While long-distance running has important health benefits, chronic elevation of blood pressure during exercise might induce cardiac events and sudden death. This study aimed to investigate characteristics of exercise and incidence of abnormal exercise electrocardiography findings in long-distance runners with exercise-induced hypertension. Long-distance runners (n = 606) underwent a questionnaire survey, history taking, and exercise stress testing, and they were classified into the non-exercise-induced (n = 268) and exercise-induced (n = 338) hypertension groups. Exercise-induced hypertension was defined as systolic blood pressure ≥210 mm Hg during maximal exercise. Abnormal electrocardiogram response (AER) were defined as abnormal electrocardiography findings, such as arrhythmias or ST-segment changes, during exercise stress testing. There were no differences in general and exercise-related characteristics between the non-exercise-induced and exercise-induced hypertension groups. The AER group (AERg, n = 37) had a significantly longer training history and total exercise time than the non-AER group (non-AERg, n = 569) (p < .05). Atrial arrhythmias and ST-segment depression were more prevalent in the exercise-induced hypertension group than in the non-exercise-induced hypertension group (atrial arrhythmias: 5% [17/338] vs. 1.9% [5/268]; ST-segment depression: 2.7% [9/338] vs. .4% [1/268]; p < .05). The incidence of AER was significantly higher in the exercise-induced hypertension group (n = 30, 8.8%) than in the non-exercise-induced hypertension group (n = 7, 2.6%) (p < .05). This study showed that long-distance runners with AER had a longer training history and total exercise time than those without AER, and the exercise-induced hypertension group had a higher rate of AER.
虽然长跑对健康有重要的益处，但运动过程中慢性血压升高可能会引发心脏事件和猝死。本研究旨在探讨运动引起的高血压患者的运动特征和异常运动心电图发现的发生率。长跑运动员（n=606）接受了问卷调查、病史采集和运动压力测试，并分为非运动引起（n=268）和运动引起（n=338）高血压组。运动引起的高血压定义为最大运动时收缩压≥210mmHg。异常心电图反应（AER）定义为运动压力测试期间出现心律失常或 ST 段改变等异常心电图表现。非运动引起和运动引起高血压组在一般和运动相关特征方面无差异。AER 组（AERg，n=37）的训练史和总运动时间明显长于非 AER 组（非 AERg，n=569）（p<0.05）。运动引起的高血压组比非运动引起的高血压组更常见房性心律失常和 ST 段压低（房性心律失常：5%[17/338] vs. 1.9%[5/268]；ST 段压低：2.7%[9/338] vs. 0.4%[1/268]；p<0.05）。AER 的发生率在运动引起的高血压组（n=30，8.8%）明显高于非运动引起的高血压组（n=7，2.6%）（p<0.05）。本研究表明，AER 的长跑运动员的训练史和总运动时间长于无 AER 的长跑运动员，且运动引起的高血压组 AER 的发生率更高。
