May support remote ECG monitoring via implants; hypothesis-generating and requires validation in arrhythmias and larger cohorts.
Effect estimate: Correlation coefficient ~0.85
A novel PCA-based method can synthesize 12-lead surface ECGs from intracardiac electrograms with high correlation during sinus rhythm, potentially enabling remote monitoring of standard ECGs via implantable devices.
Kachenoura et al. (2008) studied Patients with cardiac implantable devices (n=12). Patient-specific ECG synthesis using intracardiac vectorcardiographic loop and principal component analysis vs. Standard 12-lead surface ECG was evaluated on Correlation coefficient between real surface ECG and synthesized ECG (Correlation coefficient ~0.85). A patient-specific method using principal component analysis synthesized surface ECGs from intracardiac electrograms with a correlation coefficient of approximately 0.85 compared to real ECGs in patients with sinus rhythm.
