Catecholamine level in the blood, heart and adrenal tissues, and heart sensitivity to catecholamines were determined in 3-week-old rats after chemical sympathectomy. It was shown that tachycardia in sympathectomy rats was caused by increased heart sensitivity to catecholamines due to the reduction in their concentration.
