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.
Triggers of acute heart failure vary globally, according to late breaking results from the REPORT-HF registry presented today at Heart Failure 2018 and the World Congress on Acute Heart Failure, a European Society of Cardiology Congress.
Prostate cancer is the most common cancer in men in the US. As the prostate is a testosterone-responsive gland, androgen deprivation therapy is the cornerstone of treatment in these men, with approximately 50 percent of prostate cancer patients starting ADT within a year of diagnosis.
Researchers at University of California San Diego School of Medicine and their collaborators have developed a technique that allows them to speed up or slow down human heart cells growing in a dish on command -; simply by shining a light on them and varying its intensity.
Atrial fibrillation patients who are diagnosed with carotid artery disease face higher risks for developing dementia, according to new research from the Intermountain Medical Center Heart Institute in Salt Lake City.
The family history questions asked during patient assessments are becoming even more important with the rise of precision medicine and genetic testing.
A new study is the first to validate the accuracy of wrist-worn wearable devices in measuring induced paroxysmal supraventricular tachycardia (PSVT), or episodes of rapid heart rate.
University of Illinois at Chicago researchers have discovered a way turn pluripotent stem cells into atrial cells, which make up the upper chambers, or atria, of the heart. The discovery will enable them to better study atrial fibrillation, the most common heart rhythm disorder also known as AFib, which originates in the heart's atria.
With an increasing level of noise, the incidence of atrial fibrillation also increases dramatically. Scientists from the Department of Cardiology at the Mainz University Medical Center were able to prove this with data from the Gutenberg Health Study.
A medicinal plant frequently used in Traditional Chinese Medicine (TCM) - Evodia rutaecarpa - contains substances that can cause cardiac arrhythmia. This is what researchers from the Universities of Basel, Vienna and Utrecht have recently found out.
You've heard of "nature versus nurture," and philosophers argue about which is more important. But how does this work on the cellular level?
Heart disease is a major global health problem--myocardial infarction annually affects more than one million people in the U.S. alone, and there is still no effective treatment.
The Ohio State University Wexner Medical Center will establish the nation's first center dedicated to treating those with heart failure and arrhythmia with gifts totaling $18 million from Bob and Corrine Frick.
Researchers from the longevity biotech company GERO and Moscow Institute of Physics and Technology have shown that physical activity data acquired from wearables can be used to produce digital biomarkers of aging and frailty.
A study has shown that depression may be a risk factor for atrial fibrillation, a common heart rhythm disorder that can cause clot formation and stroke.
The heart is capable of terminating arrhythmias itself after local gene therapy, potentially avoiding the need for patients to undergo painful electric shocks, according to a proof-of-concept study presented today at EHRA 2018, a European Society of Cardiology congress.
Patients with atrial fibrillation could reduce the risk of dementia by taking stroke prevention medications, according to recommendations published online today in EP Europace, a European Society of Cardiology journal, and presented at EHRA 2018.
In the event of a cardiorespiratory arrest, two actions are crucial for the patient's survival: cardiopulmonary resuscitation and defibrillation.
Johnson & Johnson Medical Devices Companies announced today that Biosense Webster, Inc., a worldwide leader in the diagnosis and treatment of heart arrhythmias, enrolled and treated the first patient in its SHINE clinical study in Europe.
Johnson & Johnson Medical Devices Companies announced today that Biosense Webster, Inc., a worldwide leader in the diagnosis and treatment of heart arrhythmias, has completed patient enrollment in its U.S. Investigational Device Exemption study of the THERMOCOOL SMARTTOUCH SF Catheter.
To prevent cardiac death, people with certain cardiac disorders are implanted with electronic devices designed to automatically stimulate the heartbeat or counteract serious arrhythmia if necessary.
