What does "Electrocardiography" mean?
Table of Contents
Electrocardiography, often called ECG or EKG, is a method used to check the heart's activity. It records the electrical signals that make the heart beat and helps doctors see how well the heart is working.
How Does It Work?
During an ECG test, small stickers called electrodes are placed on the skin of the chest, arms, and legs. These electrodes pick up the electrical signals from the heart. The signals are then displayed as waves on a monitor or printed on paper. Doctors look at these waves to identify any irregularities in the heart's rhythm or structure.
Why is Electrocardiography Important?
This method is important because it helps detect various heart problems, such as arrhythmias (irregular heartbeats) and heart attacks. It is a quick, safe, and non-invasive way to gather crucial information about a person’s heart health.
Applications in Research
In recent studies, ECG data has been combined with other types of data to assess mental workload and cognitive load. By doing this, researchers can understand how mental stress affects heart activity, which can lead to better insights into both mental and physical health.
