Answer to Question 1

Common causes of PVCs include acid-base imbalance, acute coronary syndromes, cardiomyopathy, digitalis toxicity, electrolyte imbalance (e.g., potassium, magnesium), exercise, heart failure, hypoxia, an increase in catecholamines and sympathetic tone (e.g., emotional stress, anxiety), medications (e.g., sympathomimetic drugs), normal variant, stimulants (e.g., caffeine, tobacco), valvular heart disease, and ventricular aneurysm.

Answer to Question 2

Rhythm Rapid and chaotic with no pattern or regularity.
Rate Cannot be determined because there are no discernible waves or complexes to measure.
P waves Not discernible.
PR interval Not discernible.
QRS duration Not discernible.
