Cardiac arrhythmia-an irregular heartbeat-can develop in an instant and then quickly, and sometimes fatally, spiral out of control. In the 1960s, physician L. Julian Haywood sought a way to continuously monitor the heart for any rhythm changes. He and his associates developed this prototype digital heart monitor, which they began using in the coronary care unit at what was then Los Angeles County General Hospital, in 1969. A Control Data Corp. computer ran the software. As a pioneering Black cardiologist, Haywood recognized the disparities that racial minorities face in getting access to health care, and he spent his career working to improve heart health for all.

心脏心律不齐-一种不规则的心跳-可能会立即发展，然后迅速发展，有时甚至致命，呈螺旋形失控。在1960年代，医师L.朱利安·海伍德（L. Julian Haywood）寻求一种方法来连续监测心脏的任何节律变化。他和他的同事开发了这种原型数字心脏监护仪，并于1969年在当时的洛杉矶县总医院的冠心病监护室开始使用。一台Control Data Corp.计算机运行该软件。作为一名开创性的黑人心脏病专家，海伍德认识到少数族裔在获得医疗保健方面面临的差距，因此他一生致力于改善所有人的心脏健康。
