Arrhythmia induced by acute organophosphorous pesticide poisoning: a literature review / 中华全科医师杂志

Literatures on arrhythmia induced by acute organophosphorous pesticide poisoning published in domestic journals from 1979 to 2010 were searched. Total 3468 cases of acute organophosphorous poisoning were collected and analyzed. The average abnormal ECC rate was (53 ±15)%(35. 4% -68. 4% ) in acute organophosphorous poisoning, the most common ECG abnormalities were ST-T segment changes (26. 5% ) and sinus tachycardia (16. 6% ). The rate and severity of ECG abnormalities were increased with the severity of organophosphorous poisoning(x2 = 33. 253,P < 0. 01). The most common causes of death in acute organophosphorous poisoning were ventricular tachycardia and ventricular fibrillation (26.2%).
