Understanding PVCs, PACs, and PJCs

What is a key characteristic of a PVC on a rhythm strip?

• Narrow QRS complex

• Presence of a P-wave

• Regular rhythm

• Wide and bizarre QRS complex

Which of the following is a potential cause of PVCs?

• Dehydration

• Caffeine intake

• High calcium levels

• Low sodium levels

What symptom might a patient experience if they have frequent PVCs?

• Dizziness

• Increased appetite

• Improved vision

• Weight gain

What is a distinguishing feature of PACs compared to the underlying rhythm?

• Early P-waves that look different

• Consistent P-wave shape

• Absence of QRS complex

• Regular rhythm

Which of the following is a common cause of PACs?

• Low blood pressure

• Atrial enlargement

• Dehydration

• High sodium levels

What is a common treatment approach for frequent PACs?

• Increasing caffeine intake

• Beta blockers

• Surgical intervention

• High-sodium diet

What is a key characteristic of PJCs?

• Regular rhythm

• Presence of a compensatory pause

• Wide QRS complex

• P-wave issues similar to junctional rhythms

How do PJCs differ from junctional escape beats?

• PJCs are always symptomatic

• PJCs have a wide QRS complex

• PJCs have a pause before them

• PJCs occur randomly without a pause

What is a common cause of PJCs?

• Dehydration

• Increased automaticity of the AV junction

• High blood pressure

• Low sodium levels

What is a modifiable factor that can help reduce PJCs?

• Avoiding caffeine

• Increasing alcohol intake

• Increasing sodium intake

• Reducing water intake
