From German EKG. Initialism of German Elektrokardiogramm.
In the US, this spelling is more common than (and may even be preferred over) the ECG spelling, particularly in medical contexts where both electrocardiograms and electroencephalograms may be present. This is mainly due to the ease with which ECG (ee-cee-gee) may be confused with EEG (ee-ee-gee) in most American English dialects.
