ABSTRACT
Objective To investigate the characteristics and clinical value of dynamic electrocardiogram in the treatment of patients with congestive heart failure and atrial arrhythmia.Methods A total of 226 congestive heart failure patients were taken into this research.124 congestive heart failure and atrial arrhythmia patients were divided into OSG group,102 congestive heart failure patients were divided into CTG group.24 -hour Holter monitoring was examined in both groups with ATA including AFR,AFL,ATC and PAC by dynamic electrocardiogram made in Mei Gaoyi medical equipment company.Results The ATA was (824.6 ±108.2)times(compared with the control group, t =9.054,P =0.019)in 124cases of the OSG group,including ATC (80.4 ±25.8)cases (compared with the control group,P =0.021,t =8.934).duration time (25.4 ±9.7)s,AFL (26.8 ±7.1 )cases(compared with the control group,P =0.014,t =9.162).duration time (13.5 ±5.8)s,AFR (97.5 ±51.3)times (compared with the control group,t =9.314,P =0.009).duration time (70.1 ±18.5)s,PAC (41.9 ±14.3)cases (compared with the control group,t =8.796,P =0.026).duration time (34.8 ±11.2)s.The ATA was (102.6 ±59.3)times in 102cases of the CTG group,including ATC (69.5 ±19.4)cases,duration time(5.7 ±1.3)s,AFL(8.5 ±2.6)cases,duration time (2.6 ±0.9)s,AFR (27.6 ±12.5)times,duration time,PAC(24.8 ±10.4)cases,duration time(19.6 ±7.9)s, which was significantly different with the CTG group(t =8.796,P <0.05).Conclusion CHF patients are probable to be complicated with ATA.The DCG examination in CHF patients is conducive to improve the effect of treatment and limit chances of sudden death,which is worthy of promotion.
ABSTRACT
Objective To investigate the causes of bicycle injuries among middle school students in rural areas and attitudes of students, their parents and teachers toward bicycle injuries.Methods 103 respondents in 14 groups were interviewed using focus group discussion outline. Data were taped and interpreted by two experienced researchers using the QSR NVivo 8.0 software.Results Disobeying the traffic rules, riding bicycle carelessly and fast speed when riding bicycle were the first leading causes of bicycle injuries among middle school students. The relative importance of disobeying traffic rules, inattentive riding the bicycles and fast speed were 1.00, 0.80 and 0.78respectively. Students, their parents and teachers held different attitudes toward the determinants of road condition(23 person-time)'. Fast riding speed was the most important subjective cause (students and parents were 14 and 8 person-time during the interview)but teachers thought that disobeying traffic rules was the most important one(by 14 person-time). Conclusion Residents in rural China had low awareness of child bicycle injuries. There is a need to improve the awareness of road safety among rural residents. Future intervention strategies should be tailored to address main determinants to reduce the incidence of road traffic injuries among children.
