x The aim of this study was to investigate changes in Nogo receptor 1 (NgR1 ) expression in the cerebrum after cardiopulmonary resuscitation (CPR) in rats. Cardiac arrest was induced by alternating current in 50 SD rats through transcutaneous electrical epicardium stimulation, and CPR was performed with the Utstein mode 6 minutes after cardiac arrest. Rats were killed 1, 3, and 7 days after CPR. We performed immunofluorescence with antibodies against NgR1 to map the distribution of NgR1 in the rat cerebrum, whereas quantitative polymerase chain reaction was performed for quantitative analysis of NgR1 messenger RNA (mRNA).

x Yamashina et al [1] present an interesting observation of coronary spasm-induced ventricular fibrillation (VF) encountered during therapeutic hypothermia. Unlike the electrocardiogram (ECG) recorded after the initial prehospital cardiac arrest, repeat ECG following resuscitation from the in-hospital cardiac arrest during therapeutic hypothermia revealed hypothermic changes. The author's Fig. 3 demonstrated high amplitude Osborn waves (evident in the lateral leads V4 , V5 , V6 , and lead I), sinus bradycardia, rate 35 beats/minute, prolonged PR interval, widened QRS complex, and a baseline with possible shivering artifacts.

x This study evaluated the energy requirements for porous electrodes implanted on the parietal pericardium versus those for porous electrodes implanted on the epicardial surface of the heart. Defibrillation with a 2.5-cm porous electrode implanted on the parietal pericardium was successful in 42% of all episodes of ventricular fibrillation. The minimal energy requirement ranged from 30–68 J, with an average of 46 J. Epicardial defibrillation was successful in approximately 80% of all episodes. The average maximal energy was 21.3 J.

x Brugada syndrome is characterized by the electrocardiographic (ECG) pattern of right bundle-branch block (RBBB) with a high take-off, coved ST-segment elevation in the precordial leads V1 to V3 , and the risk of sudden cardiac death [1]. Typically, there is no evidence of structural heart disease. In many cases, Brugada syndrome has been linked to a mutation of the gene SCN5A, which encodes for the fast cardiac sodium channel. In patients with the Brugada syndrome, pharmacologic sodium channel blockade can increase the degree of ST-segment elevation [2].

x We read with great interest the recently published article by Bischof and coworkers entitled with ‘ST depression in lead aVL differentiates inferior ST-elevation myocardial infarction from pericarditis’ [1]. The authors sought to determine if the presence of any ST-segment depression in lead aVL would differentiate inferior ST segment elevation myocardial infarction (STEMI) from pericarditis. This study consists of retrospective study of 3 populations. Cohort 1 included patients coded as inferior STEMI, cohort 2 included patients with pericarditis.

x Cardiopulmonary resuscitation (CPR) is a well-recognized means of CPR maintaining circulation during cardiac arrest. However, CPR can cause a variety of complications even when performed properly. Documented complications of standard CPR include rib fractures, sternal fractures, pneumothorax, and rarely cardiac, gastric, or hepatic complications.1-3 Cardiac tamponade caused by CPR is rare and is most often caused by fractures of the ribs or sternum.

x The genetic nature of Brugada syndrome has been well reported, with the causative factor being a mutation in the gene encoding cardiac sodium ion channels. Yet, although Brugada syndrome requires specific conditions to be satisfied, a Brugada pattern on electrocardiogram (ECG) has been reported in numerous situations. We describe a typical Brugada-type picture in a previously healthy man, with no cardiac history or risk factors, who presented after a substantial overdose of flecainide. This suggests that a severe overdose of flecainide can sufficiently suppress cardiac sodium ion channels, triggering a Brugada-type pattern in patients without the hereditary form.

x Acute myocardial infarction (AMI) is a not uncommon diagnosis in the emergency department. During ST-segment elevation AMI (STEMI), the electrocardiogram (ECG) typically follows a progression of abnormality, beginning with hyperacute T waves and culminating with ST-segment elevation; pathologic Q waves can appear early and/or late in the process. Other findings include T-wave inversion and ST-segment depression which can occur before, during, or after the STEMI event. The evolution of ECG through these changes can occur rapidly after coronary artery occlusion.
