a) First-degree heart block

b) Second-degree heart block, type I

c) Second-degree heart block, type II

d) Third-degree heart block

Answer: a) First-degree heart block is characterized by a prolonged PR interval, but the QRS complex remains narrow.

a) First-degree heart block

b) Second-degree heart block, type I

c) Second-degree heart block, type II

d) Third-degree heart block

Answer: b) Second-degree heart block, type I is characterized by a progressive lengthening of the PR interval until a QRS complex is dropped, and then the cycle repeats.


A patient presents with an irregular heart rhythm and varying P-P intervals on their ECG. The QRS complex is narrow, but some P waves are not followed by a QRS complex. Which type of heart block is most likely present?

a) First-degree heart block

b) Second-degree heart block, type I

c) Second-degree heart block, type II

d) Third-degree heart block

Answer: c) Second-degree heart block, type II is characterized by a fixed PR interval with occasional dropped QRS complexes.


A patient presents with a constant PR interval of 0.20 seconds on their ECG, but the QRS complex is wide. Which type of heart block is most likely present?

a) First-degree heart block

b) Second-degree heart block, type I

c) Second-degree heart block, type II

d) Third-degree heart block

Answer: This is not characteristic of any type of heart block. The patient may have another cardiac condition, such as a bundle branch block.


A patient presents with a complete dissociation between the atria and ventricles on their ECG. The atrial rate is 75 bpm, while the ventricular rate is 40 bpm. Which type of heart block is most likely present?

a) First-degree heart block

b) Second-degree heart block, type I

c) Second-degree heart block, type II

d) Third-degree heart block

Answer: d) Third-degree heart block is characterized by a complete dissociation between the atria and ventricles, resulting in two separate rates.


A patient presents with a heart rate of 60 bpm and a constant PR interval of 0.24 seconds on their ECG. Which type of heart block is most likely present?

a) First-degree heart block

b) Second-degree heart block, type I

c) Second-degree heart block, type II

d) Third-degree heart block

Answer: This is not characteristic of any type of heart block. The patient may have a normal sinus rhythm with a slightly prolonged PR interval.


A patient presents with an irregular heart rhythm and varying P-P intervals on their ECG. The QRS complex is wide, and some P waves are not followed by a QRS complex. Which type of heart block is most likely present?

a) First-degree heart block

b) Second-degree heart block, type I

c) Second-degree heart block, type II

d) Third-degree heart block

Answer: This may be a combination of second-degree heart block, type II and a bundle branch block.


A patient presents with a heart rate of 45 bpm and a constant PR interval of 0.26 seconds on their ECG. The QRS complex is narrow. Which type of heart block is most likely present?

a) First-degree heart block

b) Second-degree heart block, type I

c) Second-degree heart block, type II

d) Third-degree heart block

Answer: This may be a combination of sinus bradycardia and first-degree heart block. Sinus bradycardia is characterized by a heart rate less than 60 bpm, and first-degree heart block is characterized by a prolonged PR interval with a normal QRS complex.


A patient presents with a gradual lengthening of the PR interval on their ECG, followed by a dropped QRS complex. The cycle repeats, but the PR interval remains constant throughout. Which type of heart block is most likely present?

a) First-degree heart block

b) Second-degree heart block, type I

c) Second-degree heart block, type II

d) Third-degree heart block

Answer: b) Second-degree heart block, type I is characterized by a progressive lengthening of the PR interval until a QRS complex is dropped. The PR interval then resets to a shorter duration and begins the cycle again.


A patient presents with a complete dissociation between the atria and ventricles on their ECG. The atrial rate is 75 bpm, while the ventricular rate is 25 bpm. Which type of heart block is most likely present?

a) First-degree heart block

b) Second-degree heart block, type I

c) Second-degree heart block, type II

d) Third-degree heart block

Answer: d) Third-degree heart block is characterized by a complete dissociation between the atria and ventricles, resulting in two separate rates. In this case, the atrial rate is faster than the ventricular rate, which may be due to a ventricular escape rhythm.
