Oxygen Administration upon Ventricular Tachycardia and Blood Pressure in Animals with Acute Myocardial Infarction

Abstract
The administration of oxygen, 60 to 70 per cent in inspired air, to dogs with ectopic ventricular tachycardia resulting from myocardial infarction produced no consistent changes in ectopic frequency, but the blood pressure was elevated during oxygen administration in every trial.
