The intra-aortic balloon pump (IABP) is timed to deflate just before systole, specifically at the onset of the R-wave on the ECG. This timing allows for optimal coronary perfusion by promoting diastolic blood flow during the heart's relaxation phase. The balloon inflates during diastole to increase blood flow to the coronary arteries and deflates before the heart contracts to reduce afterload. Proper timing is crucial for maximizing hemodynamic support.
