Aim: To analyze electrocardiographic features of patients diagnosed with posttraumatic stress disorder (PTSD) after the Van-Ercis earthquake, with a shock measuring 7.2 on the Richter scale that took place in Turkey in October 2011. METHODS: Surface electrocardiograms of 12 patients with PTSD admitted to Van Ercis State Hospital (Van, Turkey) from February 2012 to May 2012 were examined. Psychiatric interviews of the sex and age matched control subjects, who had experienced the earthquake, confirmed the absence of any known diagnosable psychiatric conditions in the control group. RESULTS: A wide range of electrocardiogram (ECG) parameters, such as P-wave dispersion, QT dispersion, QT interval, Tpeak to Tend interval, intrinsicoid deflection durations and other traditional parameters were similar in both groups. There was no one with an abnormal P wave axis, short or long PR interval, long or short QT interval, negative T wave in lateral leads, abnormal T wave axis, abnormal left or right intrinsicoid deflection duration, low voltage, left bundle branch block, right bundle branch block, left posterior hemiblock, left or right axis deviation, left ventricular hypertrophy, right or left atrial enlargement and pathological q(Q) wave in either group. CONCLUSION: The study showed no direct effect of earthquake related PTSD on surface ECG in young patients. So, we propose that PTSD has no direct effect on surface ECG but may cause electrocardiographic changes indirectly by triggering atherosclerosis and/or contributing to the ongoing atherosclerotic process.

Objectives: We aimed to evaluate the shortand mid-term results of patients with atrial septal defect (ASD) who were treated with percutaneous closure. Study design: Seventy-nine patients with a diagnosis of secundum ASD (54 female and 25 male; mean age 26.2+/-17.2; range 3 to 71] years) were included in this study. All patients were evaluated by transthoracic (TTE) and/or transesophageal echocardiography (TEE). Amplatzer septal occluder (ASO) was used for percutaneous closure in all patients. In 76 patients, the procedure was performed under local anesthesia with TTE, while in the other 3 patients, it was performed with general anesthesia under the guidance of TEE. Patients were followed up at the 1st, 3rd, 6th and 12th months and annually thereafter. Mean followup period was 13.6+/-6.6 months. Results: Mean diameter of ASDs was 18.2+/-7.5 mm and stretched diameter was 20.7+/-8.04 mm during balloon dilatation, and mean diameter of implanted devices was 22.7+/-8.5 mm. Procedural time was 40.2+/-12.6, and fluoroscopy time was 10.9+/-4.1 minutes. The procedure was successfully performed in all patients (100%). One patient with cardiac tamponade died seven days after cardiac surgery. In two patients, the implanted devices embolized to the pulmonary circulation. Residual flow was found in three patients immediately after the procedure, without residual shunts one month after closure. Mild pericardial effusion in one patient and significant residual shunt due to device malposition in another were discovered at 1 and 6 months of the postprocedural follow- up period, respectively. Conclusion: Our findings showed that percutaneous closure of ASDs is successful in most patients with a low complication rate, and demonstrated that residual shunts do not develop in the majority of patients in the shortand mid- term.
