Baseline Electrocardiographic Abnormalities in Pre-Treatment Cancer Compared With Non-Cancer Patients: A Propensity Score Analysis
Table
| Characteristics | Controls n = 267, (%) | Cases n = 228, (%) | P value | ORa (95% CI) |
|---|---|---|---|---|
| aAfter propensity score matching for CAD, hypertension, and Hispanic or Latino ethnicity. bBased on summed ECG score with each abnormality tallied as 1 point. cIncludes tachycardic, bradycardic and irregular rhythm. CI: confidence interval; ECG: electrocardiogram; LBBB: left bundle branch block; LVH: left ventricle hypertrophy; OR: odds ratio; RBBB: right bundle branch block; LBBB: left bundle branch block; SD: standard deviation. | ||||
