A Noise-Robust Model-Based Approach to T-Wave Amplitude Measurement and Alternans Detection
Zuzana Koscova, Amit Shah, Ali Bahrami Rad +3
T-wave alternans (TWA) is a potential marker for sudden cardiac death, but its reliable analysis is often constrained to noise-free environments, limiting its utility in real-world…
