What is Electrocardiography?
Electrocardiography is the process of producing an electrocardiogram (ECG or EKG), which is a recording of the heart's electrical activity, a graph of voltage versus time of the heart's electrical activity using electrodes placed on the skin.
What is an ECG Machine?
ECG or EKG machine, also known as an Electrocardiograph machine uses a non-invasive diagnostic test that evaluates the heart's electrical system to assess the health and functioning of the heart.
How does an ECG Machine Work?
Each beat of the heart is triggered by an electrical impulse, normally generated from special cells in the upper right chamber of the heart. The cells in the heart go through depolarization and repolarization as the heart beats. The ECG machine records these electrical signals by attaching flat electrodes to the outer surface of the skin and a graph of the electrical activity inside the heart is generated.
Types of ECG Devices
Doctors use several types of ECG machines to check for a variety of cardiac (heart) or pulmonary (lung) conditions.
The biggest difference between regular ECG machines and Wearable ECG monitors is that unlike regular ECG Machines, which use 12 leads, the wearable ECG monitor uses just one. In the simplest terms, the 12 lead is taking lots of readings about your heart and the single lead is taking just one.
