India, March 5 -- Researchers found a reduction in levels of protein integrin ?1D led to abnormal heart rhythms

Scientists have linked the loss of a particular protein to abnormal heart rhythms (arrhythmia), possibly leading to identifying a cause for sudden cardiac arrests.

Researchers in China and the United States compared cellular proteins from the hearts of four patients of Arrhythmogenic Right Ventricular Cardiomyopathy (AVRC) with those in healthy hearts, according to a study published in journal Circulation on March 3, 2020.
