カルシウムの房室刺戟傅達時間並に心室收縮時間に及ぼす影響に就て

抄録

The present author examine the effect of calcium on the atrioventricular conduction time and ventricular contraction time by applying Takahashi's and Fridericia's formulae in relation to the timely change of the production of stimuli and drew the following conclusion. That is, the atrioventricular conduction time was slightly elongated from immediately to 10〜20 minutes after the injection iu the greater majority of cases. The ventricular contraction time was markedly shortened from immediately to more than 80 minutes after injection with calcium.
