Abstract

A patient with severe hypertension, hypokalemia and marked T-U wave alternans on electrocardiogram is reported for its rarity. Relevant literature is reviewed. Recent data indicate that electric alternans is related to changes in action potential configuration, and that it may be a marker of cardiac electrical instability.

摘要

本文报告了一例患有严重高血压、低钾血症且心电图上有明显T-U波交替现象的患者，因其罕见性。对相关文献进行了综述。近期数据表明，电交替与动作电位构型的变化有关，并且它可能是心脏电不稳定的一个标志。
