“…The frequency of arrhythmias and complete RBBB was rather high in the present material as compared to findings in materials consisting of younger patients [1,22,24]. It is, however, in fairly good agreement with other reports [6,20,21,27,28,32,33] on adult patients, supporting the concept that the frequency of these abnormalities increases with age [7,28].…”

Surgery for atrial septal defect of the secundum type was performed in 84 patients over 40 years of age. Electrocardiograms were studied preoperatively and at a follow-up visit 74 months (range 22–174 months) after surgery. Preoperatively, atrial fibrillation was observed in 13% of the patients, complete right bundle branch block in 30%, and a secondary R wave (R’) in lead V₁ in 72%. A significant correlation was found between the amplitudes of S V₆ and R’V₁ and the right ventricular systolic pressure, whereas no significant correlation could be demonstrated between the shunt ratio and any of the QRS parameters. After successful surgery, the mean QRS axis in the frontal plane shifted from +99° to +47° (p < 0.01), and the following highly significant (p < 0.001) changes were noticed: increase of the amplitude of S V_1’ shortening of the QRS duration in V_1’ increase of the ratio QR’/QRS V_1’, shortening of the duration of S V_6’ and diminution of the initial forces of the P wave in V₁.

“…Specifically, Pryor, Woodwark, and Blount (1959) and Burchell, DuShane, and Brandenburg (1960) found that most defects of the ostium primum type were associated with left axis deviation, while normal or rightward QRS forces in the frontal plane were the rule with secundum defects. Only rarely has such deviation been recorded with ostium secundum lesions (Harrison and Morrow, 1963).…”

“…Ref. 18). The causes for this discrepancy are under standable in view of the emphasis placed on terminal slurrings; the use of high fidelity (oscilloscopic) recordings, and the advan tage of the spatial approach over the simple inspection of scalar leads.…”
