Understanding Second Degree Type 2 Heart Blocks

What is a key difference between second degree type 1 and type 2 heart blocks?

• Type 1 has a progressively lengthening PR interval.

• Type 1 has a constant PR interval.

• Type 2 has a progressively lengthening PR interval.

• Type 2 has a variable PR interval.

What is the typical atrial rate in second degree type 2 heart blocks?

• More than 100 beats per minute

• 60 to 100 beats per minute

• Less than 60 beats per minute

• Irregular rate

Which of the following is NOT a cause of second degree type 2 heart blocks?

• Medications like beta blockers

• High blood pressure

• Advanced coronary artery disease

• Myocardial infarction

Why is second degree type 2 heart block considered more severe than type 1?

• It causes a faster ventricular rate.

• It has a variable PR interval.

• It leads to a slower ventricular rate, affecting cardiac output.

• It has a higher atrial rate.

What is a potential treatment for symptomatic second degree type 2 heart block?

• Increased fluid intake

• Temporary pacing

• Increased physical activity

• Dietary changes
