The real-time processing and transfer of ECG (Electrocardiogram) signals using mobile phones have become increasingly important in modern healthcare systems. This paper presents a system that captures ECG signals from a patient via a portable ECG sensor, processes the data in real time on a mobile device, and transfers it to healthcare professionals or remote monitoring systems through wireless networks. The proposed system leverages the processing power of modern smartphones to filter, analyze, and extract significant features from the ECG signals, such as heart rate and arrhythmia detection, using signal processing algorithms. By using mobile communication technologies (e.g., 4G/5G), the processed data is then transmitted to cloud servers or medical centers, enabling continuous monitoring and timely diagnosis. This approach enhances patient mobility, reduces the need for bulky medical equipment, and supports real-time decision-making for critical heart conditions. The system also integrates user-friendly interfaces, ensuring accessibility for both patients and clinicians. Initial results demonstrate the system's efficiency in providing accurate ECG analysis with low latency, showing potential for widespread use in telemedicine and remote healthcare monitoring applications.
