According to American Heart Association/American College of Cardiology Practice Guidelines, electrolyte abnormalities, including abnormal serum @entity972 concentrations, are considered a correctable cause of a life-threatening @entity943 . @entity67 therapy in this situation is a class III indication, and thought to be ineffective and perhaps harmful, although there are minimal data to support this recommendation. The steady-state serum @entity972 concentration frequently changes during a @entity1167 . Additionally, the vast majority of @entity1167 @entity1 have structural @entity299 and are commonly treated with a variety of medications that can alter the serum @entity972 concentration. In the Antiarrhythmics Versus Implantable Defibrillators (AVID) trial, @entity1 with a correctable cause of an electrolyte imbalance were excluded from study participation but were followed in the AVID registry. Similar outcomes were observed among @entity1 in the AVID registry and the main trial. @entity1482 therapy in @entity1 with @entity712 decreases all-cause mortality and sudden and nonsudden @entity204 . In a preliminary study of 169 @entity1 with an episode of a sustained @entity943 treated with an implantable defibrillator, freedom from appropriate defibrillator therapy was 18% after five years. The probability of appropriate defibrillator therapy was independent of the initial serum @entity972 concentration. For these reasons, our current clinical practice is to use an implantable defibrillator to treat an initial episode of sustained @entity1165 or @entity2224 that occurs in a @entity1 with structural @entity299 and an abnormal serum @entity972 concentration.

Should an abnormal serum @entity972 concentration be considered a correctable cause of XXXX ?
