Article
Experimental and clinical study of catecholamine—induced hypokalemia in acute myocardial infarction
Adrenaline infusion to 8 rabbits led to remarkable dose-dependent hypokalemia. 2 of them died of ventricular arrhythmia (VA) with severe hypokalemia. In 6 rabbits with i.v. propranolol beforehand, no hypokalem...

Article
Effects of isoprenaline, phenylephrine on heart and influence of nifedipine on these effects
In a perfused isovolumetrically contracting rat heart model, the effects of isoprenaline (IPN) and phenylephrine (PE) on myocardial contraction and relaxation were investigated, and the influence of nifedipine...
