I rarely use it (mostly for hypotensive atrial fibrillation). However, understanding phenylephrine is a prerequisite to understanding related vasopressors, particularly midodrine and norepinephrine. WebNov 20, 2024 · the effect of bradycardia on cardiac output is often underestimated. Bradycardia directly pulls down the cardiac output, potentially causing shock. Slowing down the heart rate may cause a minimal increase in diastolic filling, thereby increasing the stroke volume. However, this compensatory factor is weak and extremely limited. WebJan 13, 2024 · Dobutamine is a synthetic catecholamine. As well as a well-defined catechol group, it possesses a humongous amine substituent group, which confer upon it a high level of beta-1 selectivity. This is the result of "intelligent drug design".
