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.
Harvard University researchers have bioengineered a three-dimensional model of a human left heart ventricle that could be used to study diseases, test drugs and develop patient-specific treatments for heart conditions such as arrhythmia.
New evidence published today shows there is little or no effect of omega 3 supplements on our risk of experiencing heart disease, stroke or death.
The more you smoke, the greater your risk of a heart rhythm disorder called atrial fibrillation. That's the finding of a study published today in the European Journal of Preventive Cardiology, a European Society of Cardiology (ESC) journal.(1)
Toyoda Gosei Co., Ltd. and EBM Corporation have developed a prototype "Super BEAT" surgical training simulator that can reproduce the beating of the heart with extreme accuracy using e-Rubber, an artificial muscle that functions with electricity.
People with irregular heartbeat due to a condition called atrial fibrillation, are often prescribed blood thinners to reduce the risk of blood clots that can cause a stroke.
Using catheter-based ablation instead of medications alone reduces the risks of death and stroke in patients with the common form of heart arrhythmia known as atrial fibrillation, or AFib, new research from UC Davis physicians shows.
Clinical laboratories often rely on medical articles and public information on gene disease associations in determining the genes to include on genetic testing panels for specific conditions or the specific results to return to patients.
Investigators at Children's Hospital Los Angeles and the University of Southern California have demonstrated the feasibility of implanting a micropacemaker system in the pericardial sac surrounding the heart -- a breakthrough that may open up new cardiac pacing options for children and adults.
Wearable defibrillators may be a safe and effective alternative to surgically implanted devices among children with ventricular arrythmias that increase the risk of sudden cardiac death, according to a new study.
Merck, known as MSD outside the United States and Canada, today announced that the U.S. Food and Drug Administration has accepted for standard review a new supplemental Biologics License Application for KEYTRUDA, Merck's anti-PD-1 therapy, as adjuvant therapy in the treatment of patients with resected, high-risk stage III melanoma and granted a Prescription Drug User Fee Act, or target action, date of February 16, 2019.
A new study by Professors Martti Juhola and Katriina Aalto-Setälä of the University of Tampere in Finland demonstrates that with the use of artificial intelligence and machine learning, it is possible not only to accurately sort sick cardiac cell cultures from healthy ones, but also to differentiate between genetic cardiac diseases.
Scientists have developed an algorithm that predicts potentially dangerous low blood pressure, or hypotension, that can occur during surgery.
A collaborative research team is on a quest to collapse a tiny pocket between cardiac cells that can cause big problems. Called the perinexus, the structure spans only tenths of a millimeter -- all the space it needs to disrupt a person's heartbeat.
Interfering with inflammatory signals produced by heart muscle cells might someday provide novel therapeutic strategies for atrial fibrillation, according to an international team of researchers who have published their findings in the journal Circulation.
Triggers of acute heart failure vary globally, according to late breaking results from the REPORT-HF registry presented today at Heart Failure 2018 and the World Congress on Acute Heart Failure, a European Society of Cardiology Congress.
Prostate cancer is the most common cancer in men in the US. As the prostate is a testosterone-responsive gland, androgen deprivation therapy is the cornerstone of treatment in these men, with approximately 50 percent of prostate cancer patients starting ADT within a year of diagnosis.
Researchers at University of California San Diego School of Medicine and their collaborators have developed a technique that allows them to speed up or slow down human heart cells growing in a dish on command -; simply by shining a light on them and varying its intensity.
Atrial fibrillation patients who are diagnosed with carotid artery disease face higher risks for developing dementia, according to new research from the Intermountain Medical Center Heart Institute in Salt Lake City.
The family history questions asked during patient assessments are becoming even more important with the rise of precision medicine and genetic testing.
A new study is the first to validate the accuracy of wrist-worn wearable devices in measuring induced paroxysmal supraventricular tachycardia (PSVT), or episodes of rapid heart rate.
