Technology helps heal heart arrhythmias in children
Laptop Battery By WTN News • 07/08/04 MILWAUKEE A new technology at Childrens Hospital of Wisconsin is helping to heal heart arrhythmias, or irregular beats, in children by freezing the tissue causing the abnormality.
A special catheter made by Montreal-based CryoCath Technologies reaches temperatures as low as minus 80 degrees Celsius inside the beating heart. In the catheterization laboratory at Childrens Hospital, an electrophysiologist and pediatric cardiologist guide the catheter through a vein into the patients heart. Cryotherapy then is used to numb the cells responsible for causing the problem.
Before this technology was available, we used electricity to burn the cells and not all areas of the heart were accessible, said Janette Strasburger, pediatric cardiologist at Childrens Hospital. With Cryocath, we are able to treat arrhythmias in children who otherwise might have had injury to the hearts rhythm, requiring a permanent pacemaker.
Another benefit of Cryocath is that the degree of freezing can be varied.
Cells can be cooled just enough to see if the correct location has been targeted and then ablated, added Anwer Dhala, electrophysiologist at Childrens Hospital.
Patients suffering from arrhythmias often experience a number of symptoms, including palpitations, the feeling of skipped heartbeats, dizziness, fainting, unusual fatigue, shortness of breath or chest pain or pressure.
Childrens Hospital is the only hospital in the state offering this technology to treat children.
According to the indictment, Jones would steal various IBM and Penguin computer servers from Verisign's warehouse in Virginia and sell them to Johnson. Johnson would then sell the servers to several individuals, who would sometimes place them for sale on eBay. As a result of this scheme, the indictment alleges that Jones and Johnson caused Verisign to lose more than $120, 000 worth of computer equipment. In the indictment, Jones and Johnson are charged in three counts with causing the interstate transportation of stolen property, namely IBM 330 and 335 servers, in violation of 18 U.S.C.
