Electrocardiogram and venous pressure curve with partial anomalous pulmonary venous return [C-wave appears before R-wave (arrow)].

Background
Central venous saturation and central venous pressure can be determined with central venous catheters. Therefore, the tip of the catheter should be located in the superior vena cava. The location can be monitored by electrocardiography or X-ray. The central venous pressure curve is displayed on the monitor. The reference value of central...

Context 1
... vena cava superior could not be seen. Monitoring demonstrated a venous-like pattern with a mean pressure of 16 mmHg (Figure 2). However, the shape of the curve seemed to be 'atypical' for a central venous pressure curve, as the C-wave of the central venous pressure curve represents tricuspid closure. ...
Context 2
... C-waves occur after the R-wave of the electrocardiogram ( Figure 3). In our patient, the C-waves appeared before R-waves (arrow, Figure 2). Thus, it became clear that the catheter was placed neither in a central vein nor in the left outflow tract. ...
Context 3
... Our case is interesting, because the diagnosis PAPVR was made by central venous catheterization data and not primarily from imaging. After conspicuous blood gas analysis was performed, further examination revealed that the venous curve was not in usual correlation to the Electrocardiogram (ECG) curve (Figure 2). The diagnosis was made through CT scanning (Figures 4 and 5). ...
