Does the tingling pain on the underside of the left breast have anything to do with the heart?

If

there is no abnormal change in heart function and structure through ECG examination, imaging examination, etc., it is generally not considered to be related to the heart. However, for people with emotional overreaction, strenuous exercise, etc., it may lead to transient ischemia of the heart and feel tingling. In addition, for patients with myocarditis, rheumatic heart disease, coronary heart disease and other diseases, due to abnormal heart function and structure, it will also lead to tingling on the lower side of the left breast. If abnormal electrical activity and changes in heart structure are found through ECG and imaging examination, it is suggested that it is related to the heart.
