A constant association exists between abnormal surface electrocardiographic patterns characteristic of those seen in conventional electrocardiograms of subjects with coronary artery disease, and intracavitary evidence of premature depolarization. Local cavity “injury currents,” when sustained, are also associated with evidence of premature depolarization of an area of myocardium. The observations suggest that similar mechanisms of production may be attributable to abnormal electrocardiographic patterns in normal subjects as well as to the patterns obtained in disease states. It would appear that without regard to etiology, varying degrees of premature depolarization of an area of myocardium or of an entire ventricle and the time lapse between atrial and ventricular depolarization are capable of producing many different types of abnormal electrocardiographic patterns. |
