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.
For decades, doctors have understood that microbes in the human gut can influence how certain drugs work in the body - by either activating or inactivating specific compounds, but questions have long remained about exactly how the process works.
Millions of children worldwide live on the streets. A review and analysis of 50 studies on substance abuse by street children in 22 resource-constrained countries has found lifetime substance use to be both common and high, posing serious threats to their health as well as for their chances for reintegration into society.
Drug use is common among street children, posing serious threats to both their health and their chances for reintegration into society. It's difficult to reduce drug use among street children without a good understanding of the problem, and up to now the research has been confined mainly to local studies with inconsistent results.
Epilepsy, irregular heartbeats and other conditions caused by malfunctions in the body's nerve cells, also known as neurons, can be difficult to treat. The problem is that one medicine may help some patients but not others.
Drinking excessive amounts of cola and eating honey made from the pollen of Rhododendrons can cause unusual syncope (fainting) and symptoms of arrhythmia, report two case studies presented as abstracts at the EHRA EUROPACE 2013 meeting, in Athens 23 to 26 June.
The first European data on lead extraction was released today by the European Heart Rhythm Association (EHRA) of the European Society of Cardiology (ESC). The information is published in the EHRA White Book 20131, launched at EHRA EUROPACE 2013 in Athens, Greece, during 23-26 June.
Sorin Group, a global medical company and a leader in the treatment of cardiovascular diseases, announced today CE mark approval and the European commercial launch of the REPLY 200 family of pacemakers featuring Sleep Apnea Monitoring.
The heart's regular rhythm is crucial to the delivery of oxygenated blood and nutrients to all the organs of the body. It is regulated by a bundle of cells called "the pacemaker," which use electrical signals to set the pace of the heart. Dysfunction in this mechanism can lead to an irregular heartbeat, known as arrhythmia, and often necessitates the implantation of an artificial pacemaker.
Just a few years ago, integrated positron emission tomography and magnetic resonance (PET/MR) imaging was found only in research institutes, but little by little the technology has expanded into clinical practice.

Use of TYRX, Inc.'s AIGISRx- Antibacterial Envelope reduced major infection rates by more than 90% in patients undergoing Cardiovascular Implantable Electronic Device replacement procedures compared to similar high-risk cohorts, according to the CITADEL & CENTURION clinical study results presented on Saturday at the Late Breaking Clinical Trials session at Heart Rhythm 2013, the Heart Rhythm Society's 34th Annual Scientific Sessions.
A new Canadian study shows that operating without interrupting warfarin treatment at the time of cardiac device surgery is safe and markedly reduces the incidence of clinically significant hematomas compared to the current standard of care.
Aviir Inc., a biotechnology company dedicated to the prevention of cardiovascular disease through innovative laboratory tests, announced that it will be extending its offered services with comprehensive inherited cardiovascular disease genetic test menu.
Colorado Governor John W. Hickenlooper has proclaimed May to be Cardiac Arrhythmia Awareness Month (#RhythmAwareness), calling attention to the need for greater public awareness throughout the State about two serious heart rhythm disorders, atrial fibrillation (also known as AF or AFib) and sudden cardiac arrest (also known as SCA).
Inherited ventricular arrhythmias are an important cause of morbidity and sudden cardiac death in children who have structurally normal hearts. Despite conventional medical therapy, some of these children remain symptomatic with recurrent life-threatening arrhythmias, syncope, or frequent discharges from implantable cardioverter defibrillators.
BIOTRONIK, a leading manufacturer of cardiovascular medical technology, announced that the Food and Drug Administration granted approval for its Ilesto 7 implantable cardioverter-defibrillator/cardiac resynchronization therapy defibrillator series.
A new stress test protocol that investigates reducing the use of perfusion imaging in low risk patients undergoing SPECT myocardial perfusion imaging for possible angina symptoms was found to be diagnostically safe, revealed a US retrospective analysis.
