Figure 1 Curves of 24-h intra-esophageal pH monitoring and Holter electrocardiography in a patient with abnormal gastroesophageal reflux show the decreasing amplitude of the ST segment. A: Ranged from 0.05 mV to 0.15 mV in 9 min. The results also indicate that abnormal gastroesophageal reflux occurred during this period; B: 0.1 mV to 0.3 mV in from 12:38:07 to 20:50:02. The results also indicate that abnormal gastro-esophageal reflux occurred during this period.
