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.
An article published in International Journal of Hyperthermia proposes a more effective protocol for the treatment of cardiac arrhythmias when applying radiofrequency energy at the site of the arrhythmia by catheterization.
Earlier in the pandemic it was vital to see doctors over platforms like Zoom or FaceTime when in-person appointments posed risks of coronavirus exposure. Insurers were forced — often for the first time — to reimburse for all sorts of virtual medical visits and generally at the same price as in-person consultations.
Scientists have shed light on why some people who have a stroke do not also have abnormal heart rhythms, even though their hearts contain similar scar tissue. Their results, published today in eLife, could help identify the best treatments for people who might be at risk of recurrent stroke, new heart disorders, or both.
Doctors treating babies born with Turner syndrome need to look for heart rhythm abnormalities, in addition to the usual heart problems of high blood pressure or left-sided structural heart defects, according to Meena Bolourchi, MD, assistant professor of pediatrics at Boston University School of Medicine.
Researchers from Belgium, the Netherlands, Russia, and Italy have developed a breakthrough method for quickly, accurately, and reliably diagnosing cardiac arrhythmias.
Management and outcomes of adults with atrial fibrillation are presented today at EHRA 2021, an online scientific congress of the European Society of Cardiology. The document is published in EP Europace, a journal of the ESC.
A tsunami of chronic health conditions as a result of the SARS-CoV-2 pandemic, especially cardiometabolic disease, may produce an enormous wave of death and disability that demands immediate, comprehensive strategies.
Abnormal heart rhythms-; cardiac arrhythmias-; are a major worldwide health problem. Now scientists are using ultrasound for more accurate maps of arrhythmic sites in the heart for the improved success of ablation procedures.
Exposure to SARS-Co-V2, the virus that causes COVID-19, can put otherwise healthy children and adolescents at risk for Multisystem Inflammatory Syndrome in Children (MIS-C), a rare but possibly life-threatening pediatric condition that can cause severe inflammation in organs like the heart, brain, lungs, kidneys and gastrointestinal system.
A team of scientists from Geisinger and Tempus have found that artificial intelligence can predict risk of new atrial fibrillation (AF) and AF-related stroke.
COVID-19, the disease caused by the pandemic coronavirus SARS-CoV-2, is primarily regarded as a respiratory infection. Yet the virus has also become known for affecting other parts of the body in ways not as well understood, sometimes with longer-term consequences, such as heart arrhythmia, fatigue and "brain fog."
Researchers have used the zebrafish (Danio rerio) to identify the role of a gene involved in cardiac rhythm, which could help explain the fundamentals of what it takes to make a human heartbeat.
Canadian researchers are the first to study how different patterns in the way older adults walk could more accurately diagnose different types of dementia and identify Alzheimer's disease.
Structural racism is a public health crisis in the U.S. and worldwide. The scientific publishing community can improve our understanding and address the significant health impacts of structural racism in racial and ethnic disparities research.
Researchers from Mayo Clinic and AliveCor Inc. have been using artificial intelligence (AI) to develop a mobile device that can identify certain patients at risk of sudden cardiac death.
There could be an intervention on the horizon to help prevent heart damage caused by the common chemotherapy drug doxorubicin, new research suggests.
onditions causing arrhythmia are among the most common cardiac conditions. A study headed by Prof. Georg Schmidt of the Technical University of Munich has demonstrated for the first time that the nocturnal respiratory rate can help with an important prediction: It is an indicator of whether a defibrillator will help to extend the life of patients with arrhythmia.
Columbia researchers have created a new technology using synthetic llama antibodies to prevent specific proteins from being destroyed inside cells.
Special activity trackers can be used to fairly accurately determine the respiratory rate of people while they sleep.
The American Heart Association and the American College of Cardiology today released an updated guideline for managing patients with hypertrophic cardiomyopathy (HCM).
