In this case the ECG is derived through a fluid column. The catheter is first connected with a three-way valve, which is in turn connected to the DeltaLong SwitchBox via a connecting cable. The syringe is then filled with an electrically conductive solution and connected to the DeltaLong three-way valve. When the valve is opened, the catheter can be completely filled with the electrically conductive solution. This creates a fluid column by which an intra-atrial ECG can be derived.
Easier to useThe three-way valve rotates through 360° for greater ease of use. It can be opened and closed in both directions.
