The Tribune is reporting that DeRo will undergo a surgical procedure tomorrow that will hopefully cure his irregular heartbeat problems.  

Cubs physician Stephen Adams said DeRosa will have an EPS (electrophysiology study) performed on him Thursday by Dr. Alan Kadish, a cardiovascular electrophysiologist at Northwestern Memorial Hospital. The procedure involves putting a catheter in a vein in the groin which is then threaded into the heart to induce an irregular heartbeat (atrial arrthythmia).

"Depending on what they find with this diagnostic study, they will undergo what's known as a radiofrequency catheter ablation, or RFCA," Adams said. "And hopefully, depending upon what they find, it will be curative of his past problems of jumping into the (irregular heartbeat)."

The low-voltage, high-frequency electricity causes an abnormal heart rhythm and permanently burns off  small areas of tissue, preventing them from generating electrical impulses, and thus curing the individual. Adams said the procedure should take 1-2 hours, and that if all goes well, DeRosa will return to Phoenix by Sunday and could continue his baseball activities by the beginning of next week.

"By the end of (next) week, hopefully he'll be going full throttle again," Adams said.

I just hope that Lou doesn't try to push him back into the lineup too soon.

DeRo, best wishes for a very speedy recovery!
