External sources, either within or outside the hospital environment, may interfere with the appropriate function of pacemakers which are being implanted all around the world in current medical practice. The patient and the physician who is responsible for follow-up of the pacing systems may be confronted with some specific problems regarding the various(More)
A previously healthy 31-year-old man with a history of smoking presented with severe prolonged chest pain for more than one hour duration. ECG taken on admission revealed slightly widened QRS complexes, and ST segment elevations in leads aVR, aVL, V 1 and V 2 in contrast to up-sloping ST-segment depressions in leads D II , D III , aVF and V 3–6 at the J(More)
BACKGROUND Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are inflammatory markers used as prognostic factors in various diseases. The aims of this study were to compare the PLR and the NLR of heart failure (HF) patients with those of age-sex matched controls, to evaluate the predictive value of those markers in detecting HF,(More)
Exercise-induced ST segment elevation without Q wave formation is rarely observed. Frequent causes are significant coronary stenosis, myocardial bridge and coronary vasospasm. Both exercise-induced ST segment elevation due to slow coronary flow and ST segment elevation in the recovery phase of the exercise stress test are very rare. We present a 49-year-old(More)
Takotsubo cardiomyopathy (TC) is a rare and usually physical or emotional stress-induced clinical disorder characterized by transient left ventricular dysfunction and apical segment ballooning. Much is still unknown regarding risk factors and clinical relationships. Recently, an association between TC and malignancies has been proposed. We present a case of(More)
The present case report describes a patient with dual chamber pacemaker whose surface ECG demonstrated paced right bundle branch block pattern suggesting a malpositioned ventricular lead in the left ventricle. However, diagnostic work-up revealed that the lead was appropriately located in the right ventricular apex. Diagnostic maneuvers and clues for(More)
