Detecting anomalies in heart rythm

...er patients require treatment with drugs to combat arrhythmia or may be implant a defibrillator, a device similar to a pacemaker, which operates only when the heartbeat starts to get out of step. Mathematicians at the new Fraunhofer Institute ITWM together with a private service company, developed a new metho...

Skipped heartbeats should not be ignored

...inic offer some advice on arrhythmias. A sustained arrhythmia does not arise in a healthy person - unless they have had an electric shock or use illicit drugs. Heart disease and heart deformities, on the other hand, can lead to sustained arrhythmia, and these can even be fatal. They may lead to shortness of bre...

Atrial fibrillation predicts for acute ischaemic stroke

...cute ischaemic stroke One of the commonest cardiac arrhythmia is atrial//fibrillation. The risk of thromoembolic complicationsfollowing atrial fibrillation is nearly seven timesmore than those with normal sinus rhythm. Previously,studies have shown that AF is present in 15–21% ofpatients affected by stroke. The...

Blood test developed for malignant hyperthermia

...condition. The symptoms often include tachycardia, arrhythmia and rising body temperature where muscles of the skeletal system get affected. Previously it was impossible for physicians to know if the patients can be susceptible to the condition of malignant hyperthermia. So instead of prevention, importance we...

People with abnormal heart rhythms must avoid fish oil

...can actually be harmful to patients suffering from arrhythmia and abnormal heart beats, especially those patients with implanted defibrillators. Researchers have noted that, in patients who received fish oil supplements as preventive treatment, the risk of ventricular tachycardia and ventricular fibrillation w...

MRI can predict risk of cardiac arrhythmia by identification of scar tissue

...at restores the normal cardiac rhythm following an arrhythmia by delivering an electric shock. It is usually prescribed in patients with a poor ejection fraction and/or with those resistant to the electrical impulses designed for simulation of arrhythmia. The study is the first to analyze the architecture of th...

Combination therapy for patients treated with Implantable Cardioverter Defibrillator

... found to reduce the painful shocks in ventricular arrhythmia patients undergoing Implantable Cardioverter defibrillator (ICD). ICD treatment produces high voltage shocks which are used to treat fatal cases of ventricular arrhythmias, but these shocks are very painful which can be reduced by amiodarone drugs. ...

New Test Identifies Candidates For Cardiac Defibrillator

...current will be delivered through the device if an arrhythmia were to occur in a patient. The study was conducted on 549 patients over a period of two years. As the ICD implantations cost as much as $50,000, the MTWA test will contribute towards scaling down healthcare expenses. The test is estimated at only $4...

Fish Oil Can Protect Against Air Pollution Effects

...tribute to the observed therapeutic effect against arrhythmia and sudden cardiac death as a result of exposure to air pollution. The GISSI study has revealed that highly purified ethyl ester form of fish oil could reduce heart attack deaths by 45%. Previous studies have already established the health benefits...

Abnormal Heart Rhythm Controlled By Cholesterol Drugs

... days study. There was only 1 sudden death from arrhythmia among the patients who were receiving Statins, compared with 18 patients who were not on Statins and they require a shock to correct an abnormal heartbeat when compared to statin takers. Statins' benefits are may be due to their cholesterol-lowering ...

Gene That Causes Atrial Fibrillation Identified

...brillation. Atrial fibrillation is the most common arrhythmia -- or irregular heartbeat -- worldwide. In the United States alone, more than 2 million Americans suffer from atrial fibrillation, constituting a major public health epidemic. During a person's lifetime, there is a 25 percent risk this rhythm diso...

Risk of Brain Hemorrhage Rises with Old Age

.... Atrial fibrillation is the most common cardiac arrhythmia and a major risk factor for stroke. Prior studies have shown that anticoagulation medication , such as warfarin, substantially reduces the risk of atrial fibrillation-related stroke, but also increases the risk for hemorrhage. "Our findings show th...

Painkillers Linked to Still More Problems

The reason as to why the drug would cause kidney damage is still unclear.In September 2004 Merck & Co Inc. withdrew Vioxx from the market after a three-year study revealed that it doubled the risk of heart attack and strokes in patients taki...

Performing Surgery on a Beating Heart may Be Safer

Pulse Pressure Identified as Important Risk Factor for Atrial Fibrillation

...trial fibrillation (AF) is the most common chronic arrhythmia in adults and is associated with increased risk for death and stroke. An estimated 2.3 million adults in the United States have AF, and that number is expected to increase substantially as the population ages, making identification of modifiable risk...

Irregular Heartbeat Linked to Genetic Mutation

...s uncovered its role as a safeguard against atrial arrhythmia under stress conditions. The fail-safe mechanism present in most people to provide electrical stability to the heart under stress was defective in this patient. The sequencing of KATP channel genes, using genomic DNA extracted from the patient's peri...

Fruit Flies May Pave Way to New Treatments for Age-related Heart Disease

...nd sudden death. In both flies and humans, cardiac arrhythmia and dysfunctions become more common with age. The team found that mutations in the fly’s single KCNQ gene led to severe arrhythmias that would be immediately fatal to a human, but not in this insect that does not rely on the heart for oxygen supply...

Slowing the Racing Heart

...investigator of the study. Current treatment of arrhythmia requires destruction of tissue surrounding a chaotic pacemaker, followed by insertion of a mechanical pacemaker that can regulate the heartbeat. "Understanding the molecular regulation of the heart's pacemaker opens the possibility of less drastic...
