Extremely hot and cold days linked to cardiovascular deaths

2022-12-12 - 2022-12

Extremely hot and cold temperatures both increased the risk of death among people with cardiovascular diseases, such as ischemic heart disease (heart problems caused by narrowed heart arteries), stroke, heart failure and arrhythmia, according to new research published today in the American Heart Association's flagship journal Circulation.

Simulations show weak electrical pulses could treat atrial and ventricular fibrillations

2022-12-13 - 2022-12

With numerical simulations, researchers have demonstrated a new way to time weak electrical pulses that can stop certain life-threatening arrhythmias. The group shows that timed pulses are successful in ending atrial and ventricular fibrillations. The study provides early evidence that one theorized approach to controlling fibrillations -- adaptive deceleration pacing -- can improve the performance of defibrillators.

Novel wearable belt with sensors accurately monitors heart failure 24/7

2022-12-12 - 2022-12

There is a critical need for non-invasive solutions to monitor heart failure progression around the clock. This novel wearable device is based on sensors embedded in a lightweight belt that monitors thoracic impedance, electrocardiogram (ECG), heart rate and motion activity detection. The device was tested in different conditions including sitting, standing, lying down and walking. Findings showed that all of sensors kept track of the changes for all of the different conditions.
