04: Exercise & lifestyle management

Regular, moderate exercise can reduce AFib episodes, lower blood pressure, improve heart function, and support weight control, while stress management, good sleep, and maintaining a healthy weight further help prevent triggers and improve overall heart health.

Exercise Benefits for AFib 

  • Reduces AFib frequency and duration 
  • Lowers blood pressure 
  • Improves heart function 
  • Reduces stress 
  • Better weight control 

But: Too intense exercise can trigger episodes 

Safe Exercise Guidelines 

Best activities: 

  • Walking (30-45 min, 5x/week) 
  • Swimming 
  • Cycling (moderate pace) 
  • Yoga 
  • Light strength training 

Avoid: 

  • Intense competitive sports 
  • Heavy weightlifting (straining) 
  • Sprinting or HIIT 
  • Pushing to exhaustion 

Golden rule: Moderate intensity where you can talk comfortably 

Exercise Precautions 

Before starting: 

  • Get doctor clearance 
  • May need exercise stress test 
  • Know your safe heart rate range 

During exercise: 

  • Monitor how you feel 
  • Stop if palpitations start 
  • Stop if dizzy, chest pain, or very short of breath 
  • Stay hydrated 

Target heart rate: Usually 60-70% of max (ask your doctor) 

Managing Triggers 

Common AFib triggers: 

  • Alcohol (biggest) 
  • Stress 
  • Lack of sleep 
  • Dehydration 
  • Large meals 
  • Caffeine (for some) 
  • Cold medications with stimulants 
  • Overexertion 

Keep a trigger diary: 

  • When episodes occur 
  • What you ate/drank 
  • Stress level 
  • Sleep quality 
  • Activities before episode 

Patterns emerge after 4-6 weeks of tracking 

Stress Reduction 

Stress triggers AFib through: 

  • Adrenaline release 
  • Increased heart rate 
  • Inflammation 

Daily stress management: 

  • Deep breathing (5 min, 2x daily) 
  • Meditation or prayer (10 min) 
  • Gentle yoga or tai chi 
  • Nature walks 
  • Journaling 
  • Limit news/social media 

Consider therapy if chronic stress or anxiety 

Sleep Optimization 

Poor sleep worsens AFib: 

  • Get 7-9 hours nightly 
  • Consistent sleep schedule 
  • Treat sleep apnea if present (major AFib trigger) 
  • Elevate head if nighttime symptoms 

Sleep apnea and AFib: 

  • 50% of AFib patients have sleep apnea 
  • Treating sleep apnea reduces AFib 
  • Get tested if: snoring, gasping at night, daytime fatigue 

Weight Management 

Every 10 lbs lost: 

  • Reduces AFib burden 
  • Lowers blood pressure 
  • Improves heart function 

Aim for BMI < 27 if overweight
