Özet
Previous studies of syndrome X (typical chest pain, positive treadmill exercise test, negative ergonovine test, negative hyperventilation test and angiographically normal coronary arteries) have suggested a potential etiologic role for excessive activation of the sympathetic nervous system. We evaluated the dispersions of Tapex-Tend(TT) and corrected TT as markers of sympathetic effects. Because TTd reflects inhomogeneity of the terminal part of ventricular repolarization. The present study we found TTd and TTcd increased in patients with syndrome X. We suggest these dispersions may be used to show chronic excessive sympathetic activation in patients with syndrome X or other diseases (LQTS etc) and predict the risk for arrhythmias and cardiac sudden death.
