sinus arrhythmia
1.The changes of electrocardiogram add up to 18 subtypes Sinus arrhythmia(30.5％),Primary S—T,T cha- nges(23.4％)and low QRS voltages ars common in these findinges.
2.The resting heart rate of the boxers is(48.24±9.06) beat/min,it is significantly lower than the controlling group(P<0.005),and there is equality in the incidence of sinus arrhythmia between the groups. These show that there is the enormous adaptogenesis of cardiac-vessel function in the boxers and these changes are the good performance of cardiac reserve and the symbol increased exercise capacity.
3.Among these cardiac arrhythmia,Ⅱ°Ⅱtype andⅢ°AVB accounted for 91.6%,sinus bradycardia and sinus arrest accounted for 8.4%.
4.Abstract In 95 patients (55 men and 40 women, aged 20 to 84 years) with sick sinus syndrome(SSS), 24-hour Holter monitoring (DCG) was performed. Four groups were classified according to the arrhythmia profiles.
5.We investigated the effect of CGRP on the arrhythmia induced by two drugs in rats, The result of our experiment has proved that CGRP could reduce the degrees of A-V block, resist the attack of sinus stanstill and ventricular fibrillation produced by ADP, and improve restoration of sinus rhythm.
