Answer to Question 1

C
Second-degree AV block type I is characterized by an irregular ventricular rhythm (i.e., irregular R to R intervals), more P waves than QRS complexes, and P waves that occur regularly (i.e., regular P to P intervals).

Answer to Question 2

The left main coronary artery supplies oxygenated blood to its two primary branches: the left anterior descending (LAD; also called the anterior interventricular) artery and the circumflex artery (CX).
