Different Types of EKG Tests: Which One Do You Need?

📚 Quick Study Guide

• 🫀 Electrocardiogram (EKG or ECG): A non-invasive test that records the electrical activity of your heart.
• 🗓️ Resting EKG: Recorded while you are lying down, at rest. Detects abnormalities present at rest.
• 🏃 Stress EKG (Exercise EKG): Recorded while you exercise (usually on a treadmill or stationary bike). Helps detect problems that occur during physical activity.
• ⏳ Holter Monitor: A small, wearable device that continuously records your heart's electrical activity for 24-48 hours (or longer). Useful for detecting infrequent or intermittent arrhythmias.
• 🔄 Event Monitor: Similar to a Holter monitor, but you only record when you experience symptoms. Can be worn for weeks or even months.
• 📍 Signal-Averaged EKG: Used to identify late potentials, which can indicate an increased risk of ventricular tachycardia.
