Langendorff heart

The Langendorff heart or isolated perfused heart assay is an ex vivo technique used in pharmacological and physiological research using animals and also humans. Named after the German physiologist Oskar Langendorff, this technique allows the examination of cardiac contractile strength and heart rate without the complications of an intact animal or human. After more than 100 years, this method is still being used.
