Abstract :

Introduction:Cardiac manifestations that occur in a majority of patients with organophosphate (OP) poisoning may range from sinus tachycardia, to life–threatening complications including cardiogenic pulmonary edema and myocardial necrosis. In this study, we evaluated the various electrocardiographic manifestations in patients with OP poisoning. Methods:This retrospective–descriptive study was performed by reviewing the medical records from 350 patients poisoned with organophosphate admitted to GMC Jammu from January 2018 to October 2018. Patients with incomplete records were excluded from the study and remaining 150 patients were included. Histories of all patients were collected and ECG analysis was conducted including the rate, rhythm, ST–T abnormalities, conduction defects, and measurement of PR and QT intervals. Descriptive statistical analysis was conducted by SPSS software version18. Results: Of the total 150 patients (100 were male and 50 females) with OP poisoning that referred to the GMC Jammu, 63 patients presented ECG abnormalities. The mean age of the patients was 35.78 ± 12.91 years. Sinus tachycardia (38.1%) was the most common ECG abnormality, followed by non–speciﬁc ST–T changes (25.4%). Overall, mortality rate was 5% in 150 patients and all of the deceased patients presented with changes in ECG. Conclusion: OP poisoning is associated with signiﬁcant ECG abnormalities, especially tachycardia and non–speciﬁc ST–T changes
