Arrhythmia News and Research

RSS

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.

Study: Hydroxychloroquine has no effect on abnormal heart rhythm in lupus patients with CKD

New research shows that adults with lupus who take the antimalarial drug, hydroxychloroquine, do not have any differences in their corrected QT (QTc) intervals, an electrocardiogram (EKG) measurement of the heart's electrical signals, even if they have chronic kidney disease (CKD), a complication of lupus that can be associated with increased levels of the medication.

Hydroxychloroquine not associated with prolonged heart rhythm intervals in RA or lupus patients

New research presented at ACR Convergence, the American College of Rheumatology's annual meeting, discovers that use of hydroxychloroquine, a generic drug, does not cause any significant differences in QTc length or prolonged QTc, key measures of heart rate, in people with rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE).

Correlations found between 'long-COVID' patients and preexisting health conditions

Researchers from the nference (a biotech information firm) in Cambridge, MA, USA, the Mayo Clinic in Rochester, MN, USA, and nference Labs based in Bengaluru, India, recently performed a retrospective analysis of 266 COVID-19 patients.

Rubbery bioelectronic cardiac patch can monitor and treat heart disease

Pacemakers and other implantable cardiac devices used to monitor and treat arrhythmias and other heart problems have generally had one of two drawbacks - they are made with rigid materials that can't move to accommodate a beating heart, or they are made from soft materials that can collect only a limited amount of information.

New machine learning-based approach helps detect atrial fibrillation drivers

Researchers from Skoltech and their US colleagues have designed a new machine learning-based approach for detecting atrial fibrillation drivers, small patches of the heart muscle that are hypothesized to cause this most common type of cardiac arrhythmia.

Study: Care from multidisciplinary cardio-obstetrics team may improve pregnancy outcomes

Cardiovascular disease is now the number one cause of maternal mortality in the United States, but a new study suggests that care from a multidisciplinary cardio-obstetrics team may improve pregnancy outcomes and reduce hospital readmission rates.

More than 2.5 million person-years of life lost in US due to COVID-19

In a recently published study, researcher Stephen Elledge from Harvard Medical School has described converting the coronavirus disease (COVID-19) death toll from individual deaths to “person-years” lost in order to provide a more accurate picture of the pandemic’s toll on the population.

Exosomes yield regenerative benefits equivalent to hiPSC-CCs, shows study

Science has long known that recovery from experimental heart attacks is improved by injection of a mixture of heart muscle cells, endothelial cells and smooth muscle cells, yet results have been limited by poor engraftment and retention, and researchers worry about potential tumorigenesis and heart arrhythmia.

Cardiac arrhythmias linked to functional and structural consequences of gene mutations

Life-threatening cardiac arrhythmias can be linked to the functional and structural consequences of gene mutations. The study is published in the peer-reviewed journal Bioelectricity.

Identifying, preventing and treating drug-induced arrhythmias

Health care professionals should become more familiar with medications that cause irregular heart rhythms called arrhythmias, according to "Drug- Induced Arrhythmias," a new scientific statement from the American Heart Association, published today in the Association's flagship journal Circulation.

COVID-19 patients may experience long-term cardiovascular complications

Researchers at the University of Washington in Seattle have conducted a study suggesting that infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can directly infect heart tissue and contribute to whole-organ cardiac dysfunction.

Evidence of SARS-CoV-2 coronavirus particles in heart tissue

Researchers in Milan, Italy, have identified the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the heart tissue of deceased coronavirus disease 2019 (COVID-19) patients who had died from respiratory failure, without showing any signs of cardiac involvement.

People with atrial fibrillation are urged to quit smoking

Scientists today urged people with atrial fibrillation - the most common heart rhythm disorder - to kick the habit and cut their stroke risk. The research is presented today at ESC Congress 2020.1

Researchers investigate why irregular heartbeats occur after stem cell transplantation

Stem cells are heavily studied around the world with the hope to revive damaged body parts unable to regenerate itself. Injured heart muscles are one of these areas which remain impaired in adults who have experienced heart attacks.

Self-measurements using fitness watches generate insecurity and anxiousness

How does measuring our sleep, exercise and heart rates using various apps and fitness watches affect us? Self-quantifying may better the understanding of our individual health, but according to a new study, it also gives rise to anxiety.

AI-enabled ECG provides a rapid and effective method to screen heart failure

When people seek emergency care for shortness of breath, a routine electrocardiogram (ECG or EKG) enhanced by artificial intelligence (AI) is better than standard blood tests at determining if the cause is heart failure, according to new research published today in Circulation: Arrhythmia and Electrophysiology, an American Heart Association journal.

Researchers initiate multiple studies to identify coronavirus-related heart problems

COVID-19 is shown to impact the heart and, in some cases, have long-lasting cardiac effects. To discover the extent to which COVID-19 affects the heart, cardiologists and researchers with the University of Miami Miller School of Medicine have begun multiple studies.
