People prone to stress related heart arrhythmias may benefit from taking beta blockers.
A new Yale University study tracked nearly 200 patients who recorded their emotions just before an episode of atrial fibrillation. It showed people taking beta blockers felt anger and stress just as often as those not taking them but the impact was much smaller.
Researchers said the drugs helped block the negative effects of emotions which could improve the quality of life for the two million Americans with a heart arrhythmia.
App to help teens focus
Scientists at UC San Francisco have developed a meditation training app that could help improve memory and attention spans of young adults.
The intervention, called Medi-train, teaches users to pay attention to their breathing gradually and for longer periods of time. After just six weeks, people who used the app showed dramatic improvements, similar to those who had in-person training for several months.
