Fig. 1 Hemodynamic effect of simultaneous atrial and ventricular contraction in 60-year-old patient with junctional rhythm spontaneously converting to a sinus mechanism. Left ventricular systolic pressure (scale 0 to 100 mm Hg) increases from 90 to 150 mm Hg, while right atrial pressure (scale 0 to 25 mm Hg) decreases with disappearance of cannon wave (arrow). Time lines are at 1-second intervals.
