Which portion of the ECG is most valuable in diagnosing atrioventricular (AV)conduction disturbances?

A 52-year-old patient presents to the emergency department with reports of substernal chest pain.A history is taken; serum creatine kinase (CK)and lactate dehydrogenase (LDH)isoenzymes and serum lipid studies are ordered, as is a 12-lead ECG.Which of the following results is most significant in diagnosing an MI during the first 12 hours of chest pain?

A patient with a potassium level of 2.8 mEq/L is given 60 mEq over a 12-hour period, and a repeat potassium level is obtained after the bolus.The current potassium level is 2.9 mEq/L.Which of the following should now be considered?

A 68-year-old patient is admitted to the critical care unit with reports of midchest pressure radiating into the jaw and shortness of breath when walking up stairs.The patient is admitted with a diagnosis of "rule out myocardial infarction." When inspecting the patient, the nurse notes that the patient needs to sit in a high Fowler position to breathe.This may indicate
