NIT-R develops new atrial lead system for arrhythmia detection
Bhubaneswar/Rourkela: Researchers from NIT-Rourkela designed a novel lead placement system called the (ALS) using the electrocardiogram (ECG) machine and its electrodes to detect irregular heart rhythms, or arrhythmias, responsible for a large number of cardiac-related deaths around the world. Tired of too many ads? go ad free now Usually, doctors or healthcare workers use an connected with 12 electrodes to measure the electrical activity of the heart by placing the electrodes on different parts of the body. Lead wires are connected with the electrodes and the ECG machine. In an ECG, doctors check the 'P-wave', which reflects the electrical activity in the upper chambers of the heart. However, P-waves are often small and easily lost in background noise or obscured by stronger signals from other parts of the heart. As a result, detecting atrial arrhythmias can sometimes be difficult, particularly in busy clinical settings or with low-cost monitoring equipment, said the researchers. J Sivaraman, research lead and assistant professor, department of biotechnology and medical engineering, NIT-Rourkela, said lead placement involves positioning these electrodes to capture clear signals from the heart. Placing three leads and positioning the electrodes at the right place on the chest brought wonderful results in improving the accuracy of , he added. "The ALS uses a modified arrangement to improve how electrical activity from the atria is recorded. By strengthening these signals, especially the P-wave, the system helps improve the accuracy of arrhythmia detection, both by doctors and by computer-based diagnostic tools," he added. Other researchers were N Bala Chakravarthy and Kunal Pal, along with research scholars Prasanna Venkatesh and Arya Bhardwaj from NIT-Rourkela, with clinical collaborations and validation provided by Dr R Pradeep Kumar, Institute of Cardiac Care, MIOT International, Chennai. Tired of too many ads? go ad free now Findings of this research were published in international journals, including Biomedical Signal Processing & Control, Medical Hypotheses, and Physical & Engineering Sciences in Medicine. The research team also filed a patent application for the atrial lead system. This new system helps in easily detecting subtle electrical signals from the upper chambers of the heart, which are often too indistinct to be seen clearly in regular ECGs. These signals play a key role in identifying abnormal heart rhythms that can lead to serious conditions such as , which can further lead to stroke, said Dr R Pradeep Kumar. Irregular heart rhythm in the heart's upper chambers, known as atrial arrhythmias, are among the most common, especially in patients who were hospitalised. Identifying these arrhythmias in an early state can help doctors begin timely treatment and prevent complications, said Sivaraman. The ALS mechanism requires no change to the ECG machine itself. The innovation lies entirely in the way the leads are placed, which means the upgrade can be easily adopted in both public and private healthcare settings without additional cost, said the researchers.

Nemom cooperative bank fraud inquiry report reveals massive financial irregularities
Thiruvananthapuram: After a long delay, the inquiry team of the cooperative department submitted a report on the surrounding Nemom Service Cooperative Bank, on Wednesday. The inquiry was conducted based on Section 65 of the State .The delay in completing the inquiry attracted the wrath of the depositors, whose money was allegedly defrauded by the administrative panel members of the bank. Tired of too many ads? go ad free now The report found an irregularity worth Rs 100 crore at the bank. More details about the report are yet to come out. "The report has just been submitted and it has to be checked to comment more on it," said Ayyappan Nair, joint on the report, the department will be able to initiate proceedings against the accused as per Section 68 (1) and 68 (2) of the cooperative rules, the officer the basis of the report, the quantification of the total irregularity will be done by a team of officials as per Section 68 (1). The team will assess the preliminary inquiry report and it will be matched with the bank accounts to ensure accuracy on the total amount quantification is over, the liability of each accused will be calculated by considering their roles in the fraud. "Suppose if Rs 10 crore is the total amount lost, a share of it will be divided among the accused by considering their roles in the fraud. After this process, they will be summoned to hear their part and a final recovery order will be issued as per Section 68 (2)," added the the meantime, the enforcement directorate (ED) has registered a case over the irregularities and began a March this year, the former member of CPM Nemom area committee and former president of the bank R Pradeep Kumar was arrested by the economic offence wing (EOW) of the crime branch team probing the case.
