An echocardiogram performed 3 months later demonstrated significant left ventricular dysfunction (ejection fraction 38%), and 24-hour ambulatory electrocardiograph monitoring revealed frequent ...

Engineers have developed a new wearable, ultra-thin electronic device - e-tattoo - that could make heart monitoring easier ...
