Topic Overview

If you have a pacemaker or implantable cardioverter-defibrillator (ICD), here are some exercise tips to follow during your cardiac rehab program.

• Choose continuous rhythmic activities such as walking, cycling, or water exercises.
• Always warm up and cool down.
• Avoid extreme environmental conditions. If it is too hot or cold, exercise inside only.
• Always wear loose, comfortable clothes and shoes that fit properly.
• Avoid contact sports, which may dislodge the pacemaker or ICD.
• Do not hold your breath for any reason, especially when you strain.
• STOP exercising if you feel any:
  • Pressure or pain in your chest, neck, arm, jaw, or shoulder.
  • Dizziness, lightheadedness, or nausea.
  • Unusual shortness of breath.
  • Unusual tiredness.
  • Heartbeat that feels unusual for you: too fast, too slow, or skipping a beat.
  • Other symptoms that cause you concern.
  • Shock from the ICD.

If you have an ICD, be sure you and your doctor have a plan for what to do if you get a shock. Talk to your doctor if you need to make a plan. For more information, see the topic Implantable Cardioverter-Defibrillator (ICD).
