Now findings published in the January 19th 2014 edition of the journal Nature Medicine report the discovery of a physiological process that causes the calcium-triggered arrhythmias. The researchers at the Libin Cardiovascular Institute of Alberta in Canada hope their work will one day help design molecularly tailored medications that correct the pathophysiology.

What You Must Know About Glaucoma
By Sondra Forsyth

“Is something wrong?” I asked.
