Abstract: Objective To analyze the electrocardiogram (ECG) characteristics of apical ballooning syndrome (ABS) in female patients in China. Methods 50 female cases of ABS patients from medical periodicals in China were analyzed. Results 50 patients were in sinus rhythm, 98% patients were abnormal in ECG. ST segment elevated in 85.7% of them, ranged 0.1-0.8 mV, and came down in 30 min-2 weeks. T wave inversion was found in 42% of them, 24% with pathological Q wave, which disappeared in 6 hours-1 month. 28% showed QT interval prolongated, 38% complicated with arrhythmia. Conclusion The abnormal ECG is common in female patients with ABS, which is transient and reversible.
