Abstract

1. Increased activities of serum enzymes were observed after application of DC countershock in 4 of 6 patients. The elevated levels of serum transaminases were found after countershock in 2 patients with serum hepatitis, especially GPT more elevated than GOT. 2. Using the indwelling catheter in three positions in canine experiments resulted in the assumption that the increased levels of plasma enzymes might be derived mainly from hepatic vein in 2 dogs, from coronary sinus in one dog and from superior vena cava in one dog. 3. It is suggested that a small rise of serum or plasma enzyme activities after application of DC countershock originates mainly from myocardium, from hepatic tissue and from skeletal muscle. 4. Atrial fibrillation recurred 2 weeks after reversion in one patient who had not received quinidine sulfate, while a sinue rhythm has persisted after reversion in another patient without administration of quinidine sulfate. 5 . The transient electrocardiographic changes after application of DC countershock were the following : atrial or ventricular premature beats, ventricular bigeminy, nodal rhythm, depressed or elevated ST segment and inverted T wave. The distinctly elevated ST segment immediately after application of DC counter-shock was concave facing upwards and returned to the isoelectric line 3 minutes later in one patient who showed simultaneous ventricular bigeminy. 6. Serum potassium values were increased after application of DC countershock in 2 of 4 measurements, while serum sodium value was decreased concurrently in one of them. 7. Cardiac output and stroke volume were increased after cardioversion in the cases measured.
