Fig. 16. Cannon a waves. A severely stenotic tricuspid valve or a junctional rhythm (atrium contracting against a closed tricuspid valve) causes a large a wave. The mechanical events of the waveform must be correlated with the electrical events of the electrocardiogram (ECG). CVP, central venous pressure. S1, heart sound 1; S2, heart sound 2.
