Machine learning-based multichannel short-duration high-dynamic microvolt T-wave alternans detection

Qingfeng Pei, Changrong Ye, Xu Li, Junhong Lv

Microvolt T-Wave Alternans (MTWA) is a widely recognized predictor of sudden cardiac death (SCD). However, its detection is challenging due to the microvolt amplitude of alternans, the presence of short-term high dynamics, and low signal-to-noise ratios in clinical electrocardiogram (ECG) signals. This …
