چکیده
The present study was conducted on 20 adult albino rats divided into group I (n=10) and group II (n=1 0). Group I animals were: exp sed to cowdung smuke fOr 60 min twice a doy for a pf.'riod of 75 days whereas group II served as control. ECG of control rats was essentially similar to that of man. ST segment was absent, Q wave absent or rudimentary and the mean QRS axis + 45". Rats exposed to cowdung smoke reveafed a significant increase in PR interval and a mean QRS of + 117 5°. Our reSUlts indicate that inhalation of cowdung smoke leads to conduction defects and right axis deviation.
