Diagnosing abnormal heart rhythm with web camera

Atrial fibrillation (AF) is one of the commonest abnormal heart rhythms. In AF, the normal regular electrical impulses generated by heart's native pacemaker (SA node) are overwhelmed by disorganized electrical impulses from elsewhere. As a result of irregular conduction of impulses, the atria (upper heart chambers) and ventricles (lower heart chambers) beat out of sync. This abnormal rhythm is associated with a variety of medical conditions. The incidence and prevalence of atrial fibrillation...

Excessive TV watching can lead to stiffening of major vessels

  Studies done in the past have found an association between increased time spent in front of TV and higher likelihood of developing conditions like obesity, diabetes, cholesterol and blood pressure. But in a first study of its kind, researchers from Netherlands have found that watching excessive television can also lead to stiffening of major arteries. The study has been published in the recent issue of the British Journal of Sports Medicine. For their research, the researchers concentrated...

Blood pressure cuff may be life-saving in acute heart attack

mi bp cuff
A new study published in the latest issue of the European Heart Journal has found that using a blood pressure cuff in patients being transported to hospital for treatment of acute heart attack can prove life-saving. The research was carried out by researchers from Aarhus University Hospital and Aarhus University.   The researchers followed up 251 patients between the period of February 2007 and November 2008 who had suffered ST elevation myocardial infarction and were taken to hospital...

Hypoglycemia can lead to a damaged heart

hypoglycemia damages heart
According to the results obtained from a new meta-analysis published online in the British Medical Journal, low sugar levels in the blood can damage the heart. The research was carried out by Mitsuhiko Noda from the National Center for Global Health and Medicine in Tokyo, along with his colleagues. For their study, the researchers analyzed the results of six cohort studies. This included 903, 510 individuals suffering from diabetes type 2. The researchers tried to find an association between...

Biventricular pacing found to be better in atrioventricular block

cardiac pacing
  A study published in the latest issue of the New England Journal of Medicine has found that in patients suffering from atrioventricular block with depressed left ventricular ejection fraction, biventricular pacing gives better results compared to the standard right ventricular pacing. The study was led by Anne Curtis from the University of Buffalo, New York, along with her colleagues.   The study was undertaken as it was seen that the conventional right ventricular pacing in patients...
