The estimated 2 billion people in the world who lack access to basic health care may be heartened to hear about a 17-year-old girl from New Jersey who invented an inexpensive and portable electrocardiogram that transmits data via cellular networks.An electrocardiogram, also called EKG or ECG, is a routine test run at hospitals around the world that records the heart’s electrical activity. Electrical signals set the rhythm for the heartbeat. Doctors look at the readout of an EKG to determine heart health.
The problem is that the medical equipment typically used to perform the test is expensive and bulky, making it impractical for people who lack money and access to hospitals.
