The balloon itself has a pressure transducer, and it generates a waveform. About 40 milliseconds before the dicrotic notch, the IABP balloon inflates. This is timed with the ECG, usually - the end of the T wave is used as a marker that systole has finished. Why the delay? because even the best IABP pistons require a few … Ver mais The aortic pressure waveform generated by the deflation and inflation of the balloon demonstrates some of the hemodynamic effects of IABP counterpulsation. Ver mais Apart from ECG triggering, other methods exist: Pacemaker timing: this is a well-practised technique (it seems to have first been described in a … Ver mais The waveform in the diagram above is slightly exaggerated, in order to simplify the explanations. In that diagram the graphical representation of the events occurring around the … Ver mais WebThe P-wave is virtually always positive in leads aVL, aVF, –aVR, I, V4, V5 and V6. It is negative in lead aVR. The P-wave is frequently biphasic in V1 (occasionally in V2). The negative deflection is normally <1 mm. P-wave duration should be ≤0,12 seconds. P-wave amplitude should be <2,5 mm in the limb leads.

WebFig. 19.5. Intra-aortic balloon pump aortic waveform. The IABP inflates at the timing of aortic valve closure or the dicrotic notch on the aortic pressure waveform. Inflation results in diastolic augmentation that is higher pressure than unassisted systole, which results in increased coronary blood flow and MAP. IABP deflates just prior to ...
