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.
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.
Scientists at Johns Hopkins have successfully created personalized digital replicas of the upper chambers of the heart and used them to guide the precise treatment of patients suffering from persistent irregular heartbeats.
Thin, flexible fibers made of carbon nanotubes have now proven able to bridge damaged heart tissues and deliver the electrical signals needed to keep those hearts beating.
One of the most common problems cardiologists handle is atrial fibrillation, also called AFib or AF. AFib is an abnormal or irregular heartbeat that can lead to blood clots, stroke, heart failure and other heart-related complications.
Calling an ambulance during an emergency, emailing a breaking news or journal article before a 5 p.m. deadline and maintaining conditions during the fifth week of a 6-week lab study, without altering the light or temperature, requires electricity and translates into time, money and lives
Australian researchers have unlocked the mystery as to why the chemotherapy drug 5-Fluorouracil is not effective at treating certain cancers.
Researchers at Boston Children's Hospital report creating the first human tissue model of an inherited heart arrhythmia, replicating two patients' abnormal heart rhythms in a dish, and then suppressing the arrhythmia with gene therapy in a mouse model.
Researchers have developed a new and easier method of detecting irregular heart rhythms such as Atrial Fibrillation (AF or AFib) after a stroke. At present clinical rely upon standard cardiac telemetry to detect AF seen commonly after a stroke.
Hesperos Inc., pioneers of the "human-on-a-chip" in vitro system has announced the use of its innovative multi-organ model to successfully measure the concentration and metabolism of two known cardiotoxic small molecules over time, to accurately describe the drug behavior and toxic effects in vivo.
Atrial fibrillation is a condition that produces an irregular heartbeat that affects about two percent of the general population and six percent of people over 65 years of age.
More than half of patients with relapsed multiple myeloma treated with carfilzomib experienced cardiac issues during treatment, according to a multi-institutional study published June 12 in Journal of Clinical Oncology.
Canadian researchers followed their intuition that a drug initially intended for heart failure could be effective in treating cancer. Those efforts have borne fruit, as demonstrated by their work published in the Journal of Experimental and Clinical Cancer Research.
Obstructive sleep apnea is a common condition that has been associated with increased mortality, especially in individuals who have cardiac arrhythmia. A University of Arizona physician-scientist has received a grant to try to find out why.
Women have long been told fainting is a common but harmless symptom of pregnancy, but new research shows it may indicate issues for both the baby and mother's health, especially when it occurs during the first trimester.
