Cardiac complications often accompany poisoning with organophosphates. These may be serious and often fatal, being represented by cardiac arrhythmias, electrocardiographic abnormalities and conduction defects, as well as myocardial infarction, a rarely reported complication of acute pesticide poisoning. The extent and pathogenesis of cardiac toxicity from these compounds is not yet clearly defined. We report the case of a 57-year-old woman who presented to our emergency department with coma and acute non-cardiogenic pulmonary edema, as a result of organophosphates ingestion. She was resuscitated for asystole presented shortly after admission; prolonged QTc interval, ST-T changes, right bundle branch block, ventricular tachycardia were recorded. Finally she developed acute anteroseptal myocardial infarction and died despite serum cholinesterase normalization. We believe that admission in an intensive care unit, careful electrocardiographic and enzymatic monitoring of all patients is important for the diagnosis and treatment of cardiac complications of organophosphates poisoning.

In addition to its crucial role in cardiac emergencies, ECG can be considered a very useful ancillary tool for the diagnosis of many non-cardiac diseases as well. In this narrative review, we aimed to explore the potential contributions of ECG for the diagnosis of non-cardiac diseases such as stroke, migraine, pancreatitis, Kounis syndrome, hypothermia, esophageal disorders, pulmonary embolism, pulmonary diseases, electrolyte disturbances, anemia, coronavirus disease 2019, different intoxications and pregnancy.Keywords: electrocardiography, electrocardiogram, features, non-cardiac diseases, ECG

Acute exposure to systemic poisons represents an important challenge in clinical toxicology. We aimed to analyze the potential role of cardiac biomarkers, routine laboratory tests, and clinical scores as morbidity and in-hospital mortality predictors in patients intoxicated with various systemic poisons. We conducted a prospective study on adults acutely exposed to systemic poisons. We determined the PSS, Glasgow Coma Scale (GCS), and we performed electrocardiogram, laboratory tests, lactate and cardiac biomarkers (which were reassessed 4 h, respectively 6 h later). Of 120 patients included, 45% developed complications, 19.2% had a poor outcome, and 5% died. Multivariate logistic regression sustained lactate (odds ratio (OR) 1.58; confidence interval (CI) 95%: 0.97–2.59; p 0.066), MB isoenzyme of creatine kinase (6h-CKMB; OR 1.08; CI 95%: 1.02–1.16; p 0.018) as predictors for a poor outcome. A GCS < 10 (OR 0.113; CI 95%: 0.019–0.658; p 0.015) and 4h-lactate (OR 4.87; CI 95%: 0.79–29.82; p 0.087) predicted mortality after systemic poisons exposure. Receiver operating characteristic analysis showed that brain natriuretic peptide (area under the curve (AUC), 0.96; CI 95%: 0.92–0.99; p < 0.001), lactate (AUC, 0.91; CI 95%: 0.85–0.97; p < 0.001), and 6h-CKMB have good discriminatory capacity for predicting a poor outcome. In conclusion, these biomarkers, lactate, and GCS can be used to predict morbidity and mortality after systemic poisons exposure. [ABSTRACT FROM AUTHOR]
