OBJECTIVEThis thesis will discuss the value of RV(6) > RV(5) of ECG in diagnosis of pneumocardiac disease complicated by left ventricular hypertrophy in coal-workers with pneumoconiosis through the analysis of the ECG characteristics in the postmortem examination of coal-workers with pneumoconiosis.

METHODSThree data groups will be formed on the basis of the ECG data in the case 47 postmortem examination of coal-workers with pneumocardiac disease complicated by left ventricular hypertrophy, and they are right deviation group with ECG cardiac electric axis more than 90 degrees (case 16), no deviation group with ECG cardiac electric axis between 30 degrees and 90 degrees (case 16) and left deviation group with ECG cardiac electric axis between 30 degrees and -30 degrees (case 15). The method that this thesis adopted is to compare the thickness of the right and left ventricle walls of the three groups, their ratio and the detectable ratio of ECG RV(6) > RV(5).

RESULTSThe detectable rate of the thickness of right ventricle front wall, the thickness of the left ventricle wall, the thickness of the left ventricle wall to the thickness of right ventricle wall and ECG RV(6) > RV(5) in left deviation group is obviously higher than those of the no deviation group and right deviation group. The differences between the three groups are of statistics significance (P < 0.01); the detectable rate of the thickness of right ventricle front wall, the thickness of the left ventricle wall, the thickness of the left ventricle wall to the thickness of right ventricle wall and ECG RV(6) > RV(5) in no deviation group is obviously higher than those of the right deviation group. The differences are of statistics significance (P < 0.01). In case 47 that pneumocardiac disease complicated by left ventricular hypertrophy in coal-workers with pneumoconiosis, the ECG shows 20 cases of ECG RV(6) > RV(5). There are altogether 3 kinds of ECG types: (1) 14 cases of ECG RV(6) > RV(5); (2) 4 cases of left ventricular hypertrophy; (3) 2 cases of right ventricular hypertrophy.

CONCLUSIONSThe left deviation of ECG cardiac electric axis and ECG RV(6) > RV(5) can be used as indications to diagnosis of pneumocardiac disease complicated by left ventricular hypertrophy in coal-workers with pneumoconiosis.

PURPOSE: The purpose of this study was to determine the effects of foot reflexology on fatigue and insomnia in patients suffering from coal workers' pneumoconiosis. METHOD: This study was a quasi-experimental study of pre-test and post-test design in a non-equivalent control group. The subjects of this study consisted of both the experimental group of twenty-nine and the control group of thirty coal workers' pneumoconiosis patients. Data was collected from December 10, 2002 to February 15, 2003. Foot reflexology was performed for 60 minutes twice a week through five weeks in the experimental group, but none in the control group. To evaluate the effects of foot reflexology, the scores of fatigue and insomnia were measured before and after the experiment in both groups. Fatigue was evaluated by Fatigue Symptoms Inventory. Insomnia was measured with the visual analogue scale (VAS). Data of this experiment was analyzed by Chi-square test, t-test, unpaired t-test and Repeated Measures ANOVA with the SAS Program. RESULTS: The scores of fatigue and insomnia decreased in the experimental group but not in the control group. There was a significant difference of fatigue and insomnia between the two groups. CONCLUSION: It is suggested that foot reflexology might have beneficial effects on reducing fatigue and insomnia in patients suffering from coal workers' pneumoconiosis, and can be recommended as a nursing intervention program for patients with coal workers' pneumoconiosis.
