Cardiac Arrest Part II

There are 3 causes to the above condition:

Ventricular fibrillation (most common)
Treatment is to defibrillate the heart è stop the uncoordinated “quivering” of the ventricles and allow heart to reset its normal rhythm as it pumps again

Asystole
Treatment is to trigger any contraction of the heart for example CPR. Adrenaline or atropine can also be administered.

Dissociation
atrial dissociation
independent beating of the left and right atria, each with normal rhythm or with one or both having an abnormal rhythm.
atrioventricular dissociation
control of the atria by one pacemaker and of the ventricles by another, independent pacemaker.
electromechanical dissociation
continued electrical rhythmicity of the heart in the absence of effective mechanical function.
