EKG is the American short form. It comes from German Elektrokardiogramm, which spells the heart part with K, so the letters are E-K-G. In British English the same test is an ECG, from electrocardiogram with a C. They are not two machines.

EKG is the American short formEKG是美式的簡稱。It comes from German Elektrokardiogramm它源自德文Elektrokardiogramm，which spells the heart part with K這個字裡「心」的部分是用K拼的，so the letters are E-K-G所以縮寫是E-K-G。In British English在英式英文裡 the same test同樣的檢查 is an ECG叫做ECG，from electrocardiogram with a C源自electrocardiogram，用C拼。They are not two machines它們不是兩種不同的機器。

Though actually, in Taiwan a patient almost always says the Chinese name, and hospital notes often write ECG; EKG sounds a bit American and textbook-medical if you say the letters aloud. You may also hear EKG used for the tracing itself, the printout, not only the act of doing the test.

Though actually不過其實，in Taiwan在台灣 a patient almost always says the Chinese name病人幾乎都直接說中文名稱，and hospital notes often write ECG而病歷上常寫ECG；EKG sounds a bit American and textbook-medical if you say the letters aloud如果你把字母唸出來，EKG聽起來會有點美式、有點教科書味。You may also hear EKG used你也可能聽到EKG被用來指 for the tracing itself, the printout那份記錄本身，也就是印出來的圖，not only the act of doing the test而不只是指做這項檢查的動作。
