Cook Pacemakers Sensor Kelvin Model 504 central-venous-temperature-sensing rate-responsive pacemaker

In 1983, Bill Cook and Dr. Neal Fearnot began to work under the Cook Pacemaker Company in Leechburg, PA on developing the technology developed by Dr. Fearnot at Purdue University into an improved prototype for a temperature-based exercise responsive pacemaker that was released in 1988 as the Kelvin Sensor rate-responsive pacemaker.  One of the first CVT rate-adaptive pacemakers was the Cook Model Kelvin 500 series.

Cook Pacemaker's Kelvin and Intermedics' Circadia central venous temperature-controlled rate-responsive pacemakersOne of the indicators of metabolic demand that has been used for controlling the rate of pacemakers is central venous blood temperature (CVT).

In 1983, Bill Cook and Dr. Neal Fearnot began to work under the Cook Pacemaker Company on developing the technology developed by Dr. Fearnot at Purdue University into an improved prototype for a temperature-based exercise responsive pacemaker that was released in 1988 as the Kelvin Sensor rate-responsive pacemaker.  One of the first CVT rate-adaptive pacemakers was the Cook Model Kelvin 500 series.

Another one of the first CVT rate-adaptive pacemakers was the Intermedics Nova MR, which differs from the Kelvin 500 series in that its pacing algorithm had a more dynamic HR response. Continue reading→
