Diabetics can also benefit with CRT

...ractions of the heart's ventricles by transmitting electrical impulses, so that blood is pumped with added efficiency. It is estimated that above 200,000 patients suffering heart failure from around the world, have been fitted with a CRT device. Uta C. Hoppe, MD, Department of Medicine III, University of Colo...

First Implantable artificial heart gets FDA’s approva

...to freely move for about 2 hours. Plugging into an electrical outlet while the batteries are being recharged can charge the system. The size of the device permits it to be implanted only in people who are at least 6 feet tall and weigh at least 170 pounds, Zuckerman said. Hence, it may not be of use to most w...

Fight Back Against Inherited Sudden-Death Heart Condition

...egular tests to monitor their heart muscle and its electrical activity. Implanted devices called defibrillators — which can detect a dangerous heart-rhythm problem instantly and restore normal rhythm — can help prevent sudden death in adults and children with serious HCM-related rhythm problems. For those who...

Epilepsy Needs To Be Managed Carefully

...hat is caused by the disturbance in balance of the electrical signals being sent by brain cells to each other. People with epilepsy must be careful when driving since seizures can be triggered off on the way. // The National Epilepsy Foundation says that epilepsy can be triggered by 'conditions that affect th...

Closing in on Lethal Heart Rhythm in Young Athletes

...ion to warrant implantation of a defibrillator, an electrical device that corrects any disturbances in the heart's rhythm. The Hopkins researchers identified the DSG2 mutation through genetic analysis of blood taken from 60 men and women already diagnosed with ARVD. All were part of a patient database created...

Factors Associated With Increased Risk of Cardiac Arrest For Adolescents

Slow brain waves integral in coordination of complex activity

...mation moves between these areas." By measuring electrical activity in the brains of pre-surgical epilepsy patients, the researchers have found the first evidence that slow brain oscillations, or theta waves, "tune in" the fast brain oscillations called high-gamma waves that signal the transmission of inform...

Vitamin Shots to Combat MS Pain

Patients usually develop a form of the disease called relapsing-remitting MS, where outs of illness are followed by complete or partial recovery during which stage anti-inflammatory drugs can help. However this s...
