What device is used to pick up electrical impulses from the heart?

The device used to pick up electrical impulses from the heart is an electrode. Electrodes are conductive pads placed on the skin that detect the small electrical signals the heart generates with each heartbeat. These devices are essential for electrocardiography because they allow for the measurement and monitoring of the heart's electrical activity. The electrodes convert these electrical impulses into a readable form, which can then be displayed on an EKG monitor or printed out for analysis.

When applied to the skin, electrodes establish a connection with the body's electrical system and provide a direct path for the detection of these impulses. This capability is crucial in diagnosing various cardiac conditions, observing the heart's rhythm, and assessing overall heart health. Therefore, their role is fundamental in any electrocardiogram procedure, providing the necessary interface to capture the heart's electrical signals accurately.
