He was found to have a brain mass with bleeding, causing herniation of the brain stem.</span><span style="font-family: Arial, sans-serif; line-height: 1.538em;">&nbsp;</span></p><p class="MsoNormal"><span style="font-family: 'Arial','sans-serif';">Osborn waves are caused by hypothermia, and also by a number of other conditions. &nbsp;They are best described as an “extra” wave at the J point (junction of the QRS complex and ST segment).&nbsp; They are sometimes called “camel hump waves”.&nbsp; Hypothermia can also cause many other cardiac problems, including prolongation of the PR interval and QT interval, arrhythmias, and eventually asystole.</span></p><p class="MsoNormal"><span style="font-family: Arial, sans-serif; line-height: 1.538em;">In this case, the hypothermia was probably caused or exacerbated by the patient’s loss of thermoregulation due to the brain bleed. &nbsp;Neurological insults such as subarachnoid hemorrhage, and head trauma can cause Osborn waves, and this patient certainly was in that category, along with being demonstrably hypothermic. &nbsp;Other causes of Osborn waves include hypercalcemia, some medications, and as a normal variant.&nbsp;</span></p></div></div></div> Thu, 20 Mar 2014 16:31:14 +0000 Dawn 562 at https://www.ecgguru.com Jason's Blog: ECG Challenge of the Week for Sept. 16-23.
