Abstract

|
E. K. G. was taken on fifty-four patients of diphtheria out of 140 who were admitted to Seoul National j
University Hospital during 1957-1958. The rest of the patients were not. checked on E. K. G. not because j
of the mildness of the disease but because of financial problem.
The E. K. G. was taken around on the 10th day of illness. Abnormal findings were seen on 20 i{ patients (37%).
The abnormal findings are as follows:
1) Rhythm 7 4) Prolongation of QT interval i 1
Sinus arrhythmia 5 5) Depression of S-T segment 2
Nodal rhythm 2 6) A-V Block 4
2) QRS axis deviation 13 Complete: 2
Left axis deviation 10 1st degree: 2
i, Right axis deviation 3 7) Bundle branch Block 5
i
3) Ventricular hypertrophy or Preponderance 2 Complete, right 3
Left 1 left I
Right 1 Incomplete 1
The prognosis of the diphtheria patients who showed A-V block or bundle branch block was poor. Both of the patient who had complete A-V block died and the two patients out of four who had complete bundle branch block died. e
The most severe complication in diphtheria is myocardial damage and this can be easily detected by the electrocardiographic changes which are usually seen between 5th and 12th day of the illness, and routine check on E. K. G. on the 7-10th day of the illness will be very helpful for the early detection and care for this severe complication.
