Shop for your cardiovascular products here. Find AED defibrillators, and ECG/EKG Machines. Defibrillators are also known as automated external defibrillator (AED). They restore a normal heartbeat by sending an electric pulse or shock to the heart. They can prevent or correct an arrhythmia which is a heartbeat that is uneven, too slow, or too fast. They can also restore beating if the heart suddenly stops. ECG or EKG stands for electrocardiogram. Electrocardiography is the process of recording the electrical activity of the heart using electrodes. The electrodes are placed on the skin and are used to pick up the electrical impulses of the heart. The electrodes are connected to lead cables which are then connected to the EKG machine. Find EKG paper to print results on here as well. Shop for other products like vascular dopplers and many cardiovascular accessories here at Med-Vet International.
