A pacemaker is a small implanted device that helps regulate slow heart rhythms or pauses. Pacemakers are commonly used for sick sinus syndrome, heart block, or symptomatic bradycardia.
Heart and Vascular Specialists evaluates symptoms that may suggest the need for a pacemaker, reviews existing device information when available, and helps coordinate implantation or device follow-up with electrophysiology/device specialists as needed.
Symptoms patients may notice
- Severe fatigue, weakness, or exercise intolerance
- Dizziness, near-fainting, or fainting
- Slow pulse, pauses, or heart block on EKG
- Shortness of breath related to slow heart rate
- Concerns about an existing pacemaker or remote monitoring alert
How we evaluate this condition
- EKG and review of rhythm history
- Holter or event monitoring to document slow rhythm, pauses, or heart block
- Echocardiogram when heart structure or function needs assessment
- Device interrogation or remote monitoring review when available
Treatment and care options
- Referral coordination for pacemaker implantation when criteria are met
- Routine pacemaker checks and battery/function surveillance through appropriate device services
- Medication adjustment when drugs contribute to slow heart rate
- Ongoing rhythm and symptom monitoring
When to seek urgent care
