ELECTROCARDIOGRAPH
What is Electrocardiograph?
An electrocardiogram records the electrical signals in your heart. It's a common test used to detect heart problems and monitor the heart's status in many situations.
Where is it used?
Electrocardiograms — also called ECGs or EKGs — are often done in a doctor's office, a clinic or a hospital room. And they've become standard equipment in operating rooms and ambulances.
How does it work?
Each beat of your heart is triggered by an electrical impulse normally generated from special cells in the upper right chamber of your heart (pacemaker cells). An electrocardiogram records the timing and strength of these signals as they travel through your heart.The electrical activity is recorded as waves on a graph, with different patterns corresponding to each electrical phase of your heartbeat so an abnormal heart rhythm can be seen on a graph.
