the study of various cardiac arrhythmias in patients poisoned with aluminum phosphide (rice tablet)

background: the poisoning is mostly due to suicide and is observed in younger age groups. the systemic manifestations of alp poisoning are common but pernicious manifestations of them are cardiotoxicity, shock, and ards. the clinical hallmark of cardiotoxicity is arrhythmia. the aim of this study was to investigate cardiac arrhythmias in patients poisoned with alp who were admitted to razi hospital to reduce mortality rate. methods: this survey was performed as a cross sectional descriptive study. overall, 102 patients were admitted to the hospital. their gender, age, first blood pressure (bp), and the number of consumed tablet were registered. a cardiologist studied the patients’ ecgs and recorded various arrhythmias. then, data were analyzed using spss version 11. results: in this study the mean age was 29.75±14.34 years and 66.7% of the patients were male. used tablet and first bp average were 1.74±1.25 and 69.51±27.31 mmhg, respectively. arrhythmia was recorded in 75.5% of the patients, among which arterial fibrillation (af) was the most prevalant with the rate of 40.3%. pvc, junc and pac were the most common arrhythmias, respectively. another arrhythmia was categorized in one group. all kinds of arrhythmia were common in younger males who had used more than one tablet and had first bp less than 90 mmhg. all patients with arrhythmia died. conclusion: cardiotoxicity is an important cause of death in all studies and in this study as well. all patients with arrhythmia, demonstrated through ecg, died. therefore, this study can be the basis for more detailed studies.
