The value of electrocardiography in patients with right ventricular endocardial pacemakers in the diagnosis of left ventricular hypertrophy: a correlative study of pace electrocardiography and left ventricular mass derived from M-mode echocardiography.
This study evaluated 51 patients with permanent apical right ventricular endocardial pacemakers. The assessment of the diagnostic value of pace electrocardiograms for the determination of left ventricular hypertrophy revealed specificity of 94% and sensitivity of 66%, applying a new parameter: RL1 + SV3 greater than or equal to 30 mm. The application of this criterion in the interpretation of pace electrocardiograms correlated well with values for the left ventricular mass derived from M-mode echocardiograms (r = 0.644, P less than 0.0001).
