Clinical observations with the Frank precordial lead system.
Several new lead systems for electrocardiography and vectoreardiography have been proposed. Clinical evaluation of these systems is necessary to determine whether they yield useful information in addition to that furnished by conventional leads and whether the same information obtained from conventional leads appears in recognizable form in the new leads. This study is a step toward such an eva...
متن کاملClinical observations with an orthogonal lead system.
TI IE MERITS of several orthogonal lead systems are being investigated and it is possible that records from one or more of the systems will be incorporated into clinical electrocardiography. Selection of a system for clinical use involves consideration of its accuracy, convenience, and reproducibility of the results it yields. An electrode arrangement termed the "axial" system has recently been...
متن کاملPrecordial Lead Patterns in Right Ventricular Hypertension.
CURRENT criteria for the electrocardiographic diagnosis of right ventricular hypertrophy -3 depend primarily upon abnormal axis deviation and changes in the right precordial leads (V1, V4.R7). The R/S ratio in these leads has proved to be of great value in the recognition of right ventricular hypertrophy. Various patterns (qR, rS, rsR', Rs) are encountered and many theories have been put forwar...
