Figure 4. Effects of RI with mild renal insufficiency on the occurrence of AF (n = 5).

Effects of embolization versus sham operation on inducibility of AF (A) and on the duration of induced AF episodes (B) in dogs. Representative right atrial potentials and ECG recordings after 10 seconds of rapid atrial pacing at baseline and with RI after 2 weeks of embolization in the model group (C).
