The Effects of Ivabradine on Left Ventricular Synchronization and Tei Index in Patients with Systolic Heart Failure.

Background: The aim of our study was to evaluate in stable outpatients with systolic heart failure (HF) the 3 months effect of ivabradine on LV synchronization and Tei index in stable outpatients with systolic HF.

Methods: We evaluated prospectively 40 (30 males, 10 females) patients with HF. All patients were evaluated before and after treatment by transthoracic M mode, two dimensional (2D), pulsed-wave (PW), continuous wave (CW), color flow and tissue Doppler imaging (TDI) and tissue synchronization imaging (TSI).

Electrophysiological validation of total atrial conduction time measurement by tissue doppler echocardiography according to age and sex in healthy adults.

Background: We sought to validate total atrial conduction time (TACT) measurement via tissue Doppler imaging (TDI) by comparing the electrophysiological study (EPS) measurements of healthy subjects, according to age and sex.

Methods: Eighty patients with normal EPS results were included. TACT was measured by EPS and TDI.

The effects of ivabradine on left atrial electromechanical function in patients with systolic heart failure.

Aim: Heart rate (HR) reduction with ivabradine improves left ventricle filling by the prolongation of the diastolic time and increases stroke volume. But, it remains unclear what ivabradine's effect is on atrial conduction time and atrial mechanical functions. The aim of our study was to evaluate in stable outpatients with systolic heart failure (HF) the 3 months effect of ivabradine on atrial conduction time and mechanical functions.

Detection of atrial electromechanical dysfunction in obesity.

Introduction: Obesity is associated with atrial fibrillation and is known as an independent risk factor. The aim of our study was to investigate if there was any association between the body mass index and atrial electromechanical intervals in obese and non-obese patients.

Methods: Seventy patients were enrolled in the study.

Association of fragmented QRS complex with myocardial reperfusion in acute ST-elevated myocardial infarction.

In this study, we aimed to evaluate the relationship between TIMI myocardial perfusion (TMP) grade, as an indicator of myocardial reperfusion, and fragmented QRS (fQRS) in standard 12-lead electrocardiogram. Also, we evaluate fQRS is an additional indicator of myocardial reperfusion. One hundred patients admitted with first STEMI to Coronary Intensive Care Unit and who were used thrombolytic therapy was included in this retrospective study.

Cardiac autonomic function in healthy young smokers.

The present study examined the heart rate turbulence (HRT) and heart rate variability (HRV) parameters in healthy young smokers (<40 years) to assess the effects of smoking on cardiac autonomic function. The study included 75 smokers with a history of habitual smoking for at least 1 year (41 males and 34 females; mean age, 29.3 ± 7.

Glycated haemoglobin is correlated with the severity of coronary artery disease independently of traditional risk factors in young patients.

Introduction: In this study, we aimed to investigate the relationship between glycated haemoglobin (HbA1c) levels and the severity of coronary artery disease (CAD) in < 40 years old patients.

Material And Methods: The study population consisted of 211 premature coronary atherosclerotic patients (pCAP) (aged 36.4 ± 2.

A relationship between mitral valve prolapse and subtypes of supraventricular tachycardia.

Aim: The aim of this study was to investigate the frequency of mitral valve prolapse (MVP) in patients with supraventricular tachycardia (SVT) who were diagnosed by intracardiac electrophysiological study (EPS).

Method: The study was a retrospective cohort of 378 adult patients (128 males and 250 females, 17 to 63 years) admitted with EPS. We included 267 SVT patients (58.
