An EKG, also called an electrocardiogram, records the electrical activity of the heart using small electrodes placed on the skin. It is quick, painless, and commonly used as an initial test for heart rhythm and heart-related symptoms.
An EKG can identify fast or slow rhythms, irregular beats, conduction problems, signs of prior heart damage, and sometimes signs of active heart strain or ischemia.
Symptoms patients may notice
- Chest pain, pressure, or discomfort
- Palpitations, skipped beats, racing heart, or irregular pulse
- Dizziness, fainting, weakness, or shortness of breath
- Slow heart rate, fast heart rate, or known rhythm disorder
- Pre-procedure or medication-related rhythm assessment
How we evaluate this condition
- In-office EKG recording when clinically appropriate
- Comparison with prior EKGs when available
- Follow-up rhythm monitoring, echo, stress testing, or emergency referral depending on findings
Treatment and care options
- Medication adjustment, rhythm monitoring, or cardiology follow-up based on results
- Emergency referral if EKG suggests acute or dangerous findings
- Pacemaker, electrophysiology, or advanced testing coordination when indicated
When to seek urgent care
Call 911 for active chest pain, severe shortness of breath, fainting, stroke symptoms, or severe weakness. An outpatient EKG should not delay emergency care.
