Background and Objective: organophosphorous (op) pesticides are one of the common compound used for poisoning, in severe forms, often leading to cardiovascular complication and death. Not many studies have been done to show the cardiac involvement in organophosphorus compound poisoning. Hence this is an attempt to study the cardiac complications in organophosphorus poisoning and to determine how it affects the outcome. Method: 50 patients with alleged history of organophophorus compound consumption with no prior cardiovascular comorbidites who admitted at KVG medical college and Hospital, sullia during the period of October 2019 to january 2021 were selected for the study. Results: In this study which included 50 patients of organophosphorus poisoning cases, Tachycardia (30%) was the most common clinical sign seen, followed by bradycardia (20%), hypertension (16%). Raised cardiac enzymes (Troponin T and CK-MB) were seen in 5 (10%) patients on day 3. The levels of Troponin T and CK-MB were elevated in patients with respiratory failure compared to non-failure ones. Conclusion: In this study tachycardia was found to be the most common clinical finding. Bradycardia was associated with severe poisoning. Q-T prolongation had a prognostic significance in determining death. The level of cardiac enzymes correlated well with the severity of poisoning and prognosis, suggesting its use as a prognostic indicator of organophosphorus poisoning.
