“…As mentioned previously, all but six patients exhibiting A T 7 dissociation were ophthalmic cases. T h e majority of these patients were children (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19) years of age, 77 YO), who were operated upon for strabismus. Organic heart disease was not clinically established in any of these children.…”

“…Some of these observations were made in the early days of its use when the limitations of this agent were not understood, and both depth of anaesthesia and carbon dioxide retention may have played a part (Faulconer and Bickford, 1960;Johnstone, 1951a). Similar arrhythmias have been experienced with all inhalation anaesthetics (Maher et at., 1934;Kurtz, Bennett and Shapiro, 1936;Johnstone, 1951b;Johnstone, 1955;Hunter, 1956;Cannard et ai., 1960;Johnstone and Nisbet, 1961). In this series the concentrations of trichloroethylene used were minimal, but, although aT-piece technique with an adequate gas flow was employed, one cannot rule out the possibility of respiratory depression against which the T -piece would not offer any protection.…”

Continuous electrocardiography was performed during eighty operations on the posterior fossa of the skull and fifty-seven other neurosurgical operations, all in the sitting position. There was little difference between the two groups in the incidence of arrhythmia before operation and during the surgical approach; more serious irregularities were almost entirely confined to periods when the surgeon was operating in the vicinity of the pons, the medulla, and the roots of the fifth, ninth and tenth cranial nerves. Severe arrhythmias may indicate or be the cause of medullary failure in this position and may also give an early warning of air embolism. Therefore continuous electrocardiography is valuable provided that its limitations are understood.

“…'5' 16,19,20 Such abnormalities (premature beats, tachycardia, displaced pacemakers) are usually trainsient and unaccompanied by clinical signs of embarrassment of the circulation. However, early recognition of significant arrhythmias and other electrocardiographic changes may forestall serious complications.…”

“…Similar arrhythmias have been noted by Kurtz and co-workers during noncardiac operations. 16 However, during pericardial resection, there was a definite relationship between the manipulation of the heart, traction on the pericardium as it was being dissected free, and the appearance of ventricular premature beats, singly, in pairs, or in runs (ventricular tachycardia).

The electrocardiographic behavior of the heart was observed in 100 patients undergoing heart operations. Most of the arrhythmias were unrelated to the cardiac operative procedure, but as in other thoracic procedures, were related to hypoxia, level of anesthesia, vagal reflexes, and changes in blood pressure. TA and S-T displacements occurred in all groups and were thought to be related to altered dynamics of the right auricle and ventricle. Prevention, recognition and control of disturbances of cardiac mechanism are discussed.T HERE are excellent observations"1-2' concerning cardiac mechanism during anesthesia and surgery but there are few10-'4 on the behavior of the heart during cardiac and cardiovascular surgery. The pressent report is a record of the behavior of the heart in four common types of surgical procedures: ligation or section of a patent ductus arteriosus,1 resection of the aorta in coarctation,2 increasing pulmonary artery blood flow in congenital cyanotic heart disease3' 4, and resection of pericardial scar in Pick's Disease. In all cases a medical cardiologist was present throughout the operation. The observer took frequent records and, in addition, watched the electrocardiogram. Changes in the electrocardiogram were correlated with direct observation of the heart,
