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.
Cardiologists at The Ohio State University Wexner Medical Center are the first in the United States to test a new type of ablation technology for patients suffering from atrial fibrillation, a common type of irregular heartbeat.
For most people, the benefits of aerobic exercise far outweigh the risks, however, extreme endurance exercise - such as participation in marathons and triathlons for people who aren't accustomed to high-intensity exercise - can raise the risk of sudden cardiac arrest, atrial fibrillation (a heart rhythm disorder) or heart attacks, according to a new Scientific Statement "Exercise-Related Acute Cardiovascular Events and Potential Deleterious Adaptations Following Long-Term Exercise Training: Placing the Risks Into Perspective-An Update from the American Heart Association," published today in the Association's premier journal Circulation.
A group of researchers led by Professor Yoshiki SAWA of the Cardiovascular Group in the Graduate School of Medicine, Osaka University, succeeded in beating-heart surgery to repair a mitral valve.
A new study published in the journal BMJ in February 2020 reports that macrolide or penicillin antibiotic consumption in pregnancy could be linked to several adverse health outcomes in children. These include major malformations, cerebral palsy, attention deficit hyperactivity disorder, and autism spectrum disorder.
People may feel a flip-flop in their chest when they're under stress, haven't slept well or even during normal activity.
Low oxygen levels in the heart have long been known to produce life-threatening arrhythmias, even sudden death. Until now, it was not clear how.
An approach based on artificial intelligence may allow EKGs to be used to screen for hypertrophic cardiomyopathy in the future.
Cardiomyopathy refers to diseases of the heart muscle causing cardiac myocyte injury and myocardial dysfunction, which impair structural and functional ventricular filling or ejection of blood in the absence of other structural or vascular heart diseases.
The A143T variant of the GLA gene is associated with an increased risk of Fabry cardiomyopathy, according to a new study.
Duchenne type muscular dystrophy is the most common hereditary muscular disease among children, leaving them wheelchair-bound before the age of twelve and reducing life expectancy.
A panel of experts have said that nine genes linked to a dangerous heart disorder called long QT syndrome, are not associated with the condition.
Researchers from the Faculty of Health and Medical Sciences have shown a possible link between a genetic variation and the widespread type of cardiac arrhythmia, atrial fibrillation.
Around 26 million people worldwide suffer from heart failure, with more than 50 per cent dying suddenly most likely due to the spontaneous onset of a heart rhythm problem, known as an arrhythmia.
Marijuana use is rising steadily across the US as more and more states enact laws making it a legal recreational and medicinal agent. However, a new study underlines the fact that this is, in fact, playing with an unknown substance, which may cause serious bodily harm. The review article, published in the Journal of the American College of Cardiology, shows that more than 2 million adults who currently have heart or vascular disease gave a history of being currently on marijuana products, or having used them in the past.
A team led by investigators at Brigham and Women's Hospital has stated that cardiology patients should be warned and counseled about the potential risks of using marijuana until further evidence is available.
A new study published in January 2020 in the European Journal of Preventive Cardiology shows that burnout could really cause your heart to fail as a result of an abnormal heart rhythm called atrial fibrillation (AF).
A loved one suffering cardiac arrest is an emotionally stressful time for families, but never more so than when the patient is a child. The very real potential for loss of life in these situations means that the way in which emergency responders treat out of hospital cardiac arrest (OHCA) becomes even more crucial when dealing with pediatric patients.
Prolonged cardiac rhythm monitoring will improve arrhythmia diagnostic yield among non-low-risk emergency department patients with syncope.
Heart disease remains the largest killer in Australia and around the world. A new study has shown that a protein therapy- recombinant human platelet-derived growth factor-AB (rhPDGF-AB) - could improve outcomes following heart attack.
Researchers have found that molecular origins of a heart beat. They have found the proteins that make up tiny sodium channels in the tissues of the heart that can help generate the heart beats. The results of the study titled, “Structure of the Cardiac Sodium Channel” was published yesterday 19th of December 2019 in the journal Cell.
