[Changes in the ECG telemetry of lambs infected with Cysticercus ovis]

Six lambs were experimentally infected with Cysticercus ovis. Some changes were followed up in the ECG by means of the radiotelemetric method. The infection process led to the following more important changes, such as sinus tachicardia and arhythmia, auricular fibrilation, sinoauricular block, atrial dissociation, the incidence of a pathologic Q deflection; lowering of the R deflection amplitude, and inversion of the T wave. It was found that the changes referred to persist for a longer period (in the case of infarction), and could be made use of in dispensary studies.
