Research paper thumbnail of Ventriculatrial Block During Atrioventricular Nodal Reentrant Tachycardia Suggesting Existence of an Upper Common Pathway

Although a "final common pathway" connecting the slow and fast pathways to the proximal His bundle was thought to be part of the reentrant circuit, debate on the presence of an upper common pathway continues. We report a case of AVNRT continuing despite the occurrence of ventriculoatrial block, thus supporting the existence of an upper common pathway.

Research paper thumbnail of Left Ventricular Apical Aneurysm as a Consequence of Diffuse Type Congenital Nonfamilial Supravalvular Aortic Stenosis in a 30-Year-old Female

We present a 30-year-old woman with diffuse SVAS complicated with left ventricular apical aneurysm. We believe that subtle left ventricular myocardial ischemia or infarction and long-lasting severe pressure overload to the apical chamber caused LV apical aneurysm in our case. Acquired LV apical aneurysm secondary to supravalvular aortic stenosis, in the absence of atherosclerotic coronary artery disease and hypertrophic obstructive cardiomyopathy, has not been described before.

Research paper thumbnail of The signal-averaged P-wave duration is longer in hypertensive patients with history of paroxysmal atrial fibrillation as compared to those without

Therefore, it is important to assess non-invasively the risk of developing paroxysmal atrial fibrillation (PAF) in hypertensive patients during sinus rhythm. This study was undertaken to determine if hypertensive patients with history of PAF could be identified while in sinus rhythm by measurement of signal-averaged ECG P-wave duration. Methods: Signal-averaged electrocardiography (SAECG) P-wave recording was performed in 44 hypertensive patients (30 men and 14 women; mean age 60F11 years, group A) who had a history of paroxysmal AF and in 50 hypertensive patients without history of AF (33 men and 17 women; mean age 57F12, group B). All patients were also evaluated by using echocardiography to measure left ventricular ejection fraction (LVEF) and left atrial diameter (LAD). Results: SAECG P-wave duration was found to be significantly higher in group A than in group B (146F14 ms vs. 128F11 ms, pb0.001). Left atrial diameter was not significantly different (40.1F3.4 mm vs. 39.3F3.0 mm, pN0.05), whereas LVEF was significantly lower in group A than group B (63F5% vs. 67F4%, p=0.03). There was a correlation between SAECG P-wave duration and age (r=0.32, pb0.05). In univariate analysis, SAECG P-wave duration and LVEF were significant predictors of PAF, but only SAECG P-wave duration remained a significant independent predictor of PAF in multivariate analysis. Conclusion: The results of this study indicate that hypertensive patients with history of PAF can be detected while in sinus rhythm by signalaveraged ECG P-wave duration.

In this study, we evaluated whether echocardiographic SAT is related to insulin resistance and IMT in obese children. A total of 46 obese subjects (10.2+/-2.5 years of age, 25 male patients) and 30 age- and gender-matched lean subjects (10.8+/-3.1 years of age, 13 male patients) were included in this study. The criterion for diagnosing obesity was defined as the body mass index (BMI) being over 97% percentile of the same gender and age. Serum triglyceride (TG), low- and high-density lipoprotein, cholesterol, glucose and insulin levels were measured during the fasting state. Each subject underwent a transthoracic echocardiogram and the SAT thickness was measured during end-diastole from the parasternal long-axis views. The obese subjects had significantly higher SAT thickness and IMT values compared with the subjects in t...

Patients and methods: The study included 48 FMF patients (26 males, 22 females, mean age 11.10±3.42 years; range 5 to 18 years) as the FMF patients and 31 healthy children (17 males, 14 females, mean age 9.61±2.83 years; range 5 to 17 years) as the healthy controls. Electrocardiography and conventional echocardiography were performed on the FMF patients and healthy controls. Both groups were evaluated with a standard 12-lead electrocardiography. QT, JT and RR distances were measured in both groups. The corrected QT (QTc) and corrected JT (JTc) were calculated. QTcd and corrected JT dispersion (JTcd) were detected. Results: There was no statistically significant difference between the FMF patients and healthy controls in terms of RR, QT, QTd, QTcd, JT, JTc, JTd, and JTcd measurements and echocardiography parameters. QTc value was higher in the FMF patients than the healthy controls. Conclusion: QTc value indicates increased ventricular sensitivity and is an important marker of cardiovascular mortality. It has an important effect on sudden cardiac death and arrhythmia. Our study results suggest that electrocardiographic monitoring may be useful in patients with FMF.

QT intervalindeki uzama doğumsal olabildiği gibi, ilaç kullanımı ve elektrolit bozuklukları gibi nedenlere bağlı olarak da gelişebilir. Elektrolit bozukluğu sonucu gelişen "torsades de pointes"nin kronik hipokalsemi, hipokalemi, hipomagnezemi nedeniyle oluştuğu bildirilmektedir. Çocukluk çağında hızlı başlangıçlı ani gelişen izole hipokalemiye bağlı "torsades de pointes" olgusu literatürde bildirilmemiştir. Bu yazıda akut miyeloblastik lösemili bir çocukta ağır pnömoni zemininde ani başlayan, izole hipokalemi sonucu gelişen ve hızlı potasyum replasman tedavisi ile düzelen "torsades de pointes" olgusu sunulmaktadır.
