CARDIOVASCULAR JOURNAL OF AFRICA • Volume 35, No 2, May – August 2024 78 AFRICA Anti-arrhythmic therapy was required in 10 patients due to paroxysmal supraventricular tachycardia. Even though Wolf–Parkinson–White syndrome is commonly associated with EA, none of our patients showed its electrocardiographic Survival curves for surgery type Based on Kaplan–Meier estimates Log-rank p – 0.094 Time (months) Number at risk Probability Surgery type = 1 19 19 19 18 17 14 10 9 8 4 2 Surgery type = 2 9 7 7 7 6 4 2 1 1 0 0 0 24 48 72 96 120 144 168 192 216 240 1.00 0.75 0.50 0.25 0.00 Fig. 3.
