    ABSTRACT: A 34-year-old female patient was admitted with the complaints of inability to stand upright, palpitations, dizziness, and fatigue in the upright posture for the last one year. She was found to stand upright for less than one minute without symptoms. Tilt table testing showed that, compared to baseline her heart rate increased 55 beats/min in the fifth minute of the test with the symptoms of palpitations, fatigue and sweating without any significant change in her blood pressure. Postural orthostatic tachycardia syndrome was diagnosed, and pyridostigmine treatment was started. Four months after treatment her symptoms were relieved so that she was able to function as a nurse.

    ABSTRACT: With constantly evolving technology and an ever-increasing number of patients with pacemakers, clinicians will encounter various pacemaker malfunctions in their practice. While some of these issues can be solved even by using only the pacemaker׳s mode settings, others require re-intervention; neglecting a pacemaker׳s malfunction without full investigation threatens the patient׳s life. In this report, we describe a patient with a dual-chamber pacemaker with neglected or unresolved dyssynchronization that occurred 2 years after implantation.

    ABSTRACT: Recent studies have reported that a novel cardiac biomarker, heart-type fatty acid-binding protein (h-FABP), significantly predicts mortality inpatients with pulmonary embolism (PE) at intermediate risk. The aim of this study was to evaluate the effect of thrombolytic therapy on prognosis of the intermediate risk acute PE patients with elevated levels of h-FABP. This is non-interventional, prospective, and single-center cohort study where 80 patients (mean age 62 ± 17 years, 32 men) with confirmed acute PE were included. Only patients with PE at intermediate risk (echocardiographic signs of right ventricular overload but without evidence for hypotension or shock) were included in the study. h-FABP and other biomarkers were measured upon admission to the emergency department. Thrombolytic (Thrl) therapy was administered at the physician's discretion. Of the included 80 patients, 24 were h-FABP positive (30 %). 14 patients (58 %) with positive h-FABP had clinical deterioration during the hospital course and required inotropic support and 12 of these patients died. However, of 56 patients with negative test, only 7 patients worsened or needed inotropic support and five patients died during the hospital stay. Mortality of patients with PE at intermediate risk was 21 %. The 30-day mortality rate was significantly higher in h-FABP(+) patients compared to h-FABP(-) patients (9 vs. 50 %, p < 0.001). Multivariate analysis revealed h-FABP as the only 30 day mortality predictor (HR 7.81, CI 1.59-38.34, p = 0.01). However, thrl therapy did dot affect the survival of these high-risk patients. Despite, h-FABP was successful to predict 30-days mortality in patients with PE at intermediate risk; it is suggested to be failed in determining the patients who will benefit from thrl therapy.

    ABSTRACT: PURPOSE: Heart-type fatty acid binding protein (H-FABP) is a sensitive marker of myocardial injury and predictor of worse prognosis in patients with pulmonary embolism (PE). Assessment of right ventricular dysfunction and pulmonary artery obstruction index (PAOI) with computed tomography (CT) has been reported as a predictor of mortality in PE. Therefore, we aimed to assess the correlation between H-FABP and CT angiographic PAOI in PE patients at intermediate risk. MATERIALS AND METHODS: Sixty-one patients (28 males; mean age, 62±17 years) with diagnosis of PE were included in this study. CT was performed in all patients, and the following parameters were evaluated: right ventricle/left ventricle ratio (RV/LV), pulmonary artery axial diameter, superior vena cava axial diameter, and PAOI determined with Qanadli score. Blood samples were assessed for H-FABP and troponin levels. Patients were followed for 30 days after discharge. RESULTS: Mean PAOI was 57±18%. Eleven patients died during the follow-up period due to PE (18% mortality rate). H-FABP was positive in 21 patients (35%). There was no difference in CT parameters between patients with positive H-FABP and negative H-FABP. In addition, CT parameters were similar between patients who survived and those who did not. RV/LV ratio correlated with PAOI score. Among the biomarkers, troponin levels correlated with both RV/LV ratio and PAOI. H-FABP was an independent predictor of mortality. PAOI and RV/LV ratio did not predict 30-day mortality. CONCLUSION: Although H-FABP positivity confers a bad prognosis on PE patients at intermediate risk, PAOI did not predict mortality in this group.

    ABSTRACT: Organophosphate pesticides have emerged as a common cause of poisoning, particularly in developing countries. The most common electrocardiographic abnormalities observed in organophosphate poisoning are sinus tachycardia, QT interval prolongation, and, very rarely, ventricular arrhythmias. We report a case of organophosphate poisoning associated with atrial fibrillation, right bundle branch block, QT interval prolongation, and intermittent narrow QRS complexes that were most likely due to automaticity from the region of the left posterior fascicle.

    ABSTRACT: In this study, our aim was to evaluate the effect of a higher dose of atorvastatin on the recurrence rate of atrial fibrillation (AF) after electrical cardioversion (EC) in addition to antiarrhythmic therapy. 48 patients with persistent AF were included in this study. The patients were randomized to an atorvastatin 40-mg treatment group and a control group. Atorvastatin was started 3 weeks before EC and was continued for 2 months after EC. EC was performed using biphasic shocks after 3 weeks of treatment with the orally administered anticoagulant warfarin. Lipid and inflammatory parameters (high-sensitivity C-reactive protein, white blood cell count and fibrinogen level) were evaluated at the baseline and before EC. The endpoint of this study was electrocardiographically confirmed recurrence of AF of >10 min. There were no significant differences in baseline characteristics and lipid and inflammatory marker levels between the treatment and control groups. Total cholesterol and low-density lipoprotein levels were significantly decreased in patients taking atorvastatin for 2 months compared with baseline values (174 ± 31 vs. 129 ± 25 mg/dl, p = 0.001, and 112 ± 23 vs. 62 ± 20 mg/dl, p = 0.001, respectively), while no significant change occurred in control patients (168 ± 26 vs. 182 ± 29 mg/dl, p = 0.07, and 99 ± 18 vs. 108 ± 26 mg/dl, p = 0.1, respectively). At the end of the 2-month follow-up period, 9 patients (20.5%) experienced AF recurrence, and there was no significant difference in AF recurrence rate between the treatment and control groups (26 vs. 13%; p = 0.2). Atorvastatin therapy prior to EC does not prevent the recurrence of arrhythmia in patients with persistent AF who are receiving antiarrhythmic therapy.

