目的探讨高血钾所致窦室传导的心电图表现及特征,及其与临床预后的关系。方法观察16例窦室传导患者的临床及心电图改变。结果 16例高血钾患者的临床及心电图均符合窦室传导,但其表现形式和演变特征不同,发现存在以下类型:①快速匀齐型;②缓慢匀齐型;③文氏或二度Ⅱ型阻滞型;④慢-快型;⑤不规则型;⑥类Brugada波样改变型。结论心电图诊断高血钾引起的窦室传导具备相对特异性,明确其类型,对患者病情变化的判定及治疗有一定临床意义。
Objective To investigate the electrocardiographic findings and characteristics of sinus hyperkalemia induced by hyperkalemia and its relationship with clinical prognosis. Methods The clinical and electrocardiographic changes of 16 patients with sinus conduction were observed. Results The clinical and electrocardiographic findings of 16 patients with hyperkalemia were all consistent with sinus conduction, but their manifestations and evolvement characteristics were different. The following types were found: ① rapid homogeneity type; ② slowly and homogeneously typed; ③ Venn or second degree Ⅱ Type retardation; ④ slow - fast; ⑤ irregular; ⑥ type Brugada wave-like change type. Conclusion ECG diagnosis of hyperkalemia sinus chamber conduction relative specificity, a clear type, the determination of the patient’s condition and treatment of some clinical significance.
