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.

Compound in pickled capers can directly regulate proteins required for bodily processes

A compound commonly found in pickled capers has been shown to activate proteins required for normal human brain and heart activity, and may even lead to future therapies for the treatment of epilepsy and abnormal heart rhythms.

Researchers caution use of chloroquine therapy for patients at higher risk of heart rhythm abnormalities

A patient who met many of the published safety guidelines for chloroquine therapy against COVID-19 was observed to have a very abnormal ECG pattern after treatment began, leading to multiple episodes of torsade de pointes (TdP), a life-threatening arrhythmia in which the lower chambers of the heart beat out of sync with the upper chambers.

Genetic marker may predispose African Americans to cardiac complications from COVID-19

Nearly one out of every 10 African Americans has a genetic variant that puts them inherently at an increased risk for ventricular arrhythmias and sudden cardiac death.

Experts outline best way to predict common heart rhythm disorders

Use the right tool for the job. Today experts outline the best way to identify people most likely to develop common and devastating heart rhythm disorders.

Researchers use optical mapping system to observe the effect of hydroxychloroquine

The malaria drug hydroxychloroquine, which has been promoted as a potential treatment for Covid-19, is known to have potentially serious effects on heart rhythms.

Meta-analysis of latest second-line treatments for status epilepticus

Status epilepticus (SE) is the most common neurologic emergency, with rates estimated between 1.3 and 81 cases per 100,000 people per year.

Treatment with chloroquine or hydroxychloroquine offers no benefit for COVID-19 patients

A large observational study suggests that treatment with the antimalarial drug chloroquine or its analog hydroxychloroquine (taken with or without the antibiotics azithromycin or clarithromycin) offers no benefit for patients with COVID-19.

Doctoral candidate receives NIH fellowship to study how adenovirus affects heart function

A dose of adenovirus hits most people like a common cold - a cough, a fever, maybe a sore throat. But for an unfortunate few, the usually benign bug hacks the heart's cellular electrical communication system and sometimes proves fatal.

New mathematical model to study the behavior of the human heart

Having now reached its third year, Project "iHEART" of Politecnico di Milano, winner of an ERC Advanced Grant of euro 2,350,000, has set itself the ambitious goal of creating a complete mathematical model to study the behavior of the human heart and of its pathologies, a sort of "virtual microscope."

Using supercomputers to screen drugs for deadly heart arrhythmias

Death from sudden cardiac arrest makes headlines when it strikes athletes. But it also causes the most deaths by natural causes in the U.S. estimated at 325,000 per year.

Diastolic dysfunction associated with increased risk for arrhythmic death

Sudden cardiac death is a common cause of death in patients with reduced systolic ejection function. As part of a long-term observational study, MedUni Vienna researchers from the Division of Cardiology have now shown the importance of the diastolic filling function: the less the heart fills when there is diastolic dysfunction, the more likely patients are to die suddenly of cardiac arrhythmia.

Hydroxychloroquine combined with azithromycin and abnormal heart rhythms in COVID-19 patients

A new study shows that the initially lauded combination of drugs against COVID-19 - Hydroxychloroquine and Chloroquine combined with azithromycin, could lead to abnormal and life-threatening heart rhythms. In patients hospitalized with the novel coronavirus infection or SARS CoV-2, this combination can lead to prolonged QT interval as can be detected on ECG.
