Abstract:
ObjectiveTo investigate the electrocardiogram (ECG) characteristics of patients with early repolarization variant (ERV).Methods One hundred and six patients diagnosed of ERV based on clinical and ECG and the healthy control group of 100 patients were analyzed and ECG features and ERV site were compared between these two groups.Results The mean heart rate( [ 68.6 ± 8.4 ] beats/min vs [ 74.8 ± 12.6 ]beats/min),QRS time( [95 ± 10] ms,[96 ± 11] ms vs[ 388 ± 12 ] ms,[379 ± 14]ms),QT dispersion and Tp-Te ( [ 80.4 ± 7.6 ] ms vs [ 78.5 ± 8.3 ] ms) were compared respectively between ERV group and control group and there was no significant difference (P ＞ 0.05).The occurrence of J wave in inferior leads was 67.9％,15.1％for the side wall leads,and 17.0％ for the chest leads,thus inferior wall leads had higher incidence than other hads relativelv in ERV ( P ＜ 0.01 ).Conclusion ERV exhibits more occurrence in inferior wall leads.
