Remarkable flown Vectorcardiogram (VCG) electrode kit launched aboard Skylab I by a modified Saturn V on May 14, 1973, and returned to Earth on the Apollo CSM-116 spacecraft on June 22, 1973, used on astronaut Paul Weitz during the Skylab II mission, and signed and flight-certified on the top flap in black felt tip by Science Pilot Joe Kerwin: “This kit was used on all the Skylab 2 ‘active’ medical experiments (treadmill, LBNP). It’s Paul Weitz’s, and I brought it home when we reentered on June 22, 1973. (Each crew member had his own kit.) The exercise test was easy; the lower body negative pressure test tended to cause syncope. Joe Kerwin, Science Pilot, Skylab 2, May 25-June 22, 1973.”
The Beta cloth VCG electrode kit measures 7″ x 7″ x 7.75″, and features pouches to front and sides, each respectively marked “SPT,” “PLT,” and “CDR.” The top flap bears female button ends, Velcro arms extending to back, and the front and sides each marked “VCG Electrode Kit SL-2”; the top flap also features an annotated parts label: “VCG Electrode Kit, M093, Assy PN: SJC42100163-302, S/N: 007, Date of Assy: 4/16/73.” The interior of the kit consists of a multi-use storage container, which includes numerous packets of wet wipes, VCG sponges, and four electrode assemblies. In fine condition, with expected signs of use.
Accompanied by a letter of authenticity from David K. Broadwell of the Aerospace Medical Association Foundation, which reads: "This letter accompanies the Skylab II Vectorcardiogram (VCG) kit that was flown on-orbit aboard America’s first space station between May 25th and June 22nd, 1973. It was donated to the Aerospace Medical Association Foundation in 2019 by former astronaut Joseph P. Kerwin, M.D., the first physician in space and the Science-Pilot for the Skylab II mission. Dr. Kerwin was responsible for all the medical research done aboard the Skylab orbiting laboratory and used this kit on Skylab Pilot Paul Weitz. The kit was used for two medical experiments, M092 ‘In-flight Lower Body Negative Pressure’ and M093 ‘Vectorcardiogram’ (exercise test).”
