This unique combination of the DR181 Holter recorder, Holter LX Analysis and Predictor® software gives physicians another value-added to their Holter system. With this combination one has the only clinically recognized way to use a Holter to perform SAECG (Signal Averaged ECG)/Late Potential (LP) analysis. For post-MI (myocardial infarction) patients, these measurements can be extremely predictive and valuable in prescribing additional testing and treatment.
