Non-Invasive Electrophysiological Mapping
NIEM (Non-Invasive Electrophysiological Mapping) is an innovative electrophysiological method based on non-invasive reconstruction of cardiac activation patterns from unipolar body surface potentials.
This method provides a non-invasive numerical reconstruction of endo- as well as epicardial electrograms in ventricles and atria. Mathematical algorithms applied to unipolar surface ECG data and 3D reconstruction of heart and thorax ensure high resolution of the method.
An automated analysis of reconstructed electrograms is used to map space-time dynamics of myocardial excitation process. This includes both focal as well as reentrant activation patterns.  Thus, exact and non-invasive electrophysiology mapping of the heart for topical diagnostics of heart rhythm disturbances can be achieved.
Non-Invasive Electrophysiological Mapping VS Invasive Electroanatomical Mapping
  • Non-invasive
  • Beat to beat simultaneous mapping for all four chambers of the heart
  • Simultaneous mapping on epi- and endocardial surfaces
  • Mapping of arrhythmias characterized by retrograde, aperiodical and reentrant processes
Clinical Application
Clinical application includes pre-operative diagnosis of complex heart rhythm disturbances. This includes therapy planning, monitoring as well as follow-up. Detailed topical and electrophysiological diagnosis allow to optimization of therapy and reduces intra-operative time. Risk of complications, fluoroscopy time, and accordingly patient and personnel radiation exposures are minimized. Optimization of cardiac resynchronization therapy provides another area of applications improving immediate as well as long-term results of therapeutic intervention.
  • EP and topical diagnostics of challenging arrhythmia cases prior to surgery or interventional ablation procedures
  • Post-procedure evaluations, repeated arrhythmia diagnostics
  • EP studies of patients, for which catheter EP studies are not recommended
  • Cardiac Resynchronization Therapy
