Atrial & ventricular based timing

Occurs in dual chamber modes only

​

Determines the response to a sensed ventricular event

​

Ventricular Based Pacing

•Rate is driven by the VA interval

​

Atrial based pacing

•Modified atrial based timing

•Rate is driven by the LRI (AA/VV) except after a PVC, it follows the VA interval

•Pure atrial based timing

•Rate is driven by the LRI (AA interval)
