Comprehensive NIH study helps explain discrepancy in survival rates between cardiac arrests in public and at home Cardiac arrests that can be treated by electric stimulation, also known as shockable arrests, were found at a higher frequency in public settings than in the home, according to a National Institutes of Health-funded study appearing in the Jan. 27 issue of the New England Journal of Medicine. The study compared home and public cardiac arrests under various scenarios. For example,...

(Ivanhoe Newswire) -- A new study shows the frequency of a potentially deadly heart rhythm is lower among patients who suffer cardiac arrests at home than among those who have them in a public setting. In order to find out if there was a link between the location of the cardiac arrest, the type of irregular heartbeat, and the probability of survival, Myron L. Weisfeldt, M.D., William Osler Professor of Medicine and Director of the Department of Medicine at the Johns Hopkins University School...

People who drink alcohol on a regular basis, especially those who are considered heavy drinkers, might be more likely to suffer the common heart-rhythm disturbance atrial fibrillation (AF) than those who abstain from intoxicating drinks, according to suggestions from a new research review. Based on the analysis of 14 separate studies, researchers found that the heaviest drinkers were more likely to be diagnosed with AF than those who drank little to no alcohol. The studies differed in what...

While automated external defibrillators improve survival for out-of-hospital cardiac arrest, an analysis of data indicates their use for cardiac arrest in a hospital does not result in an improved rate of survival, according to a study in the November 17 issue of JAMA. The study is being released early online because it will be presented at the American Heart Association's annual meeting. Use of automated external defibrillators (AEDs) has been proposed as a strategy to reduce times to...

Understanding sudden cardiac death in dialysis patients will aid in developing better standards for prevention Approximately 500,000 Americans require dialysis to treat kidney disease; of that population nearly half of the deaths that occur are caused by cardiovascular disease. Dialysis patients are at elevated risk for sudden cardiac death, but physicians are unclear why these deaths occur because little research has been done to examine how to best manage heart disease in this high-risk...

The earlier that patients who suffer from atrial fibrillation obtain the correct treatment, the lower is the risk of serious secondary effects such as stroke. A thesis presented at the University of Gothenburg, Sweden, shows that a well-established measurement score can easily assess the risks for this patient group. The function of the heart is affected if it is subject to atrial fibrillation for a long period. It becomes successively more difficult to restore and maintain the normal heart...

Chaos models may someday help model cardiac arrhythmias -- abnormal electrical rhythms of the heart, say researchers in the journal CHAOS, which is published by the American Institute of Physics. In recent years, medical research has drawn more attention to chaos in cardiac dynamics. Although chaos marks the disorder of a dynamical system, locating the origin of chaos and watching it develop might allow researchers to predict, and maybe even counteract, certain outcomes. An important example...

ST. LOUIS, May 4 /PRNewswire-FirstCall/ -- Stereotaxis, Inc. (Nasdaq: STXS) today updates progress on a global multi-center clinical study on ventricular tachycardia treatment outcomes by using the company's proprietary Niobe® Magnetic Navigation System. Ventricular tachycardia (VT) is a life-threatening arrhythmia because it may lead to ventricular fibrillation, asystole, and sudden death. VT is one of the most challenging arrhythmias facing electrophysiologists due to...

MINNEAPOLIS, March 18 /PRNewswire/ -- Today the Minnesota State High School League and Take Heart(TM) Minnesota together with the Medtronic Foundation announced they are "teaming up" to save more lives from sudden cardiac arrest (SCA). Their statewide effort "tips off" tonight with CPR training for more than 50 students on the court during halftime, performed to the song "Stayin' Alive" played by the Lakeville South High School band. SCA is a leading cause of death in young athletes....

Newly identified gene may open route to innovative treatments for atrial fibrillation Atrial fibrillation is a cardiac arrhythmia "“ a chronic irregularity of heartbeat "“ which affects an estimated 1 million people in Germany. Although the condition is not acutely life-threatening, it does increase the risk of developing more serious illnesses, such as cardiac insufficiency, stroke and dementia. In the third of a series of genomewide association studies, an international team of...

Precordial Thump
2012-12-31 12:53:08

The precordial thump is an application of mechanical energy through a calculated strike to the torso when in a specific fatal heart rhythm. This procedure is used in very specific circumstances by highly trained health professionals with ACLS certifications. The Procedure While in the presence of a patient that is suffering a potentially fatal heart rhythm, a medical provider can strike a calculated point on the sternum to disrupt that rhythm. The energy transferred by the provider is...
