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.
UC San Diego Sulpizio Cardiovascular Center is now offering patients with atrial fibrillation the breakthrough benefits of heat energy, or radio frequency waves, to irreversibly alter heart tissue that triggers an abnormal heart rhythm or arrhythmia.
Blood tests have been a mainstay of diagnostic medicine since the late 19th century, offering a wealth of information concerning health and disease. Nevertheless, blood derived from the human umbilical cord has yet to be fully mined for its vital health information, according to Rolf Halden, a researcher at Arizona State University's Biodesign Institute.
Heart disease tragically affects almost every family in the United States. It claimed more than 616,000 lives in 2008, the latest year for which statistics are available. Coronary artery disease is the most common type of heart disease and can lead to heart attacks, heart failure, strokes, arrhythmia and angina.
New research from Western University, Canada, has demonstrated the benefits of performing Cardiovascular Magnetic Resonance (CMR) in cases where patients have been resuscitated after Sudden Cardiac Death or enter hospital suffering from ventricular arrhythmias.
That flutter in your heart may have more to do with the movement of sodium ions than the glance of a certain someone across a crowded room.
Up to 45,000 sudden cardiac arrests occur each year in Canada, and less than five percent survive. In some of these cases, the event cannot be explained by the presence of underlying heart disease. In order to identify people at risk of these unexplained cardiac events, a newly published study examined the presence of certain warning symptoms that are present in people who have been resuscitated from a cardiac arrest.
A drug used to treat multiple sclerosis may also be effective at preventing and reversing the leading cause of heart attack, a new study has found.
Everist Genomics announced today that Executive Vice Chairman Alex Charlton will speak about its breakthrough CardioDefender Device at the Wearable Technologies Conference, January 30, 2012, in Munich.
A study has shown that there is a sharp rise in the number of people who report heart problems, tremors and chest pains after drinking caffeinated energy drinks. The incidences are particularly common among teenagers. Close to 300 calls were made to NSW's poisons centre regarding adverse reactions to energy drinks between January 2004 and the end of 2010, with more than a third of people attending hospital.
Researchers in Rhode Island Hospital's Cardiovascular Research Center have published two new studies focusing on the causes of arrhythmia and sudden cardiac death (SCD) when a genetic disorder is present.
Stereotaxis, Inc. today announced the completion of the first 50 clinical procedures using the Company's new Niobe ES system to treat patients with a variety of complex cardiac arrhythmias. A majority of the first 50 cases were performed to treat atrial fibrillation (AF), the most common type of cardiac arrhythmia.
In a study published in the Dec. 26, 2011, Proceedings of the National Academy of Sciences early edition, researchers led by the University of Utah showed the CCS is extremely sensitive to levels of Tbx3. Mouse embryos with Tbx3 levels below a critical threshold suffered arrhythmia and couldn't survive. As the levels of Tbx3 were increased, mice survived to birth, but as adults they developed arrhythmias or had sudden death.
What do sweaty palms and abnormal heart rhythms have in common? Both can be initiated by the nervous system during adrenaline-driven "flight or fight" stress reaction when the body senses danger.
Dr. Rabab Mohsin, an internal medicine resident at the University of Kentucky, working with Dr. Alison Bailey of the University of Kentucky Gill Heart Institute, has discovered that the drug warfarin was underutilized in a large study group of women.
Thanks to a new study from Columbia Engineering School, doctors may now be able to diagnose in their offices non-periodic arrhythmias-noninvasively and at low cost-within a single heartbeat. Non-periodic arrhythmias include atrial and ventricular fibrillation, which are associated with severely abnormal heart rhythm that can in some cases be life-threatening.
Estech, a leader in minimally invasive cardiac surgery, announced today that the first three patients have been enrolled in the HISTORIC-AF European multi-center staged hybrid ablation clinical study.
Bristol-Myers Squibb Company and Pfizer Inc. today announced that the U.S. Food and Drug Administration (FDA) has accepted for review a New Drug Application (NDA) for ELIQUIS® (apixaban), an investigational compound for the prevention of stroke and systemic embolism in patients with atrial fibrillation.
Case Western Reserve University School of Medicine has received a $3.8 million grant from the National Heart, Lung, and Blood Institute (NHLBI) to study sleep apnea as a possible cause of atrial fibrillation (AF), the most commonly diagnosed type of arrhythmia, or irregular heart rhythm.
At the world's largest medical trade fair, Medica 2011 held in Düsseldorf last week, CardioComm Solutions, Inc. demonstrated their newly developed remote patient ECG monitoring service, called HeartCheck Smart Monitoring
IntriCon Corporation, a designer, developer, manufacturer and distributor of miniature and micro-miniature body-worn devices, today announced it has received 510(k) marketing clearance from the U.S. Food and Drug Administration (FDA), for its Sirona Event and Holter Recorder. Sirona is the company's second-generation cardiac diagnostic monitoring (CDM) device, allowing physicians to monitor patient cardiac events remotely.
