Heart arrhythmias occur when the electrical impulses that coordinate your heartbeats don’t function properly, resulting in your heart beating irregularly, too quickly or too slowly. To diagnose a heart arrhythmia, your doctor will review your symptoms and perform cardiac tests that specifically monitor arrhythmias. These tests include:
- Holter Monitor: a small, wearable device that keeps track of your heart rhythm for 24 hours while you go about your daily activities.
- Event Monitor: a portable device that you attach to your body as you experience arrhythmia symptoms.
- Zio XT Patch: a small, wearable patch that continuously records your heart rhythm for up to 14 days.
