At Cardiac Science, we invented the first automated external defibrillator (AED) that was fully automatic, the single-channel interpretive electrocardiogram (ECG machine or EKG machine), and the first modern stress test.

We manufacture AED machines, ECG, cardiac stress and holter systems, vital signs monitors, and cardiac rehabilitation equipment. You'll find our AED and ECG / EKG machines in schools, military installations, hospitals, and doctors' offices worldwide. Cardiac Science services include AED management programs, CPR / AED training, record keeping, AED maintenance, and medical oversight of heart safe automated external defibrillator programs. We've implemented more than 20,000 AED programs worldwide.

Our cardiac care products are sold under the trusted Burdick, HeartCentrix, Powerheart, and Quinton names. At Cardiac Science, we work to improve public health by creating products for the management of heart disease.
