Title: Innovations by James T. Bartelt in Cardiac Technology

Introduction

James T. Bartelt is an accomplished inventor based in Shoreview, MN (US). He has made significant contributions to the field of cardiac technology, holding a total of 3 patents. His work focuses on improving the performance and testing of cardiac pacer devices, which are crucial for patients with heart rhythm disorders.

Latest Patents

One of Bartelt's latest patents is the "Cardiac Pacer Testing System." This innovative device is a hand-held, portable, battery-powered instrument designed to evaluate the performance of cardiac pacer devices before and after implantation. The system tests the R-wave sensitivity of a pacer device by applying a series of simulated R-waves of predetermined amplitudes. This process continues until a succeeding pacer pulse does not occur, indicating that the R-wave has reached the necessary amplitude to reset the pacer pulse generator. The device displays the minimum amplitude of the R-wave required for pacer resetting in terms of voltage.

Another notable patent is the "Midpoint Measuring Circuit." This apparatus measures the amplitude of an adjustable width current or voltage impulse at a known time interval following the initiation of the impulse. During the first pulse duration, a counter is advanced with clock signals. The accumulated total is then transferred into a downcounter, which is decremented during a second identical interval. When the downcounter reaches zero, a strobe pulse is produced to enable the analog measuring circuits, allowing for precise sampling of the impulse being monitored.
