“If you start something, you must finish it,” says Arthur Zang, an inventor who started working with a mentor at the main hospital in Cameroon’s capital city, Yaoundé, seven years ago.

At the time, Zang’s mentor had to help him understand the basic science behind EKG data transmission. Today, Zang owns a company called Himore Medical, which sells a diagnostic kit that includes a touch-screen device capable of transmitting cardiac test results from rural areas to specialists via mobile phone technology.

Before manufacturing the device, Zang struggled to find financing and posted his idea for CardioPad on Facebook. He hopes to produce 500 CardioPads and distribute them to hospitals throughout the region.

In 2012, when Arthur Zang was selected to participate in the Young African Leaders Initiative mentoring program, he had already made his mark in Cameroon through his invention. But he says he has not finished what he started. He won’t be finished until he relocates production to Cameroon so his fellow citizens will benefit from the jobs it will provide.
