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.
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.
Atomic-level studies of the architecture of tiny sodium channel proteins, critical to generating electrical signals that start off each beat of the heart, are imparting striking details about their function, malfunctions, disruption by many disease mutations, and response to medication.
Patients with atrial fibrillation, the most frequent cardiac arrhythmia, are closer to accessing personalized medicine.
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.
