🔍 Quick A-Fib Assessment Checklist

⚡ PRIORITY: Assess hemodynamic stability first - is the patient symptomatic from the arrhythmia? 1,2
Assessment Area Key Findings 1,3,5,8 Nursing Action
Hemodynamic Status BP, HR, perfusion, chest pain Continuous monitoring, IV access
EKG Recognition Irregularly irregular, no P waves 12-lead EKG, rhythm strip
Stroke Risk CHA₂DS₂-VASc score factors Assess for contraindications to anticoagulation
Symptom Assessment Palpitations, fatigue, dyspnea Functional status evaluation
🎯 Nursing Intervention Priorities ⯆

1. Immediate Assessment (First 15 minutes)

  • Hemodynamic stability: HR, BP, perfusion, mental status
  • Symptom severity: Chest pain, dyspnea, dizziness
  • 12-lead EKG: Confirm A-Fib, assess for ischemia
  • IV access: Prepare for potential medications
Clinical Pearl: A-Fib with RVR (rapid ventricular response) >150 bpm often causes hemodynamic compromise. Be prepared for cardioversion if unstable. 1,2

2. Rate vs. Rhythm Control Strategy 1,5

Rate Control Medications

  • Beta-blockers: Metoprolol, atenolol (monitor for hypotension, bradycardia)
  • Non-dihydropyridine calcium channel blockers: Diltiazem, verapamil (avoid with heart failure with reduced ejection fraction)
  • Cardiac glycosides: Digoxin (narrow therapeutic window, monitor levels and renal function)

Nursing Consideration: Hold parameters typically HR <60 or systolic BP <90 mmHg (check facility policy). Refer to institutional protocols and drug references for specific dosing.

Rhythm Control

Agents like amiodarone may be used under cardiology guidance, especially in recent-onset A-Fib or failed rate control. Requires specialized monitoring and expertise.

3. Anticoagulation Management 1,3,5,8

  • CHA₂DS₂-VASc Assessment: CHF, Hypertension, Age ≥75 (2 points), Diabetes, Stroke/TIA (2 points), Vascular disease, Age 65-74, Sex (female) 1,3,5
  • Bleeding Risk: HAS-BLED score assessment (≥3 indicates high bleeding risk) 5
  • Medication Options: Warfarin (INR 2.0-3.0) or DOACs (apixaban, rivaroxaban, dabigatran, edoxaban) 5,8
Clinical Pearl: DOACs have fewer drug interactions than warfarin but require dose adjustments for renal function (renal dosing needed if CrCl <30 mL/min - check specific DOAC guidelines). Warfarin requires INR monitoring every 4-6 weeks when stable. 5,8
🩺 Patient Education Priorities ⯆

Medication Adherence 2,4,7,8

  • Anticoagulation: "This helps reduce the risk of stroke caused by blood clots"
  • Rate Control: "This helps your heart work more efficiently and reduces symptoms"
  • Bleeding Precautions: Soft toothbrush, electric razor, avoid contact sports, watch for unusual bruising

When to Seek Medical Attention

  • Chest pain or pressure
  • Severe shortness of breath
  • Dizziness or fainting
  • Signs of stroke (FAST assessment)
  • Unusual bleeding or bruising

Lifestyle Modifications 2,4,7

  • Limit alcohol: Can trigger A-Fib episodes
  • Manage stress: Meditation, regular exercise
  • Sleep hygiene: 7-9 hours nightly
  • Caffeine moderation: Individual tolerance varies

⚠️ Red Flags & Emergency Situations

Call Rapid Response/Code Blue for: 1,2,6
  • Systolic BP <90 mmHg with symptoms
  • Altered mental status
  • Chest pain with ST changes
  • Acute heart failure symptoms

Prepare for Cardioversion When:

  • Hemodynamically unstable A-Fib
  • Acute onset (<48 hours) with symptoms
  • Failed rate control with medications
Clinical Pearl: If the duration of A-Fib is over 48 hours or unknown, anticoagulation for 3 weeks prior to elective cardioversion is recommended unless a TEE shows no thrombus. 1,2

📋 Discharge Planning Checklist

  • ✅ Medication reconciliation completed
  • ✅ Follow-up appointments scheduled (cardiology, primary care)
  • ✅ INR monitoring arranged (if on warfarin)
  • ✅ Patient/family education documented
  • ✅ Emergency contact information provided
  • ✅ Activity restrictions reviewed
Clinical Pearl: Comprehensive discharge planning reduces readmission rates and improves patient outcomes. 1,8
