Öğe Asymptomatic left ventricular myxoma diagnosed incidentally by transthoracic echocardiography(2005) Bicer A.; Turhan H.; Cagrici G.; Yasar A.S.; Sasmaz H.[No abstract available]Öğe The impact of cardiorespiratory fitness on inflammatory markers in patients with metabolic syndrome(2006) Turhan H.; Yetkin O.[No abstract available]Öğe Increased P-wave duration and P-wave dispersion in patients with aortic stenosis(Turkish Anaesthesiology and Intensive Care Society, 2002) Turhan H.; Yetkin E.; Şenen K.; Ileri M.; Atak R.; Biçer A.; Şaşmaz H.P-wave dispersion (PWD), defined as the difference between maximum and minimum P-wave duration, has been reported as being useful for the prediction of paroxysmal atrial fibrillation (AF). AF is the most common arrhythmia and an important prognostic indicator for clinical deterioration in patients with aortic stenosis (AS). The aim of the present study was to evaluate PWD in patients with AS. The study population consisted of two groups: Group I consisted of 98 patients with degenerative AS (76 men, 22 women; aged 63±8 years) and group II consisted of 98 age and sex matched healthy subjects without any cardiovascular disease. Twelve-lead electrocardiogram was recorded for each subject. The P-wave duration was calculated in all leads of the surface electrocardiogram. The difference between the maximum and minimum P-wave duration was calculated and this difference was defined as PWD. All patients and control subjects were also evaluated by echocardiography to measure the left atrial diameter, left ventricular ejection fraction, left ventricular wall thicknesses, maximum and mean aortic gradients. Patients were also evaluated for the presence of documented paroxysmal AF. Maximum P-wave duration (126 ms) and PWD of group I were found to be significantly higher than those of group II (108 ms). In addition, patients with paroxysmal AF (130 ms) had significantly higher PWD (121 ms) than those without paroxysmal AF. There was no significant difference between two groups regarding minimum P-wave duration. There was no significant correlation between echocardiographic variables and PWD. PWD, indicating increased risk for paroxysmal AF, was found to be significantly higher in patients with AS than in those without it. Further assessment of the clinical utility of PWD for the prediction of paroxysmal AF in patients with severe AS will require longer prospective studies.Öğe Relationship between myocardial viability and the predischarge electrocardiographic pattern in patients with first anterior wall acute myocardial infarction(2003) Atak R.; Turhan H.; Senen K.; Ileri M.; Yetkin E.; Ozbakir C.; Demirkan D.Background: The assessment of residual viability in the infarcted area after an acute myocardial infarction is relevant to subsequent management and prognosis. Objective: The aim of this study was to investigate the correlation between myocardial viability after an acute anterior myocardial infarction (AMI) as assessed by low dose dobutamine stress echocardiography (LDDSE) and the electrocardiographic patterns of ST segment and T wave abnormalities at the end of the first week of the acute event. Methods: Sixty-nine consecutive patients (51 men, 18 women, mean age±standard deviation=57±11 years) who admitted to our clinic due to a first episode of transmural AMI were included in this study. Two-dimensional echocardiography was performed to all patients during rest and low dose dobutamine administration at the end of the first week of admission (7±2 days). Patients were classified into four groups according to ST segment and T wave morphology: group A, ST elevation ?0.1 mV and negative T waves; group B, ST elevation ?0.1 mV and positive T waves; group C, ST elevation ?0.1 mV and negative T waves and group D, ST elevation ?0.1 mV and positive T waves. Results: Myocardial viability was detected more often in patients with isoelectric ST segments (22/24, 92%) than those with elevated ST segments (21/45, 47%) (P<0.001). Similarly patients with negative T waves had myocardial viability more frequently compared to those with positive T waves (32/45, 71% vs. 11/24, 46%, P<0.01). Seventeen (94%) of 18 patients in group A and 5 (83%) of six patients in group B had viable myocardium (P>0.05). Myocardial viability was found in 15 (56%) of 27 patients in group C and six (33%) of 18 patients in group D (P<0.01). As a marker of viable myocardium, isoelectricity of ST segment was specific (92%) but only moderately sensitive (51%), with a 92% positive predictive accuracy and a poor (53%) negative predictive value. T wave negativity was less spesific but more sensitive than isoelectricity of ST segment for myocardial viability. Conclusion: The presence of isoelectric ST segment and negative T wave indicates a high probability of myocardial viablitiy. However, absence of these electrocardiographic patterns does not exclude the presence of viable myocardium. © 2003 Elsevier Ireland Ltd.

Slow flow phenomenon in epicardial coronary arteries is not infrequent finding during routine coronary angiography. However, the clinical features of patients with slow flow phenomenon have not been extensively studied. ST elevation in leads without Q waves during exercise testing has not been previously reported in patients with slow flow phenomenon. In the current case, we report a 29-year-old man with angiographically normal coronary arteries associated with slow coronary flow in the absence of any significant obstructive coronary artery disease and no evidence of epicardial coronary artery spasm in whom ST segment elevation in leads I and aVL was observed at maximal exercise of treadmill test. © 2006 Elsevier Ireland Ltd.
