Imagine a farmer in a remote village who suddenly develops severe chest pain. Until recently, his family would have rushed him to the nearest city hospital, hoping they reached it in time. Every passing minute would determine whether he lived or died. Today, in many parts of Haryana, his heartbeat reaches a cardiologist before he does. An ECG recorded at the nearest health centre is transmitted instantly to a specialist, treatment begins within minutes, and the precious "golden hour", the first sixty minutes after a heart attack, can become the difference between life and death.
