Sanborn Cardiette Portable ECG Machine

This battery-powered ECG machine registers the electrical activity of the heart. Its widespread availability gave clinicians a powerful tool for diagnosing cardiac heart disease. It was used by several generations of local physicians.

The ECG machine, like the x-ray machine, and instruments for electrocautery, was a successful technology that evolved from earlier machines used for detecting electrical currents within the body.
