Native records of contractile activity of the left ventricle of isolated rat<unk>  perfused under<unk>  technique. Curve A - contractile function of the<unk>  is greatly depressed after ischemia-reperfusion. Curve B - a set of short ischemic episodes (ischemic preconditioning) before prolonged ischemia provides functional recovery of contractile activity of the<unk>  at reperfusion. The<unk>  or isolated perfused<unk>  assay is an ex vivo technique used in pharmacological and physiological research using animals and also humans. It allows the examination of cardiac contractile strength and<unk>  rate without the complications of an intact animal or human. After 90 years this method is still being used.
