WebMay 25, 2024 · Cardiac sympathetic upregulation is one of the neurohormonal compensation mechanisms that play an important role in the pathogenesis of chronic heart failure (CHF). In the past decades, cardiac 123I-mIBG scintigraphy has been established as a feasible technique to evaluate the global and regional cardiac sympathetic innervation. … WebAdrenaline is normally produced by the adrenal glands and by a small number of neurons in the medulla oblongata. [11] It plays an essential role in the fight-or-flight response by increasing blood flow to muscles, heart output by acting on the SA node, [12] pupil dilation response, and blood sugar level.

Some patients did note palpitations, especially at the high doses of epinephrine (≥ 0.2 μg · kg −1 · min −1 ). Isolated premature ventricular extrasystoles occurred in 3 (7%) of 44 gene-negative patients, 4 (10%) of 40 LQT1 patients, 5 (17%) of 30 LQT2 patients and 0 (0%) of 11 LQT3 patients.
