The veins of TCM compound extracts are a folk prescription that has long been circulating in the northwest region of China. It has been clinically verified by the Urumqi Friendship Hospital, and it has some mitigation effects on common cardiovascular diseases such as hypertension, myocardial infarction and angina pectoris. This article focuses on its effect on the hemodynamics of anesthetized thoracic dogs. The LD_(50) obtained by intravenous injection was 3772.9 mg/kg according to the simplified probability unit method. The cardiac output (CO), left circumflex coronary artery (LcF), femoral artery flow (FAF), left intraventricular pressure peak (Lvppsp) heart were synchronously traced with a multi-channel physiological recorder.
