Pacemaker Spikes and Abnermality

When evaluating a patient with a pacemaker, just think of pacer. P is for pacing spikes, are they present and appropriate? A is for awareness. Is the pacemaker appropriately sensing? C is for capture. Is every spike followed by a beat? E is for ECG. Are thereECG signs of hyperkalemia or occlusion MI? And R is for the rest of the patient, including pacemaker and mechanical complications Or do they have an emergency totally unrelated to the pacemaker, like sepsis or jablead?
