Ra waveforms
WebJun 5, 2024 · The RA pressure waveforms were evaluated by a cardiologist and a cardiovascular surgeon independently in a blinded fashion. We determined the relative depth of the nadirs of “X” and “Y” descents. In a patient with normal RV function, the X descent nadir is usually deeper than that of Y descent (Figure 2A).

Several waveform retracking algorithms have been developed to overcome the signal contamination problem.
WebIntracardiac lines include Direct Left Atrial (LA), Direct Right Atrial (RA) and Pulmonary Artery Line (PA). These lines are inserted directly into the heart usually in the operating theatre under direct vision. They are secured with a purse string suture to the epicardium and exit the mediastinum via the chest wall. WebOct 15, 2016 · Mechanism: In cardiac tamponade, there is compression of all cardiac chambers due to increased pericardial pressure. As cardiac tamponade progresses, the cardiac chambers become obliterated, and chamber diastolic compliance is reduced. Eventually, venous return drops.
