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.
Atrial fibrillation, also known as AFib, is the most common type of irregular heartbeat, and it is associated with increased mortality. While researchers have identified a causal link between obesity and AFib, the underlying mechanism of how obesity contributes to the heart arrhythmia is still unknown.
Genetic studies spanning three generations of a Persian Jewish family by researchers at Ben-Gurion University of the Negev. have identified a gene that causes nighttime atrial fibrillation (AFib).
More than 220,000 American adults die suddenly of cardiac causes – a phenomenon called sudden cardiac death. Some sources put it as closer to 400,000. Both inexplicable and distressing, this has been the subject of a new study published in the Journal of the American College of Cardiology and presented at the American Heart Association’s scientific session.
A new study published in the Journal of Physiology on November 14, 2019, reports the development of a radically different type of cardiac pacemaker which could change the prognosis of patients with heart failure.
The success of antiretroviral therapies has extended the lives of people living with HIV, long enough for other chronic health conditions to emerge, including a recently documented uptick in sudden death.
Size may matter when it comes to having a safe and steady heart. A new study shows tall people are more likely to develop from an irregular heartbeat, known as atrial fibrillation (AFib).
It was widely accepted that putting the newborn baby on the mother’s chest promotes skin-to-skin contact and bonding between the two who share the common experience of birth, and enhances the chances of successful breastfeeding, after a Cesarean section. However, from the viewpoint of anesthesiologists, who oversee the critical part of keeping the mother pain-free yet healthy during the surgical procedure, this introduces unnecessary risks.
Atrial fibrillation is the most common heart arrhythmia in humans. This condition increases the risk of heart failure, stroke, dementia and death, and current treatments have suboptimal efficacy and carry side effects.
The Bristol-Myers Squibb-Pfizer Alliance and Fitbit today announced at the TIME 100 Health Summit in New York that they are working together to help drive timely diagnosis of atrial fibrillation (AFib) with the aim of improving earlier detection in individuals at increased risk of stroke.
Digital simulations of human organs can be used to study the development of diseases and to customize therapies for patients.
Treating high-risk heart patients with a single, high dose of radiation therapy can dramatically reduce episodes of rapid, abnormal heartbeats for more than two years, offering hope to patients who have exhausted other treatment options.
A single high dose of radiation aimed at the heart significantly reduces episodes of a potentially deadly rapid heart rhythm, according to results of a phase one/two study at Washington University School of Medicine in St. Louis.
A new study presented at this year's Annual Meeting of the European Association for the Study of Diabetes in Barcelona, Spain (16-20 Sept) shows that men and women experience different comorbidities (other diseases at the same time) as having diabetes or prediabetes, as well as an unexpectedly high rate of prediabetes among children aged 6-10 years.
A new study has reported success in identifying severe heart failure in 100% of cases using a single heartbeat recording from an electrocardiogram (ECG).
A new study has shown that mobile health (mHealth) devices are able to screen for the common cardiac disorder called atrial fibrillation (AF).
Implantable brain electrodes have been around for quite some time now, both for diagnosing and treating neuropsychiatric conditions like Parkinson’s disease. However, one limitation of conventional probes is their size and rigidity, compared to the soft, gelatinous consistency of the brain.
Implantable cardioverter-defibrillator use is associated with reduced short- and long-term mortality in patients with heart failure, according to late-breaking research presented in a Hot Line Session today at ESC Congress 2019 together with the World Congress of Cardiology and published in Circulation.
In the near future, doctors may be able to apply artificial intelligence to electrocardiogram data in order to measure overall health status, according to new research published in Circulation: Arrhythmia and Electrophysiology, a journal of the American Heart Association.
If there could be one organ in the body that works 24/7 nonstop and makes sure the cells get the oxygen and nutrients they need, it’s the heart. The heart also needs its supply of blood rich in oxygen, and in the event, it doesn’t receive adequate amounts of blood, it can suffer serious complications. Atrial fibrillation, for one, is an irregular heartbeat that affects blood flow to the heart muscle and the rest of the body.
Over the last few decades, medical progress has led to the survival of many more people with cancer. However, a new study published in The Lancet shows that this cohort has a higher risk of cardiovascular disease (CVD) than controls without cancer, due to a number of reasons.
