Mintek Pacemaker LV-T Manuale Utente

Stratos LV/LV-T Technical Manual  85 

 

Lead Check – Lead check will not lead to disabling of cardiac 
resynchronization therapy. It limits the use of the 
resynchronization features.  

1.  Lead check is possible only when the right ventricle is 

paced first. 

2.  Lead check works only when the pacing voltages are 

programmed between 2.4 and 4.8 V.  The lead check 
feature can be programmed OFF in patients that 
require cardiac resynchronization therapy.   

Care should be taken when programming Stratos CRT-Ps 
with Lead Check ON as the device may switch from bipolar to 
unipolar pacing and sensing without warning.  This situation 
may be inappropriate when using a Stratos CRT-P for patients 
with an Implantable Cardioverter Defibrillator (ICD). The 
following associated message appears when programming 
this feature: 

“Lead check may result in a switch to unipolar pacing and 
sensing, which may be inappropriate for patients with an 
ICD.” 

Additionally, Lead Check should be programmed OFF before 
lead connection as the feature will automatically reprogram 
the device to unipolar in the absence of a lead.  

 

Lead Check is temporarily suspended during magnet application 
and is inactive during ERI.  

In the Stratos CRT-Ps, an automatic lead check cannot be 
programmed ON if left ventricular paces are programmed to 
occur before right ventricular paces.
