Abstract

Physiological monitoring of cardiac deformation can lead to a better understanding of cardiac function. The use of telemetry during monitoring can provide a more comprehensive study of conformation changes under natural and unnatural cardiac stress conditions. The data from piezoelectric crystals used to measure the conformational change is converted into a digital time measurement. This time measurement is buffered in DRAM and then sent to the radio frequency transceiver by a PIC microcontroller to be transmitted to the PC. This design provides an integrated system for radio frequency telemetry of sonomicrometry
