Quantitative Confounder Analysis of Electrocardiogram Signals in Cardiac Magnetic Resonance at 1.5, 3 and 7 T—Assessing Standardized Electrode Positions and Sequence Types—Towards Quality Assurance

Journal of Magnetic Resonance Imaging, Volume 63, Issue 4, Page 1140-1154, April 2026.
ABSTRACT Background The electrocardiogram (ECG) used for gating in cardiac MRI may be compromised by multiple confounders inside the scanner bore. Purpose To quantify the influence of magnetic field strengths (1.5 T/3 T/7 T), standardized electrode positions, and imaging sequences on ECG signals used for gating. Study Type Prospective.

AI‐Based Non‐Invasive Continuous Blood Pressure Monitoring and Estimation System

Advanced Sensor Research, Volume 5, Issue 1, January 2026.
An AI‐based biosensor pipeline integrates Apple Watch electrocardiogram (ECG), a custom digital stethoscope, and a blood‐pressure cuff to generate and validate 24‐hour cuffless blood‐pressure waveform prediction. Using a wavelet‐preprocessed ECG and a long short‐term memory model trained on MIMIC‐II and Autonomic Aging datasets, the system estimates ...
