Figure 1.
Example of combined MII/pH and SC monitoring.
Capital letters A to G represent seven consecutive 120-second intervals. The upper blue line represents the SC signal; black and gray arrows indicate stress-positive and stress-negative intervals, respectively. The lower red line represents pH monitoring; each of the six colored lines in the middle indicates one of the six MII channels (starting from the top at channel 1); the yellow vertical stripes indicate reflux events. The intervals A, D and G are negative for the both presence of reflux and stress. The interval B is positive for both reflux and stress. The intervals C and F are positive for stress only. In the interval E, a stress-negative reflux occurs.
