Figure 2From: Case study to assess the safety of irreversible electroporation near the heart Electrocardiogram during IRE treatment. A: Tracing obtained during IRE treatment of the hepatic mass in segment 4 with the synchronization device. The distance from the electrode to the inferior border of the heart is 1.7Â cm based on US measurement. IRE pulses are incorrectly delivered on the T wave (arrows), resulting in an episode of ventricular extrasystoles (asterisks). B: The synchronization device failed to operate properly during treatment.Back to article page
