Understand ventricular activation during pacing
Conduction System Pacing
Ventricular Electrical Delay (VED or e-DYS)
Calculation available in automated and manual models
From high-fidelity ECG to UHF-ECG map
Advanced processing of ultra-high-frequency μV signals
High-frequency signal propagation is short
Tt is more location specific than regular ECG signal
From the high frequency ECG to Activation Map
How UHF-ECG works
12(14) lead ECG setup is all to start to meassure
No need to couple with pre-procedural CT/MRI imaging
UHF-ECG signal is location specific.
UHF-ECG captures the activation of the myocardial segment under each chest lead.
Instanteneous visualization of ventricular activation
VDI UHF-ECG System helps during pre-operative patient selection, implant procedure, and post-operative care.
Records UHF-ECG ventricular activation V1 - V8.
Depolarization of the myocardial cells that work as transmitters generates a UHF electrical signal (150 -1,000 Hz)
Synchronous UHF-ECG activation example
All ventricular segments under chest leads are activated almost at the same time.
Dyssynchronous UHF-ECG activation
Dyssynchronous activation shows a significant time delay between individual chest leads.
Ventricular activation vizualization
UHF-ECG activation sequence describes the time difference between the activation of ventricles
Ventricular Electrical Delay (VED or e-DYS) calculation is available in automated and manual modes.
