Waveform
Early Inflation 1
- Potential premature closure of aortic valve
- Reduction in cardiac output
- Increased LVEDV and LVEDP
- Increased myocardial oxygen consumption.
- Balloon inflates before dicrotic notch
- Diastolic augmentation encroaches onto systole
- May be difficult to distinguish between two peaks
