When you subscribe to EHAS the first thing we do is record a detailed medical history, conduct a general physical examination and acquire a baseline ECG that will be used for future reference. We provide you with your own personal pocket size ECG recorder/ transmitter along with guidance to use it. In case of chest pain you can transmit your ECG to our monitoring center over the telephone line. The ECG is displayed on our computer screen where it is analyzed by a team of cardiologists, who will advise you what to do next.If your ECG is within normal limits you get an instant re-assurance. In case your ECG suggests changes related to cardiac problem, we will guide your accordingly over the telephone. In Delhi, we provide our mobile CCU ambulances to bring such patients who need immediate medical care for shifting to Heart Command Center.
