Pharmacological, Temperature, and Electrogram Studies on the Posterior Lymph Heart of the Bullfrog

In view of the discrepancies and conflicts produced by previous studies on amphibian lymph hearts, a study was initiated to reinvestigate the pharmacological, temperature, and electrical aspects of lymph heart physiology. Bullfrogs were chosen as the experimental animal, All lymph heart responses to experimentation were physiographically recorded as myograms and electrograms.
The results are in agreement with previous studies on some aspects and in conflict on others. From the results obtained, lymph heart muscle appears to possess both skeletal and cardiac muscle properties as evidenced by drug responses and reactions to temperature. The precise components of the electrogram remain unclear.
It is suggested that further investigation should be made to better determine the true nature of lymph hearts.
