Why is Mr. L pale and clammy?

due to a sympathetic mediated response during shock, of peripheral constriction of vasculature in order to inc flow to essential organs thereby giving him a pale appearance

Why is his pulse weak and thready?

it indicates vasoconstriction and reduced filling of the vascular compartment What is the significance of his ECG findings?

T wave inversions and S-T elevation point to an MI

QT elongation predisposes to to a potentially fatal ventricular arrhythmia known as torsades de pointes which can lead to sudden cardiac death

What is CK (CPK)? What is LDH? What are they markers for? What do his blood test results indicate?

creatine phosphokinase (CPK) - increased levels can point to a possible heart attack / cardiac damage

An LDH (lactate dehydrogenase) - increased levels can point to cardiac adamage

his blood test are pointing to an increased level
