Reconstruction of 12-Lead Electrogram From Intracardiac Signals From Defibrillators During or After Implantation

NCT00890461 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 42

Summary

The purpose of this study is to reconstruct a 12-lead electrocardiogram (ECG) from intracardiac (IC) electrograms (EGM) obtained from defibrillator devices (ICD). The purpose of such a reconstruction is to allow the use of IC EGM for diagnosis of clinical conditions for which ECG have historically been used, and to test the feasibility of a reconstruction technique for the standard 12-lead or extended electrocardiogram from electrical potentials obtained from inside a patient.

Conditions

  • ICD

Interventions

RADIATION

CT scan of the chest without contrast

Patients consenting to participate in the study may also undergo a baseline CT scan of the cest without contrast to allow for the geometrical characterization of their intracardiac electrodes from the ICD system in relation to the position of the 12-lead surface ECG electrodes which would be applied to the chest prior to the CT scan. This scan involves a small amount of radiation, a dose of approximately 1 rem. For comparison, radiation workers are permitted, by federal regulation, a maximum annual radiation exposure of 20 rems to the most sensitive organs of their body.
