Zang’s patented touchscreen Cardio Pad is Africa’s first medical tablet, which will allow health-care workers in rural areas to send the results of cardiac tests to heart specialists via a mobile-phone connection. The incidence of heart disease is rising in many low- and middle-income countries around the world due to wealthier lifestyles and greater longevity. Cameroon is no exception. According to Cameroon’s Society of Cardiologists, some 30 per cent of the country’s 22 million people suffer from high blood pressure, which is one of the key contributing factors to heart disease. Yet there are fewer than 50 heart specialists, most of whom are based in the cities of Douala and Yaoundé, leaving rural areas with virtually no cardiac care. His company, Himore Medical, sells the Cardio Pad as part of a complete diagnostic kit for about US$2,000, less than half the price of other, less portable, systems. The other components in the kit are a set of four wireless electrodes and a sensor that attaches to the patient and transmits its signals via Bluetooth to the Cardio Pad. The kit takes a digitized electrocardiogram (ECG) reading of the patient’s heart function. The health-care worker who takes this reading then transmits this information to a national data centre. Once the ECG is received, a cardiologist makes a diagnosis and sends it back to the centre to be relayed to the health-care worker treating the patient, along with prescription instructions. The Cardio Pad has the potential to become a complete telemedicine tool, allowing measurement and transmission of integrated information on a patient’s health profile, which could help diagnose many other diseases.
