He has a history of type II diabetes, chronic obstructive pulmonary disease, hypertension and myocardial infarction. Which one of the following evaluations is most appropriate for this patient?

Question 5 of 5
Second-degree heart block type I (Wenckebach) is characterized by
Correct Answer: B
Rationale: Type I second-degree block is associated with progressively lengthening PR intervals until one P wave is not conducted and becomes a dropped beat. Second-degree block is not characterized by an absence of P waves. Type II second-degree block is associated with a consistent PR interval and dropped beats. The ECG of third-degree block shows regularly occurring P waves that are independent of the ventricular rhythm.
