Analysis finds cardiac devices recalled for safety reasons infrequently subjected to premarket or postmarket testing

A cross-sectional study of cardiovascular devices found that most recalled devices did not undergo clinical testing before authorization and were not required to undergo postmarket surveillance studies. The study highlights the need for more rigorous testing and monitoring of these devices to ensure patient safety.

Understanding the role of IKACh in cardiac function

A study reveals that the acetylcholine-activated inward-rectifying potassium current (IKACh) plays a critical role in regulating cardiac pacemaker activity and heart rate. The research found that mice lacking IKACh displayed a moderate increase in resting heart rate and delayed recovery after stress or exercise.
