Abstract:
Objective To analyze the clinical significance of ECG changes in postures in the judgment of pathological atrioventricular block.Methods 62 patients with primary atrioventricular block were diagnosed by ECG examination.According to the complication,there were 31 cases with complication and 31 cases without complication.The two groups were taken sitting and squatting (1 min squat exercise,immediately lying position) ECG examination,the ECG abnormalities of the two groups were compared.Results In the comorbidity group,among the 31 patients,sitting electrocardiogram P-R interval returned to normal in 9 cases,abnormal in 22 cases,the normal rate was 29.0％ (9/31).Among the 22 cases of abnormal patients,squatting electrocardiogram P-R interval returned to normal in 1 case,abnormal in 21 cases,the normal rate was 4.5％ (1/22).Sitting,squatting electrocardiogram PR interval total returned to normal rate was 32.3％ (10/31).In the no complications group,among the 31 patients,sitting electrocardiogram PR interval returned to normal in 21 cases,abnormal in 10 cases,the normal rate was 67.7％ (21/31).Among the 10 cases of abnormal patients,squatting electrocardiogram P-R interval returned to normnal in 4 cases,abnormal in 6 cases,the normal rate was 40.0％ (4/10).Sitting,squatting electrocardiogran P-R interval total returned to normal rate was 80.7％ (25/31).Conclusion ECG changes in postures can early effectively determine the pathological and functional atrioventricular block.
