In the article by Zipes, “Sudden Cardiac Arrest and Death Following Application of Shocks From a TASER Electronic Control Device,” which was published in the May 22, 2012 issue of the journal (Circulation. 2012;125:2417–2422), two points are in error.
First, where it is stated that “Individuals were previously clinically healthy males …” it was meant that they were clinically healthy from a cardiovascular standpoint without manifest cardiovascular symptoms. As indicated in the table of the original manuscript, autopsy may have shown underlying cardiac disease not clinically manifest. Four were inebriated, as indicated by the drug screen (table), with a history of alcohol abuse; case 3 had an attention deficit disorder, possibly bipolar; case 5 was mentally confused, perhaps due to a post ictal state after a seizure; and case 6 was agitated with a diagnosis of depressive disorder, schizophrenia and medication noncompliance. Second, the first available ECG shown in the figure was a representative ECG strip chosen from those recorded at the time of attempted resuscitation and was not the very first ECG recorded in all cases. Upon comparison of these tracings, there is no material difference in the recorded rhythms. None of these statements change the author's opinion expressed in the conclusion of the article but are presented for completeness and accuracy.
