Keeping this in view, what is pea?

Pulseless electrical activity (PEA) is a clinical condition characterized by unresponsiveness and the lack of a palpable pulse in the presence of organized cardiac electrical activity.

Additionally, what causes a pea? PEA is always caused by a profound cardiovascular insult (eg, severe prolonged hypoxia or acidosis or extreme hypovolemia or flow-restricting pulmonary embolus). The initial insult weakens cardiac contraction, and this situation is exacerbated by worsening acidosis, hypoxia, and increasing vagal tone.

Additionally, why pea is not shockable?

PEA is treated much like asystole. It is not a shockable rhythm because the electrical system in the heart is actually working properly. Shocking the patient is done to 'reset' the heart's rhythm, but the problem in PEA isn't in the conduction of electrical stimuli in the heart.

How does pea look like?

PEA is one of many waveforms by ECG (including sinus rhythm) without a detectable pulse. PEA may include any pulseless waveform with the exception of VF, VT, or asystole. Hypovolemia and hypoxia are the two most common causes of PEA.
