This true-time model analyzes the sign from one-lead ECG sensor to classify beats and detect irregular heartbeats ('AFIB arrhythmia'). The model is intended to be able to detect other sorts of anomalies including atrial flutter, and will be repeatedly extended and enhanced. 8MB of SRAM, the Apollo4 has in https://ambiq.ai/community/deploying-edgeimpulse-models-using-neuralspot-nests/
