Background: Atrial AutoCapture™ (ACap™) was a new technological development that confirmed atrial capture by analyzing evoked response (ER) with a new method – paced depolarization integral ER detection – and optimized energy output to changes in the stimulation threshold.
The close relationship between TRPA1, TRPV4, and the existence of mechanical hyperalgesia in rats with KOA has been verified, yet whether TRPA1 and TRPV4 levels change according to rat mechanical stimulation threshold levels remained unclear.
He noted that, while ECT and TMS stimulate neurons in the brain to fire, tDCS changes the stimulation threshold without directly causing the neurons to discharge.

In our study, differences in ICD and PM groups in terms of stimulation threshold and impedance also hold true for LVEFF When groups are analysed separately, LVEF alone does not have significant effect on stimulation threshold and impedance.
The stimulation threshold was defined as the lowest current required to obtain clear evoked EMG.
Temporal patterns of stimulation for exercise and walking were defined by stimulation threshold, maximal pulse duration, and MMT.
The typical pacemaker stimulation signal level (about 3 volts) and duration (about 1 millisecond) are intentionally well above the stimulation threshold of most individuals in order to pace the heart and to provide reliable operation.
6) since bone is less conductive than the surrounding tissue, it may increase current densities in narrow regions of tissue between the bone and the skin, resulting in lower nerve stimulation thresholds than expected.
Both leads build on the established Corox family of heart failure leads, known for their reliability and high performance characteristics, including low stimulation thresholds and low rates of dislodgment.
