低钾型周期性麻痹患者血钾浓度与肌力、心电图改变及肌酶水平的关系探讨

目的 探讨低钾性周期性麻痹(HOPP)患者血钾浓度与肌力、心电图及肌酶的关系.方法对80例HOPP患者进行血钾浓度、肌力、心电图及肌酶水平检测并分析.结果 80例HOPP患者中,轻度低钾组20例,中度低钾组34例,重度低钾组26例,3组中血钾浓度与肌力关系不恒定(P＞0.05).80例HOPP患者中心电图异常68例,占...

Association of plasma potassium concentration with muscle tone, ECG, and levels of serum muscle enzymes in patients with hypokalemic periodic paralysis

Objective To explore the association of plasma potassium concentration with muscle tone, ECG, and levels of serum muscle enzymes in patients with hypokalemic periodic paralysis.Methods The muscle tone, ECG, levels of serum muscle enzymes, and plasma potassium concentration wore measured and then analyzed in 80 patients. Results Of 80 patients, 20 patients had mild hypokalemia, 34 had moderate hypokalemia, and 26 had severe hypokalemia. The relation between muscle tone and potassium was not stable ( P＞ 0.05 ). 68 patients ( 85% ) developed abnormal ECG changes; the occurrence of abnormal ECG increased with the decrease in potassium levels. 64 patients( 80% ) had an elevated levels of muscle enzymes; and the levels of muscle enzymes were negatively related with potassium concentration. Conclusions Understanding of the association of plasma potassium concentration with with muscle tone, ECG, and levels of serum muscle enzymes is very important in the diagnosis and treatment of hypokalemic periodic paralysis.
