A Frequency-Domain Framework for Cardiovascular Power Distribution
Raje, A. A.
Show abstract
Traditional cardiovascular models emphasize time-domain dynamics of blood flow and pressure, such as cardiac output and mean arterial pressure. However, the pulsatile nature of blood flow contains rich frequency content that interacts uniquely with organ-specific vascular properties. Drawing on wireless power transfer principles from electrical engineering, we propose a frequency-domain framework where the heart functions as a multi-frequency power source, generating a complex pressure waveform with multiple harmonics, and organs act as frequency-tuned loads, selectively absorbing power at their characteristic vascular resonance frequencies. This model introduces a frequency-division multiplexing analogy for cardiovascular power distribution, offering insights into physiological regulation, disease mechanisms, and therapeutic strategies. We present the theoretical foundation, mathematical models, physiological evidence, and potential clinical applications, supported by preliminary simulation results.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
