Through the years and experimenting, namely by D. R. Hooker and Albert Hyman, knowledge of defibrillation has been expanded and the pacemaker came into existence. Heart monitors and pulse detectors were preceded by the electrograph. In 1887 a scientist by the name of August Waller created the electrograph, which tracked the minute electrical currents in the heart. During World War Two, the field of echocardiography evolved greatly due Inge Edler and Hellmuth Hertz using a sonar ultrasonography device from a submarine and listened to Hertz heart beats. In 1960 Edler invented the first echocardiograph. Heart monitors and pulse detectors were preceded by the electrograph. X-rays and radiation are used for cardiology in order to obtain a physical view of the heart and treat certain heart conditions through radiation therapy. The automatic implantable cardiac defibrillator, or pacemaker, works by sending an electric current to the patient’s heart when they are experiencing an irregular beat or have trouble pumping blood. This implant is able to detect any fibrillation in the heart through the tracking of electric currents sent by the heart with each beat. When an irregularity, or fibrillation, in the currents in detected, the defibrillator is then activated and sends the electric current. This electric current interrupt the irregular beat and helps the heart beat normally once
