This paper illustrates a method for time-plane feature extraction from digitized ECG sample using statistical approach. The algorithm detects the position and magnitude of the QRS complex, P and T wave for a single lead ECG dataset. The processing is broadly based on relative comparison of magnitude and slopes of ECG samples. Then the baseline modulation in(More)
This paper illustrates a simple algorithm for real time QRS detection from ECG data. The algorithm is implemented on Xilinx field programmable gate array using very small number of memory cells. Single lead Synthetic ECG using ptb-db database (from Physionet) is generated from a personal computer using the parallel port (LPT1) at 1 ms sampling interval and(More)
The field of health research appears increasingly open to qualitative approaches. We celebrate the rise in qualitative and mixed methods publications and the marked presence of qualitative researchers in academic centres of health research. However, we note enduring tensions between the conceptual and methodological approaches of qualitative research and(More)
