NCT05010655

Brief Summary

The purpose of this research is to prospectively test and validate the single-lead Low EF algorithm in outpatients in order to test the performance of a single-lead ECG based algorithm to identify people with decreased left ventricular EF.

Sampling MethodNon-Probability Sample
Study Population

Patients undergoing a transthoracic echocardiogram will be enrolled. Patients who are over the age of 60 or who are at risk for heart failure (hypertension, murmur, etc.) will be targeted for enrollment. We will also target patients with a referral diagnosis of dyspnea on exertion, orthopnea, lower extremity edema, and possible heart failure.

You may qualify if:

  • English-speaking adults who are 18 years and older
  • Able and willing to provide informed consent
  • Complete a clinical echocardiogram within 7 days before or after study procedures

You may not qualify if:

  • Unwilling or unable to provide informed consent
  • Patients who are hospitalized
