Targeted drug therapy prevents exercise-induced arrhythmias

... tachycardia and ICD shocks whenever he got out of bed, Knollmann said. defibrillator therapy also can be problematic for pediatric patients (CPVT is usually ... to allow us to back off the excessively high doses of beta blockers, limit defibrillator discharges in patients with ICDs, and decrease the likelihood that we'll ...

University of Pittsburgh cardiologists identify new cardiac arrest gene

... is still not understood about the condition. It is found all over the world and presently there is no cure. The best therapy to date is to implant a defibrillator into the chests of patients who are clinically found to be at high risk. In this study we found that GPD1-L, while not an ion channel itself, is ...

Study: Paramedics save more lives when they don't follow the rules

... chest compressions. "Intubating the patient and waiting for the defibrillator to do its analysis takes time ?time a cardiac arrest victim doesn't have," ... couple of decades. Survival rates are better only if an automated external defibrillator (AED) is available and is used soon after the cardiac arrest. ...

New defibrillator signals doctor of patient's irregular heartbeat or device malfunction

... first hospital in the U.S. to implant into a patient a new FDA-approved defibrillator which automatically signals the doctor via wireless satellite transmission ... a built-in microchip of Biotronik's Lumos DR-T implantable cardioverter defibrillator (ICD) sends a signal to a satellite via a small transmitter that can be ...

Are one-third of costly implanted heart devices unnecessary? New study suggests yes

... similar test results who didn't receive ICDs. "This is the first study to demonstrate that a subset of patients who meet current criteria for defibrillator placement may not benefit at all from ICDs," says Paul Chan, M.D., M.Sc., senior author and a fellow in cardiovascular medicine at the U-M Medical ...

MIT: Pulsing light silences overactive neurons

... erratically," he said. Many epilepsy patients have implanted electrodes that periodically give their brains an electric jolt, acting as a defibrillator to shut down overactive neurons. This new research opens up the possibility of an optical implant that could do the same thing, using light instead ...

Prototype just-in-time medical device enables untrained bystanders to save lives

... after training. The JITS device prototype used in the study consisted of a dummy "victim," a pressure-sensing headrest, an anesthesia mask, defibrillator pads, and a video screen and speakers that transmit audio and visual cues to tell the user what to do and give him or her feedback about actions ...

Implanted Devices Detect High-Risk Heart Failure Patients

... stimulate both sides of the heart in coordinated fashion, which optimizes the contractability of already weakened heart muscle. Second, the defibrillator "shocks" the heart back into normal rhythm whenever the heart beats irregularly. In addition to maintaining the heart, the devices also collect ...
