This is a study to determine the feasibility of obtaining information stored in existing
Medtronic internal defibrillators in patients who present to the Emergency Department(ED)
for any reason. In addition, the study will determine if this information is useful to the
ED physician in managing the patient's care, specifically as it relates to heart failure.
This is a prospective observational pilot study to determine if stored data regarding heart
function, patient activity level, and other parameters can be used by the ED physician in
order to evaluate a patient's cardiac status as it pertains to heart failure. Patients
presenting to the ED and who consent have their devices interrogated by research personnel.
The data is printed and provided to the treating physician who completes a brief survey
about whether the data was useful in managing the patient.All subjects are contacted 30 days
after ED or hospital discharge to determine if they have had any ED visits or hospital
admissions during that period, and if yes, whether the visits were heart failure related.
After all study procedures are performed, a team of 2 cardiologists will review the patient
medical record from the study visit, as well as the data obtained from the patient's device
in the ED. Each cardiologist, who will be blinded to the other's conclusion, will determine
if the patient was having a heart failure exacerbation at the study visit.
