Why the study?
Does a tangent-intersection-based slope algorithm improve QRS localization precision compared to standard QRS detectors and cross-correlation methods in ECG recordings?
Does a tangent-intersection-based slope algorithm improve QRS localization precision compared to standard QRS detectors and cross-correlation methods in ECG recordings?
A novel, low-complexity slope-based algorithm provides precise QRS localization comparable to computationally expensive cross-correlation methods, making it suitable for real-time applications in low-power embedded devices.
