Abstract：Objective To investigate the electrocardiogram（ECG）changes on patients with poisoning by ingesting porcine thyroid and patients with hyperthyroidism. Methods ECGs were analyzed to study the changes of 27 patients with poisoning by ingesting porcine thyroid，85 patients with hyperthyroidism and 85 persons who received health check up were served as control group. Results The incidences of arrhythmia，ST-T changes and left ventricule hypervoltage were the same in poisoning group and hyperthyroidism group. There was no statistic difference of ECG changes between two groups（P >0.05）. The most frequent abnormality of two groups was sinus tachycardia and ST-T changes. But these two groups were both had statistically difference with persons who received health check up. Conclusion The ECG changes on patient with poisoning by ingesting porcine thyroid has no statistic difference with patients with hyperthyroidism. But they both had statistically difference with persons who received health check up，indicated that the elevated thyroid hormone might account for the ECG changes on patients with ingesting porcine thyroid gland and patients with hyperthyroidism.
