Correlative effects of quinidine on ECG pattern and serum cholesterol concentration in Acridotheres tristis.
Antiarrhythmic drug quinidine, administered daily at the rate of 10 mg/kg for 7 days in A. tristis produced an increasing effect on the amplitude and duration of different waves and intervals. Heart rate was decreased from 478.40 to 444.47 beats/min. Serum cholesterol level was reduced from 86 to 54.30 mg/100 ml. The data of the effect of quinidine on the ECG pattern and serum cholesterol were analysed and the values of the correlation coefficient and their significance were computed. The values of the correlation coefficient computed between the level of serum cholesterol (Y) and P-R interval (X) comes out to be significant at 5% level of significance. A linear regression line Y on X was fitted to the above data and the line is found to be: Y = 2535.897 X -62.858. This regression line may be used to determine the level of serum cholesterol on the basis of changes in the P-R interval of the ECG tracing in the quinidine treated birds.
