Abstract

A clinical study was made on 14 cases of coronary sinus rhythm and 17 cases of left atrial rhythm seen at the Kyungpook University Hospital during the past 13 years.

The incidence of coronary sinus rhythm among 23, 137 electrocardiograms was 0.07% and that of left atrial rhythm was 0.08%. Among the various types of left atrial rhythm as diagnosed by Mirowski's criteria, type III, posterior type and inferior type were far more common than others.

The most common underlying diseases were heart diseases in both coronary sinus rhythm and left atrial rhythm: five cases out of 14 in the former and 11 cases out of 17 in the latter were cardiac cases, respectively.
