[Clinical valuation color Doppler echocardiography for diagnosis of coronary artery fistula].
The purpose of this study was to investigate the advantages of color Doppler echocardiography in the diagnosis of congenital coronary artery fistula. Twenty-one patients with coronary artery fistula ranging in age from 3 to 28 years underwent color Doppler echocardiographic study 1991.4-1996.8. ⋯ The results indicate that color Doppler echocardiography can provide a panoramic view of coronary artery and the fistulous vessel with precise definition of the origin, the course of draingae site of the fistula. Therefore, it is the noninvasive method of first choice to diagnose congenital coronary artery fistula.

[The study of acute clinical electrophysiological effects of propafenone on paroxysmal supraventricular tachycardia using transesophageal atrial pacing technique].
Trans-esophagus atrial pacing (TEAP) was employed to evaluate the acute electrophysiological effects of propafenone administrated intravenously in 50 patients with SVT. Forty three of the subjects are patients with atrial ventricular reciprocating tachycardia (AVRT). Seven of them were involved in atrioventricular nodal reentry tachycardia (AVNRT). ⋯ All these promise the potential terminating effect on tachycardia. Propafenone has little effects on sinus node. Prolongation of sinus node recovery time (SNRT) to 3600 ms following drug administration was observed in only one patient who has a history of sinus bradycardia.

[Correlation between shape and direction of small articular surface in lower lumbar vertebrae and degeneration of intervertebral disc].
To assess the possible correlation between the shape and the direction of the small articular surface in the lower lumbar vertebrae and the degeneration of the intervertebral disc, we investigated with computed tomography (CT) and evaluated with statistics the small articular surface and the transverse interface-joint angle (TIFA) of the L4-5 and the L5-S1 in 152 cases who had normal or degenerative discs verified through CT, MRI or operation. The small articular surface was found arc in 69.1% of the L4-5 and in 23.0% of the L5-S1. ⋯ There was no correlation between the ratio of degeneration of the intervertebral disc at the L4-5 and the TIFA of the L4-5 and the L5-S1, but the ratio of degeneration of the intervertebral disc at the L5-S1 had postive correlation with the TIFA of the L4-5, negative correlation with the TIFA of the L5-S1, and particular correlation with the TIFA of the L5-S1 and L4-5. These results suggest that the shape and direction of the lower lumbar facet joint are related to the lumbar degeneration of intervertebral disc and the causes of degeneration at the L4-5 disc differ from those at the L5-S1 disc in biomechanics.

The clinical characteristics of 120 patients with fibromyalgia is reported. Most of the patients were 21-50 years old. ⋯ The trigger point was regarded as an important physical sign. The etiology and differential diagnosis for fibromyalgia were discussed.

Comparative Study[Comparison between intraarterial pulsegraphy and thermodilution method for determination of cardiac output during anesthesia and operation in patients undergoing cardiac valve replacement].
Comparison of intraarterial pulsegraphy and standard thermodilution methods for determination of cardiac output (CO) in 14 patients with poor cardiac function following valve replacement operation was performed. The CO, cardiac index (CI) were moderate to high correlated between the two methods before and after valve replacement respectively. The study indicates that intraarterial pulsegraphy provides a continous method of determining CO in patients with poor cardiac function during operation.
