emergency treatment
🚑 急 = urgent + 诊 = medical diagnosis, so 急诊 = emergency room visit
急 carries the sense of urgent or anxious; 诊 means to examine or diagnose a patient. Put them together and you get the urgent diagnosis you rush in for: emergency medical treatment.
急 — heart radical 心 + 及 (reach)
A semantic-phonetic compound: the heart radical 心 supplies the meaning (an emotional state) while 及 ('to reach, catch up') gives the sound. Originally it depicted a racing, anxious heart — hence the modern senses 'urgent,' 'hurried,' and 'impatient.'
