Electrocardiogram (EKG)

The EKG can be used to see how your heart is working. A computer records your heart activity.

How is the investigation carried out?
During the EKG examination, you lie on a couch. Six electrodes will be attached to your chest and four more to your hands and feet. The electrodes are connected to the EKG machine, which records how your heart is working.

 

Other names:
Electrocardiography

Information on technology:
In the wall of the right auricle, an electrical impulse is sent over the entire heart muscle to the ventricles.
These impulses are recorded in the ECG. The device amplifies the impulses so that the result can be displayed as a curve on a screen or printed out on paper.

Amazing:
The first EKG machine weighed 175 kg, at least 4 people were required to operate it. The first portable device was created in 1926. The devices are now so small that they can be tied to the patient's waist.
