An arrhythmia is a problem with the speed or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. A heartbeat that is too fast is called tachycardia. A heartbeat that is too slow is called bradycardia. Most arrhythmias are harmless, but some can be serious or even life threatening. When the heart rate is too slow, too fast, or irregular, the heart may not be able to pump enough blood to the body. Lack of blood flow can damage the brain, heart, and other organs.
Despite being the most common heart arrhythmia disorder in the U.S., there is not much research on the causes of atrial fibrillation in minority populations.
In a proof of concept study, scientists at Johns Hopkins report they have successfully performed 3D personalized virtual simulations of the heart to accurately identify where cardiac specialists should electrically destroy cardiac tissue to stop potentially fatal irregular and rapid heartbeats in patients with scarring in the heart.
Butterflies in a patient's stomach are one thing, but palpitations in their chest can mean serious heart problems.
Bristol-Myers Squibb Company today announced that the U.S. Food and Drug Administration accepted its supplemental Biologics License Application for Sprycel (dasatinib) in combination with chemotherapy for the treatment of pediatric patients with newly diagnosed Philadelphia chromosome-positive acute lymphoblastic leukemia.
A clinical trial of more than 1,000 patients with implantable cardioverter defibrillators found that the drug ranolazine was safe but didn't significantly decrease the likelihood of the first occurrence of ventricular tachycardia, ventricular fibrillation or death in this high-risk population.
Left atrial fibrosis may explain the increased risk of arrhythmias seen in highly trained endurance athletes, according to research presented today at ESC Congress 2018.
Scientists at the Virginia Tech Carilion Research Institute have found evidence that may disrupt conventional understanding about how electrical activity travels in the heart -; a discovery that potentially can lead to new insight into medical problems such as heart arrhythmia and sudden cardiac death.
Royal Philips, a global leader in health technology, today introduced the EPIQ CVx cardiovascular ultrasound system. Built on the powerful EPIQ ultrasound platform, EPIQ CVx is specifically designed to increase diagnostic confidence and simplify workflow for clinicians, giving them more time to interact with their patients and reducing the need for repeat scans.
A toxin from the desert bush spider is helping researchers understand more about human and insect biology, which could lead to new treatments for health conditions and bee-friendly insecticides.
Merck, known as MSD outside the United States and Canada, today announced that KEYTRUDA, Merck's anti-PD-1 therapy, has been approved by the China National Drug Administration for the treatment of adult patients with unresectable or metastatic melanoma following failure of one prior line of therapy.
Merck, known as MSD outside the United States and Canada, announced today that the pivotal Phase 3 KEYNOTE-048 trial investigating KEYTRUDA, Merck's anti-PD-1 therapy, for first-line treatment of recurrent or metastatic head and neck squamous cell carcinoma, met a primary endpoint of overall survival as monotherapy in patients whose tumors expressed PD-L1.
Harvard University researchers have bioengineered a three-dimensional model of a human left heart ventricle that could be used to study diseases, test drugs and develop patient-specific treatments for heart conditions such as arrhythmia.
New evidence published today shows there is little or no effect of omega 3 supplements on our risk of experiencing heart disease, stroke or death.
The more you smoke, the greater your risk of a heart rhythm disorder called atrial fibrillation. That's the finding of a study published today in the European Journal of Preventive Cardiology, a European Society of Cardiology (ESC) journal.(1)
Toyoda Gosei Co., Ltd. and EBM Corporation have developed a prototype "Super BEAT" surgical training simulator that can reproduce the beating of the heart with extreme accuracy using e-Rubber, an artificial muscle that functions with electricity.
People with irregular heartbeat due to a condition called atrial fibrillation, are often prescribed blood thinners to reduce the risk of blood clots that can cause a stroke.
Using catheter-based ablation instead of medications alone reduces the risks of death and stroke in patients with the common form of heart arrhythmia known as atrial fibrillation, or AFib, new research from UC Davis physicians shows.
Clinical laboratories often rely on medical articles and public information on gene disease associations in determining the genes to include on genetic testing panels for specific conditions or the specific results to return to patients.
Investigators at Children's Hospital Los Angeles and the University of Southern California have demonstrated the feasibility of implanting a micropacemaker system in the pericardial sac surrounding the heart -- a breakthrough that may open up new cardiac pacing options for children and adults.
Wearable defibrillators may be a safe and effective alternative to surgically implanted devices among children with ventricular arrythmias that increase the risk of sudden cardiac death, according to a new study.
