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.
Boston Scientific Corporation announces the exercise of its option to acquire Cameron Health, Inc., a privately held company based in San Clemente, California.
As part of its continued commitment to ADHD research, Shire plc, the global specialty biopharmaceutical company, today announced it is initiating two Phase 4 clinical trials to compare Vyvanse (lisdexamfetamine dimesylate) Capsules, (CII) to Concerta (methylphenidate HCl) Extended-Release Tablets.
Pediatric cardiology researchers and clinicians from almost 50 centers from across the U.S. and around the world are gathering at the Cardiology 2012 Conference sponsored by The Children's Hospital of Philadelphia on Feb. 22-26 in Orlando, Fla.
How much calcium could a hibernating woodchuck's heart cells sequester, if a hibernating woodchuck's heart cells could sequester calcium? More than enough, it turns out, to protect the animals from cardiac arrhythmias - abnormal heart rhythms such as ventricular tachycardia and ventricular fibrillation that can lead to sudden cardiac death - according to a new study of the hibernating animals that may provide insight into arrhythmia therapies.
Researchers have found that a biological clock can influence a heart attack. The risk of “sudden cardiac death” peaks in the morning and rises again in the evening as shown in lab animals.
Dr. Ali Gheissari of Los Angeles, CA has been ranked among the top physicians in the nation based on patient reviews.
A fundamental discovery reported in the March 1st issue of the journal Nature, uncovers the first molecular evidence linking the body's natural circadian rhythms to sudden cardiac death (SCD). Ventricular arrhythmias, or abnormal heart rhythms, are the most common cause of sudden cardiac death: the primary cause of death from heart disease.
For the first time in a new U.S. clinical trial, researchers at Mount Sinai School of Medicine have used the HeartLight Endoscopic Ablation System (EAS) to correct abnormal electrical signals inside the heart of a patient affected by atrial fibrillation (AFib), one of the nation's most common heart ailments.
What we perceive as the beating of our heart is actually the co-ordinated action of more than a billion muscle cells. Most of the time, only the muscle cells from the larger heart chambers contract and relax. But when the heart needs to work harder it relies on back-up from the atrial muscle cells deep within the smaller chambers (atria) of the heart.
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.
