ECG-Electrocardiography OP-Organophosphorous Poisoning Hypokalemia

Introduction:Organophosphorous poisoning is one among the most common poisoning seen in India due to its easy availability and accessibility.It has varied mechanism by which it damages the human system.cardiovascular toxicity is one among the many.Serum Magnesium level also plays a role in prognosis of OP poisoning .In this Study we have tried to study varied Ecg manifestations and magnesium levels in op poisoning cases attending K R Hospital,mysore . Materials And Methods:This was a cross sectional study, and data was collected from the routine investigations of the cases and secondary sources from published journals . The data was analysed by SPSS software version 20 and chi square test was applied for qualitative variables. Results:In 50 OP poisoning cases studied with (male- 43 ,Female- 7)with mean age of 43 among males and 34 among females,the commonest poison consumed was chlorpyrifos(24).ECG Findings showed Sinus Tachycardia (38%)as the most common manifestation in my study with Normal sinus Rhythm (20%) Second most common finding,QT prolongation(18%),St-t changes(12%),Premature ventricular complex(6%),Sinus bradycardia(2%),Ventricular tachycardia(4%).Hypokalemia was seen in 17 patients with mean of 3.45 among Female and 3.70 among Males.Mean Serum magnesium was 1.73 among males and 1.64 among Females.MeanPseudocholinesterase level observed was 1885. Conclusion: Subjects with Hypokalemiaand sinus Tachycardia and Qtprolonation had a high mortality and morbidity as compared to other subjects.
