WebCardiac resynchronization therapy (CRT) is a type of treatment to help correct serious heart rhythm problems. It involves placing a device under your skin that is connected to the heart's ventricles. The device sends electrical signals … WebThe paced AV delay range for the AdaptivCRT function is between 100 ms and 180 ms. The corresponding V-V pacing delay range for the AdaptivCRT function is between 0 ms and 40 ms (left or right pre-excitation). The first step of optimization is an assessment of atrioventricular conduction. In this patient, the delay between spontaneous atrial ...

The greatest impact of VV optimization is seen in patients where there is a marginal discrepancy between the region of maximal delay and the position of the LV lead, suggesting that VV optimization can overcome …
WebSep 1, 2012 · Significant correlation appeared to exist during optimization of CRT between VV programming based on the shortest QRS interval at 12-lead ECG pacing and that based on highest LVOT VTI by echocardiography. A combined ECG and echocardiographic approach could be a more convenient solution in performing V–V optimization.
