Ekg:st意思

"EKG:ST" is not a standard medical term or acronym. It's possible that you're referring to an EKG (electrocardiogram), which is a test that measures the electrical activity of the heart, or ST segment, which is a portion of the heart's electrical cycle that is analyzed in EKG readings to assess cardiac health.

If you're referring to the ST segment, it's a part of the heart's electrical cycle that is visible on an EKG tracing and represents the period between the end of the QRS complex (which indicates the start of ventricular contractions) and the beginning of the T wave (which represents ventricular repolarization). Changes in the ST segment can indicate various heart conditions, such as myocardial infarction (heart attack) or other types of heart damage.

However, the "ST" in "EKG:ST" does not appear to be a standard usage, and it's more likely that you're referring to the ST segment specifically in the context of an EKG. If you have any concerns about your heart health or need clarification on a medical term, it's always best to consult with a healthcare professional.
