Pick from 16 conditions to see the classic cath-lab pressure tracing, synchronised to the ECG, with the a / c / v waves and x / y descents labelled on the RA and wedge. Toggle each chamber’s wave on or off, overlay the normal curve, and — for conditions that respond to breathing — turn on Breathing to watch pressures change live and connect the systolic peaks (the oblique line shows RV rising while LV falls on inspiration in constriction).
Educational illustration for students & trainees. Waves are stylised, physiology-based teaching models — not real patient tracings or clinical guidance.
