A potentially life-saving microchip has been developed to forewarn patients suffering from heart problems of any deterioration in their condition.<br /><br /> Reg Youngman<br /> is one of the first to try the microchip.<br /><br /> A tiny micro sensor has been inserted into his pulmonary artery, which monitors his heart function. <br /><br /> Everyday he is scanned and his data is sent to his hospital and medical team, if there is any indication of a problem the doctors identify it and take appropriate action.<br /><br /> Mr Youngman says the technology is reassuring: “You have more faith and trust.
