Bradycardia (slow heart rates) occurred more frequently than ventricular tachycardia (abnormal and dangerous rapid or chaotic heart rhythms): In the study, 19 of 50 patients had at least one bradycardia episode (with a rate of 26 bradycardia events per patient month); there were only two sustained ventricular arrhythmia episodes during the follow-up.
Most episodes are caused by a rapid and/or chaotic heart beat or ventricular fibrillation (the uncoordinated contraction of the cardiac muscle of the ventricles of the heart).
45am, medics gathered by her bed noticed a chaotic heart rhythm on a monitor and checked Savita's pulse.
Defibrillators deliver a potentially life-saving electric shock to the heart to stop the most common cause of SCA -- an electric malfunction that causes rapid and chaotic heart activity, called ventricular fibrillation -- and restore a normal heart rhythm.
The findings suggest that more than three-quarters of these patients -- specifically the roughly 675,000 people with moderate heart failure -- could potentially be at risk of sudden cardiac arrest (SCA) and could be protected by an ICD, which shocks the heart out of a rapid, chaotic heart rhythm that otherwise can lead to death within minutes.
Heart attacks can trigger a chaotic heart rhythm called ventricular fibrillation and lead to sudden cardiac arrest.
They were told the twins - and 41-year-old Mary Ann - suffered from Long QT Syndrome (LQTS), a rare abnormality of the heart's electrical system which brings on rapid, chaotic heart rhythms (arrhythmia) and can lead to sudden loss of consciousness and, sometimes, may cause sudden cardiac death.
SCA occurs when the lower chambers of the heart (the ventricles) suddenly stop beating normally and develop ventricular fibrillation (VF), a very fast, chaotic heart rate.
Other recommendations: -- Expand the number of patients eligible for implantable cardioverter-defibrillators (ICDs), devices implanted under the skin that save lives by shocking chaotic heart rhythms back into a healthy pattern.
Each year in the United States, more than 250,000 sudden cardiac deaths - or an abrupt loss of heart function such as a massive heart attack - are caused by the rapid or chaotic heart activity known as fibrillation, which is a type of arrhythmia, according to the American Heart Association.
The findings suggest that approximately 600,000 Americans with this heart condition could be at risk for sudden cardiac arrest (SCA) and should be protected by an ICD, which shocks the heart out of a rapid, chaotic heart rhythm that otherwise can lead to death within minutes.
