Key result
Tricyclic antidepressant poisoning caused a hyperkinetic circulation, with cardiac output twice as high as in hypnotic drug poisoning and a 40% lower arteriovenous oxygen difference.

Observational (n=17)
What are the cardiovascular hemodynamic effects of tricyclic antidepressant poisoning compared to hypnotic drug poisoning?
TCA poisoning induces a hyperkinetic circulatory state with increased cardiac output and widened QRS complexes, likely driven by adrenergic stimulation rather than myocardial insufficiency.
Curt Thorstrand (1974) conducted an observational in Poisoning by tricyclic antidepressants or hypnotic drugs (n=17). Tricyclic antidepressant poisoning vs. Hypnotic drug poisoning was evaluated on Cardiac output and cardiovascular dynamics. Tricyclic antidepressant poisoning caused a hyperkinetic circulation, with cardiac output twice as high as in hypnotic drug poisoning and a 40% lower arteriovenous oxygen difference.
