ECG feature

An ECG feature refers to the specific patterns and characteristics in the electrical signals of the heart recorded during an electrocardiogram test. These features include waves, intervals, and segments that reflect the heart's electrical activity, such as heartbeat timing, rhythm, and strength. Doctors analyze these features to detect abnormal heart rhythms, ischemia, or other cardiac issues. Essentially, ECG features help provide a snapshot of how well the heart's electrical system is functioning, offering valuable insight into overall cardiac health.
