Abstract

Detection of high intensity transient signals (HITS) in the carotid artery was performed as a screening for 463 employees of a general company (mean age 47.2 years). HITS was detected in the common carotid artery for 5 minutes with a paste type ultrasonic probe taped to the neck. As a result, it was detected in 17 out of 463 (3.7%), 4 out of 126 under 40 years old (3.2%), and 13 out of 337 over 40 years old (3.9%). Of the 17 patients with carotid HITS detected, 1 had valvular heart disease, 2 had arrhythmias, and 2 had atrial fibrillation, including paroxysmal atrial fibrillation. In addition, the background factors of carotid artery HITS were not significantly different in age, gender, blood pressure, diabetes, hypertension, lipid abnormalities, etc., but were significantly different in heart disease, arrhythmia, and atrial fibrillation including paroxysmal. Therefore, most carotid HITS in general company examination were considered to be due to arrhythmia such as atrial fibrillation.
