Collecting an ECG involves placing electrodes on a patient to record the heart's electrical activity, typically done while the patient is lying still.
An electrocardiogram (ECG or EKG) is a simple and common test used to check your heart's electrical activity. The process is generally quick and non-invasive.
The ECG Collection Process
Based on information from sources like St Vincent's Heart Health, the steps involved in collecting an ECG are straightforward:
- Preparation: You will typically lie down on a bed in a hospital or a doctor's surgery.
- Electrode Placement: Electrodes (small sticky pads) are attached to specific locations on your arms and chest. These electrodes act as sensors.
- During the Recording: You will be asked to lie still and breathe normally throughout the test. This helps ensure accurate readings free from movement artifact.
- Activity Recording: The electrodes pick up and record your heart's electrical signals as it beats.
- Display and Output: An electrocardiograph machine receives the signals from the electrodes. This device displays the heart's electrical activity on a monitor and records it on paper. The paper output is the actual electrocardiogram trace.
Summary of Steps:
- Patient lies on a bed.
- Electrodes are attached to arms and chest.
- Patient lies still and breathes normally.
- Electrodes record heart's electrical activity.
- Electrocardiograph displays and prints the activity.
This recorded pattern provides valuable information about your heart's rhythm, rate, and overall electrical health.
