Abstract

Aim: To determine if electrocardiogram (EKG) findings may be a useful tool to predict changes in repeat transthoracic echocardiogram (TTE). Methods: We evaluated patients who underwent TTE during hospitalization and their EKGs, and whether findings differed between studies. Results: Of 229 hospitalized patients who underwent repeat TTE, 183 (80%) were abnormal. Each minor and major EKG abnormality resulted in a 1.8 (1.2 to 2.6; p = 0.002) and 2.1 (1.3 to 3.3; p < 0.001) increased odds of abnormal imaging on TTE, respectively. The negative likelihood ratio for an unchanged EKG to predict an unchanged TTE was 0.68 (95% CI = 0.62 to 0.73). Conclusion: Among hospitalized patients with prior imaging results, an unchanged EKG predicts an unchanged TTE.
