The study was focused on heart rate(HR) variation of sinus rhythm before 5 minutes attacking, relationship between premature atrial contraction, coupling interval and PAF episodes.
结论老年收缩期高血压左室肥厚与心衰密切相关，积极改善左心室重塑有助于延缓心衰的发生。
Conclusion Senile systolic hypertension left ventricular hypertrophy is closely related to heart failure, it is helpful to delay the occurrence of heart failure to improve left ventricular remodel.
结果表明，应用波生坦后，尽管收缩期和舒张期血压没有变化，收缩末期和舒张期心室体积比例明显升高。
Peak systolic and diastolic strain rates also increased significantly after bosentan treatment, the results indicate, although systolic and diastolic blood pressures were not affected.
