What key physiological parameter did the 1967 NASA-funded program aim to transmit wirelessly from heart patients' homes?

Electrocardiograms (ECG)

A significant transition point from theoretical prediction to practical deployment occurred around the mid-1960s when aerospace telemetry principles were adapted for ground applications. One notable example, supported in part by NASA funding, was a program initiated in 1967, often linked to the University of Minnesota, focusing on monitoring cardiac patients within their own residences. The goal of this tangible effort was to develop devices capable of capturing critical physiological metrics, specifically electrocardiograms (ECG), and transmitting these readings wirelessly back to a central monitoring station. This demonstrated a clear move toward device deployment for continuous monitoring in non-specialized environments, such as a patient's home.
