There is some evidence from observational studies to suggest that low plasma potassium levels are associated with increased risk of dangerous alterations in heart rhythms and that potassium levels in the upper normal level have protective effects.
Doctors have successfully developed an artificial intelligence-led stethoscope that can detect three heart conditions in 15 seconds. Invented in 1816, the traditional stethoscope used to listen to sounds within the body has been a vital part of every medic's toolkit for more than two centuries. Now a team have designed a hi-tech upgrade with AI capabilities that can diagnose heart failure, heart valve disease and abnormal heart rhythms almost instantly.
