Why the study?
What are the normal electrocardiogram and blood pressure changes during surgical operation and convalescence in nondigitalized patients?
What are the normal electrocardiogram and blood pressure changes during surgical operation and convalescence in nondigitalized patients?
This study establishes baseline electrocardiogram and blood pressure changes during surgery in nondigitalized patients to serve as a control for evaluating preoperative digitalis.

Provides historical perioperative ECG/BP reference data; leaves open digitalis effects in current surgical populations.
It is apparently the belief of many surgeons and internists that post-operative complications may be lessened or prevented by the preoperative administration of digitalis, even to patients whose hearts are apparently normal. 1 The present investigation was undertaken in an attempt to determine the influence of digitalis on certain objective factors during and after surgical operation, but, as no similar study has been found in previous reports, it seemed necessary to establish first a control group of nondigitalized patients for subsequent comparison with a similar group of patients who had received digitalis. It is the nondigitalized group which forms the basis for the present report; the influence of digitalis is discussed in the following paper. METHOD OF STUDY It has been our purpose to secure records of the blood pressure and electrocardiograms at frequent intervals during the induction of anesthesia and operation, and records of the blood pressure and electrocardiograms at
