The present study aims to determine the effects of long-term exposure to electromagnetic radiation from mobile phones (MPs) on heart rate variability (HRV), cardiac function, blood profiles, body surface temperature, and semen quality in healthy dogs. Eight male dogs were exposed to MPs (1962-1966 MHz; specific absorption rate 0.96 W/kg) for 2 h/day, 5 days/week, for 10 weeks. Holter monitoring for HRV analysis was performed at baseline (BL) and every 2 weeks, until the end of the study. Electrocardiograms (ECG), blood pressure (BP), echocardiography, cardiac troponin I (cTnI), hematology and biochemistry profiles, body surface temperature, and semen quality were evaluated at BL, week 5, and week 10 during exposure. The results showed that most of the HRV parameters did not significantly differ among timepoints, except for the mean of an interval between continuous normal R waves in week 6 that was higher than that at BL ( = 0.022). The RR and QT intervals from ECG in week 5 were prolonged, compared to the BL values ( = 0.001 and = 0.003, respectively), but those parameters were within the normal limits. The echocardiography, BP, cTnI concentrations, body surface temperature, and semen quality results were not different from BL values. In conclusion, this study found no evidence suggesting an adverse effect of cell phone exposure on HRV, cardiac function, blood profiles, body surface temperature, or semen quality in healthy dogs, when exposed for 10 weeks.
本研究旨在确定长期暴露于手机发出的电磁辐射对健康犬的心率变异性（HRV）、心脏功能、血液指标、体表温度和精液质量的影响。八只雄性犬每天暴露于手机辐射（1962 - 1966兆赫；比吸收率0.96瓦/千克）2小时，每周5天，持续10周。在基线（BL）时以及每2周进行一次动态心电图监测以分析HRV，直至研究结束。在暴露期间的BL、第5周和第10周评估心电图（ECG）、血压（BP）、超声心动图、心肌肌钙蛋白I（cTnI）、血液学和生化指标、体表温度以及精液质量。结果显示，除第6周连续正常R波间期的平均值高于BL时（P = 0.022）外，大多数HRV参数在各时间点之间无显著差异。与BL值相比，第5周ECG的RR和QT间期延长（分别为P = 0.001和P = 0.003），但这些参数仍在正常范围内。超声心动图、BP、cTnI浓度、体表温度和精液质量结果与BL值无差异。总之，本研究未发现证据表明健康犬在暴露10周时，手机辐射会对HRV、心脏功能、血液指标、体表温度或精液质量产生不良影响。
