The normal frequency-force relationship of left guinea-pig atria can be largely suspended when strong beta-adrenergic stimulation by orciprenaline is antagonized by the negative inotropic effect of adenosine, so that contraction amplitude is nearly equal at an intermediate level over a wide range of stimulation rates. Curves obtained with new method for recording continuous frequency-force loops are presented.
当奥西那林引起的强烈β-肾上腺素能刺激被腺苷的负性肌力作用拮抗时，豚鼠左心房正常的频率-力关系可在很大程度上被消除，从而在很宽的刺激频率范围内，收缩幅度在中间水平几乎相等。本文展示了用记录连续频率-力环的新方法所获得的曲线。
