Healthcare issues arose from population aging. Meanwhile, electrocardiogram (ECG) is a powerful measurement tool. The first\nstep of ECG is to detect QRS complexes. A state-of-the-art QRS detection algorithm was modified and implemented to an\napplication-specific integrated circuit (ASIC). By the dedicated architecture design, the novel ASIC is proposed with 0.68mm2\ncore area and 2.21 �µW power consumption. It is the smallest QRS detection ASIC based on 0.18 �µm technology. In addition, the\nsensitivity is 95.65% and the positive prediction of the ASIC is 99.36% based on the MIT/BIH arrhythmia database certification.
