What should I do now?

Call 911

Call 911 for fainting, chest pressure, severe trouble breathing, or severe dizziness that makes you feel you may pass out. Do not drive yourself.

Contact your care team

Contact your care team for new dizziness, unusual fatigue, near-fainting, or a drop in activity. Report device-site concerns promptly after implantation.

Keep your care plan

Keep your treatment and follow-up plan. Bring questions, readings, and your medication list.

SECTION 6

Your next visit and questions to ask

Understanding your diagnosis helps you take an active role in your care. Your cardiologist or electrophysiologist can explain what your rhythm recordings show and what happens next.

What should I bring?

  • An updated medication list, including supplements.
  • A record of symptoms: what you felt, when it happened, and what you were doing.
  • Any available watch recordings or pulse alerts.
  • Your pacemaker identification card, if you have a device.
  • Your questions—and a family member or friend, if helpful.

Questions about my diagnosis

  • Do I have sinus node dysfunction, heart block, or both?
  • If I have heart block, which type is it?
  • Does my recorded rhythm explain my symptoms?
  • Could medications or another treatable condition be contributing?
  • Is monitoring enough, or do I need treatment now?

If a pacemaker is recommended

  • Why do I need a pacemaker?
  • Which type is best for me, and why?
  • What benefits and risks should I understand?
  • What should I expect on the procedure day?
  • What restrictions will I have during recovery?

The decision considers your electrical problem, heart function, overall health, and personal goals. Your physician will explain the recommendation and answer your questions.

Before you leave, know your follow-up plan

Make sure you understand when to return, whether additional monitoring is needed, and whom to contact if symptoms change.

If you have a pacemaker, ask when your next device check is due and how to use remote monitoring.

Preparing for a device implant

The key idea: You should leave knowing your diagnosis, your treatment plan, and your next step.
