Abstract:
Objective To explore the effects of premature atrial contractions on hemodynamics combined with coronary heart disease and hypertension .Methods According to the advance rate ,62 patients with premature atrial contractions were invided into 3 groups :< 20% group(n= 18) ,20% - 40% group(n= 20) and > 40% group(n= 24) .All of the patients were performed imped‐ance cardiography .The hemodynamics indexes at different times were compared ,and the variation rates in hemodynamics of the three groups combined with basic diseases were analyzed .Results Stroke volume(SV) ,stroke index(SI) ,aortic compliance(AC) , stroke work(SW) ,stroke work index(SWI) ,and heather index(HI) were smallest when premature atrial contractions ,which were middle when the first sinus beats before premature atrial contractions ,and largest when the first sinus beats after premature atrial contractions(P< 0 .05) .The variation rates in hemodynamics were smallest in < 20% group ,which were middle in 20% - 40%group ,and largest in > 40% group(P< 0 .05) .The percentage of patients with basic heart diseases was lowest in < 20% group , which was middle in 20% - 40% group ,and highest in > 40% group(P< 0 .05) .Conclusion The advance rate is relatively large in patients with basic cardiovascular disease .Premature atrial contractions has certain effects on hemodynamics ,and the effects are positively correlated with advance rate .
