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.

Reconstructing a 12-lead surface ECG from intracardiac EGM vectors of patients implanted
with defibrillators can be of great value. It allows implantable devices that have thus far
been used exclusively for arrhythmia detection and treatment, to be used for diagnostic
purposes in similar ways as the ECG. The advantage of the reconstruction process is that it
provides real-time continuous monitoring, which can be used for multiple purposes, including
but not limited to:
1. Ischemia detection
2. Myocardial Infarction detection
3. Electrolyte abnormalities detection
4. Assessment of effect of medications
5. Improved rhythm discrimination
