Firstly, there is no direct connection between coronary heart disease and premature contractions. If we must discuss whether ventricular premature beats are related to coronary heart disease, we should mainly consider patients with myocardial ischemia, especially those with active myocardial ischemia. In these cases, premature beats may be somewhat related to coronary heart disease, but these two conditions cannot be directly equated. Since the majority of premature contractions are unrelated to coronary heart disease, these two issues should not be confused or directly equated.

It is common to see some elderly people with premature contractions on their ECGs and consider coronary heart disease, but this consideration is not entirely correct. Of course, the occurrence of real premature beats, especially frequent ventricular premature beats, also suggests the possibility of myocardial ischemia. However, a large number of people, even those with obvious real premature beats, do not have significant coronary insufficiency, thus there is no direct relationship between the two.
