Abstract:
The present study was conducted on 20 adult albino rats divided into group I (n = 10) and group II (n = 10). Group I animals were exposed to cowdung smoke for 60 min twice a day for a period 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 degrees. Rats exposed to cowdung smoke revealed a significant increase in PR interval and a mean QRS of + 117.5 degrees. Our results indicate that inhalation of cowdung smoke leads to conduction defects and right axis deviation.
