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.
The Milken Institute Center for Strategic Philanthropy, in partnership with the Ann Theodore Foundation (ATF), is pleased to announce a new Request for Proposals (RFP) focused on understanding the underlying biology of sarcoidosis, an immune dysregulation condition.
Breathing particulate matter (i.e., tiny particles suspended in the air) air pollution may trigger irregular heart rhythms (arrhythmias) in healthy teenagers, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.
Researchers at Johns Hopkins Medicine report that an experimental drug first developed to treat kidney disease prolongs survival and improves muscle function in mice genetically engineered to develop a severe form of Duchenne muscular dystrophy (DMD).
A recent study determines the relationship between COVID-19 severity and risk of subsequent cardiovascular events in a large cohort.
Researchers monitored the safety of the four diverse SARS-CoV-2 vaccines approved by the EMA and MHRA in 2020 to 2021.
Cannabis prescribed for chronic pain is associated with an elevated risk of heart rhythm disorders, according to research presented at ESC Congress 2022.
Understanding how drugs used to treat malaria impact the human heart is essential to finally toppling one of the world's most common but serious infections, according to researchers at the University of Surrey.
Screening individuals for atrial fibrillation (AF) using wearable devices is more cost-effective than screening using conventional methods such as 12-lead electrocardiogram (ECG) and pulse palpation, or than no screening at all, researchers from Massachusetts General Hospital (MGH) have found.
Scientists from the National University of Singapore Department of Pharmacy have developed an improved pharmaceutical drug for the treatment of the most common heart rhythm disturbance – atrial fibrillation (AF).
A spiral wave of electrical activity in the heart can cause catastrophic consequences. One spiral wave creates tachycardia -; a heart rate that's too fast -; and multiple spirals cause a state of disorganized contraction known as fibrillation.
Results from one of the largest global studies of atrial fibrillation (AFib) procedures show that the simple approach is usually best when it comes to ablation, a procedure where physicians destroy or ablate cardiac tissue to correct irregular heart rhythms.
Transition to middle school can be a stressful time for adolescents. They must adjust to a new peer group and social environment while going through the developmental changes of puberty.
New research from the Victor Chang Cardiac Research Institute will allow families around the world to discover if they are carrying genetic mutations that cause sudden cardiac arrest – a condition that kills nine out of 10 victims.
Testosterone replacement therapy appears safe in the short-to-medium term to treat a condition caused by deficiency of the male sex hormone, according to the most comprehensive analysis of the treatment to date, published in The Lancet Healthy Longevity journal.
Axol Bioscience Ltd. (Axol), an established provider of iPSC-derived cells, media, and characterization services for life science discovery, today announced that its human induced pluripotent stem cell (iPSC)-derived ventricular cardiomyocytes have undergone comprehensive in vitro pro-arrhythmia assay (CiPA) validation.
Last summer, Northwestern University scientists introduced the first-ever transient pacemaker — a fully implantable, wireless device that harmlessly dissolves in the body after it's no longer needed.
In a recent study published in the journal Nature Cardiovascular Research, researchers used deep learning (DL) assessment of the scarring in the heart to predict arrhythmia-associated sudden death survival.
Life-threatening arrhythmias are more common on days with highly polluted air, according to research presented today at Heart Failure 2022, a scientific congress of the European Society of Cardiology.
Herbal supplements may be natural, but that does not mean they are always safe. A new case report appearing in Heart Rhythm Case Reports, an official journal of the Heart Rhythm Society, published by Elsevier, is a case in point.
Following a heart attack, the human body is incapable of repairing lost tissue due to the heart's inability to generate new muscle.
