In this procedure, the small area in which the cells initiating JET are found can be destroyed by heating or freezing the tissue. This is accomplished using wires passed to the heart via the femoral vein through a small puncture in the groin. The main risk of this procedure is accidental damage to the AV node. This occurs more frequently when treating JET than other forms of supraventricular tachycardia, requiring treatment with a pacemaker in 5-10% of ablations for JET. The risk is lower if the tissue is frozen rather than heated.For those at risk of developing JET such as children undergoing heart surgery, treatment can also be given prophylactically. A meta-analysis of 9 studies found that sedation with dexmedetomidine reduced the risk of JET occurring post-operatively. Epidemiology
JET is most commonly seen in children following cardiac surgery. The arrhythmia affects 2-22% of children depending on the type of surgery performed, with higher rates seen following repair of Tetralogy of Fallot, and lower rates following the repair of ventricular septal defects and arterial switch operations. Etymology
Junctional ectopic tachycardia derives its name from the problem it causes. "Junctional" is used as the abnormal tissue driving the ventricular rate is located close junction between the atria and ventricles, known as the AV node. Ectopic (from the Greek ektopos, meaning "out of place") refers to the fact that the ventricles are being triggered by tissue that is not the normal pacemaker tissue within the heart.
Psychological
Various forms of group therapy or psychotherapy are often utilized to encourage and support abstinence from alcohol, or to reduce alcohol consumption to levels that are not associated with adverse outcomes. Mutual-aid group-counseling is an approach used to facilitate relapse prevention. Alcoholics Anonymous was one of the earliest organizations formed to provide mutual peer support and it is still the largest. Others include LifeRing Secular Recovery, SMART Recovery, Women for Sobriety, and Secular Organizations for Sobriety.Manualized Twelve Step Facilitation (TSF) interventions (i.e. therapy which encourages active, long-term Alcoholics Anonymous participation) for Alcohol Use Disorder lead to higher abstinence rates, compared to other clinical interventions and to wait-list control groups. Moderate drinking
Rationing and moderation programs such as Moderation Management and DrinkWise do not mandate complete abstinence. While most people with alcohol use disorders are unable to limit their drinking in this way, some return to moderate drinking. A 2002 US study by the National Institute on Alcohol Abuse and Alcoholism (NIAAA) showed that 17.7% of individuals diagnosed as alcohol dependent more than one year prior returned to low-risk drinking. This group, however, showed fewer initial symptoms of dependency.A follow-up study, using the same subjects that were judged to be in remission in 2001–2002, examined the rates of return to problem drinking in 2004–2005. The study found abstinence from alcohol was the most stable form of remission for recovering alcoholics.
