temporary disturbance of blood supply to an area of the brain, which results in a sudden, brief decrease in brain function
Common reversible causes of cardiac arrest
4Hs and 4Ts
H- hypoxia
H- hypovolaemia
H- hypothermia
H- hypo/hyperkalaemia
T- thrombosis
T- tension pneumothorax
T- tamponade
T- toxins
Shockable vs non-shockable rhythms
Shockable: Ventricular fibrillation, Ventricular tachycardia
Non-shockable: Asystole, pulseless electrical activity, atrial fibrilation, atrial tachycardia
ALS for shockable rhythmns
For ventricular tachycardia or ventricular fibrillation
1 shock min 150 J (if witnessed on cardiac monitor 3 stackable shocks)
2 mins CPR
After third and fifth shock 300mg amiodarone
1mg Adrenaline every 3-5 mins
ALS non-shockable rhythmns
PEA, Atrial fibrillation, Atrial tachycardia or asystole
1mg adrenaline ASAP
Repeat 1mg adrenaline every 3-5 mins
