Explanation · 中文詳解

高血鉀(Hyperkalemia)對心臟具有極高的毒性。過高的血鉀會干擾心肌細胞的去極化與再極化過程,導致心電圖(ECG)出現特徵性變化,如 T 波尖聳(Tall, peaked T-waves)、QRS 波變寬,若未及時處理,極易演變成致命性的心室顫動(Ventricular fibrillation)或心跳停止。因此,對高血鉀病人的首要任務不是治療血鉀本身,而是先監測並穩定心臟功能。

Hyperkalemia poses a significant risk for life-threatening cardiac arrhythmias due to its effect on myocardial depolarization. Monitoring the electrocardiogram (ECG) is the priority to detect changes such as peaked T waves or widened QRS complexes early. This allows for immediate intervention to prevent ventricular fibrillation or cardiac arrest.
