An electroencephalographic investigation of short-term effects of three hypothalamic hormones (TRH, LH/FSH-RH, GH-RIH) in normal subjects.

abstract：AIMS:QTc interval-prolonging drugs have been linked to cardiac arrhythmias, cardiac arrest and sudden death. In this study we aimed to quantify the risk of cardiac arrest associated with the use of non-antiarrhythmic QTc-prolonging drugs in an academic hospital setting. METHODS:We performed a case-control study in whi...
