A new ECG sign for sudden death: Transient prolonged QT interval following premature contraction / 中南大学学报(医学版)

Early recognition and treatment for early warning electrocardiogram (ECG) of sudden death are very important to prevent and treat malignant arrhythmia and sudden death. Previous studies have found that R-on-T and T wave alternation, and QT interval prolongation are closely related to malignant arrhythmia or sudden death, which are included in the critical value of ECG.By analyzing the ECG characteristics of 4 patients with sudden death, we found that although the causes of the patients were different, there were transient prolongation of QT interval after premature contraction in 12 lead ECG, followed by malignant arrhythmia or sudden death. Thus, we thought that the transient prolongation of QT interval after premature contraction had a high value for warning malignant arrhythmia or sudden death. This phenomenon should be paid enough attention to reduce the risk of sudden death.

"Probe into the preliminary application of micro-Seminar in ""Pediatric Nursing"" teaching" / 中国实用护理杂志

Objective To reform the traditional teaching methods,and to explore the feasibility and effect of micro-seminar applied in Pediatric Nursing teaching.Methods A total of 151 undergraduate students of nursing admitted in the year of 2011 were selected as the experimental group,using micro-Seminar teaching method,while 152 undergraduate students of nursing admitted in the year of 2010 as historical control (the traditional teaching group).The application effect of micro-Seminar in Pediatric Nursing teaching was investigated and evaluated.Results Students of micro-seminar group got higher score in the final examination than students of the traditional teaching group [(81.34 ± 8.34) vs.(78.40 ± 8.03)],and the difference was statistically significant (P＜0.05).Micro-seminar was accepted by 92.7％ of students of the experimental group as a new teaching method,and students unanimously affirmed it was beneficial to enhancing their individual abilities of learning,cooperation,communication,and expression.Conclusions Micro-seminar pedagogy could help cultivating students' comprehensive abilities and improving teaching effect and quality.As was high operability,micro-Seminar was worth applying and popularizing.