    ABSTRACT: Radiofrequency ablation of atrial flutter is a commonly performed procedure. Ablation success depends upon complete transmural atrial tissue injury to achieve bidirectional cavotricuspid isthmus (CTI) block. Transmural ablation increases risk of injury to the adjacent right coronary artery (RCA). Distance between the RCA and the endocardium within the CTI area is not well described. We aimed to perform in vivo measurements of the distance between the CTI area and adjacent RCA. Thirty-three consecutive patients underwent electrocardiogram-gated contrast-enhanced computed tomography. CTI area was divided into nine segments based on three common catheter locations (paraseptal, central, and lateral or 5, 6, and 7 o'clock) and ventricular to atrial ablation line. Mean age was 64 ± 11 years and 97% of the participants were male. Paraseptal, central, and lateral measurements at the tricuspid annulus ridge showed endocardial to RCA distance 9 ± 3, 6 ± 2, and 5 ± 3 mm, respectively (range 2-17 mm). Corresponding measurements for the ventricular side were 5 ± 3, 4 ± 2, and 4 ± 2 mm and atrial side measurements were 3 ± 2, 3 ± 2, and 3 ± 3 mm. Distance was ≤2 mm in 14% of segments on the ventricular side and 39% of segments on the atrial side. Paired t-test showed significant difference (P < 0.001) between tricuspid annulus ridge measurements and adjacent atrial or ventricular measurements. Distance between endocardium and RCA lumen is reduced in areas adjacent to the tricuspid annulus ridge.

    ABSTRACT: Sudden cardiac arrest is one of the leading causes of death in patients with heart failure (HF). The implantable cardioverter-defibrillator (ICD) is the only evidence-based treatment strategy for patients who have survived a life-threatening ventricular arrhythmic event. Randomized clinical trials have shown that specific subsets of HF patients with ischemic and nonischemic dilated cardiomyopathy benefit from ICD therapy for primary prevention of sudden cardiac arrest. Cardiac resynchronization therapy has become the device-based therapy of choice for improving symptoms and survival in severe HF patients with evidence of ventricular dyssynchrony. This review summarizes the current status of ICD therapy in treating HF patients based on randomized clinical trials and current practice guidelines.

    ABSTRACT: In patients with atrial fibrillation (AF) and atrial flutter (AFL), the value of the 12-lead surface electrocardiogram (ECG) in predicting direct current cardioversion (DCCV) outcomes has not been thoroughly investigated. We sought to determine whether the type of atrial arrhythmia (AF versus AFL) and the characteristics of the atrial fibrillatory waves (fine versus coarse) on the surface ECG would help predict post DCCV outcomes. A total of 76 consecutive patients undergoing elective DCCV for persistent AF or AFL at the Minneapolis Veterans Affairs Medical Center were included in this retrospective cohort study. All patients had ECGs immediately and one month after DCCV. Mean age was 67+/-8 years and 97% of the participants were male. DCCV was immediately successful in 64 (84%) patients. Of these, 35 (46%) remained in sinus rhythm at one month. DCCV was immediately successful in all patients (N 13) with fine AF versus 34/45 of those with coarse AF (P 0.05). Patients with fine AF were also more likely to remain in sinus rhythm at one-month follow up compared to those with coarse AF (8/13 versus 13/45; P 0.03). Also, at one-month follow up, the patients with AFL were more likely to maintain sinus rhythm than those with AF (14/18 of AFL versus 21/58 of AF; P 0.003). The characteristics of the fibrillatory waves on surface ECG should be utilized to determine the success after DCCV in patients with AF and AFL.

    ABSTRACT: Syncope is a syndrome characterized by a relatively sudden, temporary and self-terminating loss of consciousness; the causes may vary, but they have in common a temporary inadequacy of cerebral nutrient flow, usually due to a fall in systemic arterial pressure. However, while syncope is a common problem, it is only one explanation for episodic transient loss of consciousness (TLOC). Consequently, diagnostic evaluation should start with a broad consideration of real or seemingly real TLOC. Among those patients in whom TLOC is deemed to be due to ''true syncope'', the focus may then reasonably turn to assessing the various possible causes; in this regard, the neurally-mediated syncope syndromes are among the most frequently encountered. There are three common variations: vasovagal syncope (often termed the ''common'' faint), carotid sinus syndrome, and the so-called ''situational faints''. Defining whether the cause is due to a neurally-mediated reflex relies heavily on careful history taking and selected testing (e.g., tilt-test, carotid massage). These steps are important. Despite the fact that neurally-mediated faints are usually relatively benign from a mortality perspective, they are nevertheless only infrequently an isolated event; neurally-mediated syncope tends to recur, and physical injury resulting from falls or accidents, diminished quality-of-life, and possible restriction from employment or avocation are real concerns. Consequently, defining the specific form and developing an effective treatment strategy are crucial. In every case the goal should be to determine the cause of syncope with sufficient confidence to provide patients and family members with a reliable assessment of prognosis, recurrence risk, and treatment options.
