Trans-2,3-enoyl-CoA reductase-like-related catecholaminergic polymorphic ventricular tachycardia with regular ventricular tachycardia and response to flecainide.

Introduction: We describe a unique case of TECRL-CPVT presented with cardiac arrest.

Methods: Post resuscitation, the patient developed regular ventricular tachycardia featuring a left purkinje system morphology.

Results: There was clear suppression of arrhythmia with the addition of flecainide and isolated ventricular ectopy causing secondary T-wave changes.

Assessment of the current knowledge and willingness to conduct medical research work of future healthcare providers: A cross-sectional study in Jeddah, Saudi Arabia.

Background And Objectives: Healthcare research work contributes significantly to the advancement and development of medical education. Numerous studies have demonstrated the efficiency and productivity of student participation in medical research work, which has a positive impact on the health system. In this study, we intended to examine medical students' knowledge and attitudes regarding, and actual participation in, medical research work.

Outcome after implantable cardioverter-defibrillator in patients with Brugada syndrome: the Gulf Brugada syndrome registry.

Background And Objective: Among patients with Brugada syndrome (BS) and aborted cardiac arrest, syncope, or inducible ventricular fibrillation at electrophysiologic study (EPS), the only currently recommended therapy is an implantable cardioverter-defibrillator (ICD), but these are not without complications. We assessed the total number of shocks (appropriate and inappropriate) and complications related to ICD in patients with BS.

Methods And Results: Twenty-five patients implanted with ICD for BS in 6 Gulf centers between January 1, 2002, and December 31, 2010, were reviewed.

Atrioventricular Nodal Re-entrant Tachycardia Ablation: Unusual Function of Slow Pathway.

Slow pathway (SP) ablation is an acceptable, standard method for atrioventricular nodal re-entrant tachycardia (AVNRT) ablation. The exact role of SP in the human heart and the possible negative implications of SP ablation are unknown. The current case report describes an unusual, brief, functional heart block, following radiofrequency ablation of the SP.

Automatic implantable cardioverter defibrillator for the treatment of ventricular fibrillation following coronary artery spasm: a case report.

Coronary artery spasm is an infrequently recognized condition that causes Prinzmetal's angina and specific electrocardiographic changes. A 50-year-old man who suffered a spontaneously aborted acute inferior myocardial infarction is presented. He underwent cardiac catheterization, which initially showed a normal coronary artery.

Predictive accuracy of tissue Doppler imaging for assessment of noninfarct myocardial region in patients with acute myocardial infarction.

Objectives: To investigate the value of pulsed tissue Doppler imaging (TDI) in order to predict significant coronary artery stenosis supplying the noninfarct region in patients after acute anterior myocardial infarction.

Subjects And Methods: Transthoracic echocardiography and coronary angiography were performed on 220 patients with acute anterior myocardial infarction. The TDI-derived variables of the mitral valve annulus in the noninfarct region, systolic velocity (Sm), early diastolic velocity (Em) and late diastolic velocity (Am), were estimated in centimeters per second, and the Em/Am ratio was calculated.

Successful implantation of a permanent pacemaker through a persistent left superior vena cava.

We present a case of successful implantation of a permanent pacemaker through an unusual course of a persistent left superior vena cava (PLSVC). A young male patient presented with symptomatic bradycardia and a heart rate of 35 beats per minute. The pacing lead was introduced through the standard left subclavian vein approach and was found to pass through an unusual course that was suspected to be a PLSVC.
