ECG delineation techniques and applications in Cobra venom interacted patients

ECG signal provides a dynamic assessment of the cardiac activities. To analyze the ECG signal, some innovative ECG delineation techniques along with a few known techniques were used to provide the optimum strategy for marking of events. The techniques were applied on 125 records of CSE DS-3 database for calibration and subsequently, on the data acquired from no known-cardiac Cobra bitten patients under strict ethical protocol and medical supervision. Cobra bite cases are commonly observed in India. The ECG morphology changes due to Cobra venom interaction may be attributed to the cardio-toxins present in the venom and their synergistic effect with other venom constituents. A study was conducted to observe relationship between cobra venom interaction and the ECG wave parameters changes. The study included patients, accidentally interacted with Cobra venom and with no known cardiac disease history. This study provided significant visible effects of Cobra venom in the ECG waves and manifested some specific morphological changes.
