Nursing Tip: What to Do When a Patient Has PVCs | Straight A Nursing

Understanding Premature Ventricular Contractions (PVCs)

• 💡 Premature Ventricular Contractions (PVCs) are a common cardiac event, and nurses should know how to assess and manage them without immediate panic.
• 🎯 The initial step is to determine the frequency of the PVCs, noting if they are infrequent, frequent, or occur in a pattern like trigeminy (every third beat) or bigeminy (every other beat).

Assessing Hemodynamic Stability

• ⚠️ Bigeminy is more concerning than trigeminy, and both are more concerning than infrequent PVCs, especially if they affect hemodynamics.
• 📊 Blood pressure should be checked and compared to the patient's baseline to see if PVCs are causing hypotension.
• ⚡ A key assessment is to determine if the PVCs are perfusing by comparing the EKG heart rate to the pulse oximeter reading or a manually palpated radial pulse.

Electrolyte Imbalances and Interventions

• 🔬 Potassium and magnesium levels are critical electrolytes that can significantly impact heart rhythm and are common causes of frequent PVCs.
• 📞 If low electrolyte levels are identified, the nurse should notify the physician to obtain orders for electrolyte replacement, which often resolves the PVC issue.

Key Nursing Actions for PVCs

• 🔍 When a patient has PVCs, nurses should assess their frequency and pattern, check for hemodynamic effects (especially blood pressure), and evaluate potassium and magnesium levels.
• ✅ Following assessment, contact the physician to establish a treatment plan and implement necessary interventions for the patient's care.
