What an ECG Detects
An ECG records your heart's electrical activity. It detects irregular rhythms (arrhythmia, atrial fibrillation), signs of a past or current heart attack, heart muscle thickening from high blood pressure, and electrolyte imbalances affecting heart function.
An ECG does not detect blocked arteries directly. For that, you need further testing at a hospital. But it's the first step for evaluating chest pain, palpitations, or shortness of breath.
When You Should Get an ECG
- Chest pain or pressure
- Heart palpitations or racing heartbeat
- Shortness of breath not explained by activity
- Dizziness or fainting
- History of heart disease, high blood pressure, or diabetes
- Routine screening if you're over 50
How It Works at Home
- Book a visit and mention you need an ECG.
- Lie down on a bed. Remove clothing from your chest and ankles.
- 10 electrode stickers are placed on your chest, arms, and legs. The machine records for 30 seconds. You don't feel anything.
- Results: The doctor reads the printout immediately and explains the findings. You get a copy.
What Happens if Results Are Abnormal
The doctor explains the finding and recommends next steps. This might be a cardiologist referral, additional testing, medication adjustment, or hospital transfer if urgent.
