Effect of 1st & 2nd Stannius ligature on frog's heart

This experimental physiology practical is performed to prove excitability, autorhythmicity, conductivity & contractility properties of cardiac muscle. Video explains in detail about the procedure & interpretation of the graph. This video was recorded about 20 years back when the PG students used to perform these practicals as a part of their physiology curriculum.
