Abstract
This study presents the results of 43 direct current cardioversions performed in 38 patients between 1969–1970 at Ankara University. The primary aim was to evaluate the clinical success and investigate whether electrical shock affects serum enzyme (SGOT/SGPT) levels or causes myocardial damage. Results showed a success rate of 86% with sinus rhythm restoration; 30 cases required only one shock. Prospective enzyme assays in 19 patients showed no significant post-shock change in SGOT/SGPT, both in serum and coronary sinus blood. Potassium levels remained stable post-shock in most cases; minimal rises in some patients did not correlate consistently with post-conversion arrhythmias. The findings suggest that low-energy DC cardioversion does not induce notable myocardial injury or potassium shifts and is considered safe when contraindications are observed.

Abstract
Bu çalışmada 1969–1970 yılları arasında A.Ü. Tıp Fakültesi’nde 38 hastaya toplam 43 D/C kardiyoversiyon uygulanmış ve elde edilen sonuçlar sunulmuştur. Ameliyat dışı ritim düzenleme amacıyla yapılan şoklar neticesinde %86 başarı oranı ile sinüs ritmine dönüş sağlanmıştır; 30 vakada tek şok yeterli olmuştur. Prospektif olarak 19 hastada yapılan SGOT ve SGPT ölçümlerinde gerek serumda gerek koroner sinüs kanında anlamlı enzim değişikliği saptanmamıştır. Serum potasyum düzeyleri de çoğunlukla sabit kalmış; bazı vakalarda minimal yükselmeler ile postkardiyoversiyon aritmisi arasında tutarlı bir ilişki gözlenmemiştir. Bulgular, düşük enerjili D/C kardiyoversiyonun belirgin myokard hasarı veya potasyum kaybına yol açmadığını ve klinik olarak güvenli olduğunu ortaya koymaktadır.
