A comprehensive meta-analysis on relationship between CYP11B2 rs1799998 polymorphism and atrial fibrillation
The correlation between CYP11B2 rs1799998 polymorphism and atrial fibrillation (AF) was analyzed by several studies, but the results of these studies were inconsistent. Thus, we performed this study to obtain a more conclusive result on relationship between CYP11B2 rs1799998 polymorphism and AF. (Source: Journal of Electrocardiology)

Shift in the retrograde atrial activation sequence after radiofrequency catheter ablation in left variant atypical atrioventricular nodal reentrant tachycardia
We describe an unusual case of “left-variant” atypical AVNRT, where change in the retrograde earliest atrial activation site (REAAS) at the coronary sinus (CS) following radiofrequency catheter ablation (RFCA) was observed. Our observation suggests that the REAAS, that is, the left AVN connections, could participate in the formation of the reentrant circuit of “left-variant” atypical AVNRT.

The role of heart rate variability, heart rate turbulence, and deceleration capacity in predicting cause-specific mortality in chronic heart failure
The volume of regional denervated myocardium (D-M) on positron emission tomography has been recently suggested as a strong independent predictor of cause-specific mortality from sudden cardiac arrest (SCA) in chronic heart failure. We sought to evaluate whether ECG indices of global autonomic function predict risk of SCA to a similar degree as regional D-M. (Source: Journal of Electrocardiology)

Unexpected reappearance of ST elevation in the anterior precordial leads shortly after an acute anterior myocardial infarction
Brugada syndrome (BrS) is an inherited congenital electrical abnormality characterized by right precordial ST-segment elevation that predisposes patients with apparent structurally normal hearts to malignant ventricular arrhythmias and sudden cardiac death. The diagnosis of BrS is based on typical ECG characteristics along with symptoms and familial history. Brugada phenocopy (BrP) encompasses a number of clinical entities characterized by ECG patterns that, while identical to true BrS, are elicited by various clinical conditions (i.e., metabolic conditions, mechanical compression, myocardial ischemia, myocardial/pericardi...

Continuous heart rate monitoring for automatic detection of atrial fibrillation with novel bio-sensing technology
Asymptomatic atrial fibrillation [AF] is an important cause of fatal or disabling stroke. A continuous heart-rate monitoring device, comfortable enough to be worn continuously and reliable enough to detect AF, would allow for prompt initiation of anticoagulation therapy to prevent stroke.

Case report: Apical variant hypertrophic cardiomyopathy simulating an acute inferior myocardial infarction
We present a female patient who arrived to the emergency department with chest pain without known medical history at the time of consultation. Considering her risk factors and electrocardiographic findings, it was decided to perform a coronary catheterization under the suspicion of acute myocardial infarction. The catheterization and another studies was negative for coronary artery disease. Additional studies were conclusive for apical variant hypertrophic cardiomyopathy or Yamaguchi syndrome.

Electrocardiographic changes after implantation of a left ventricular assist device – Potential implications for subcutaneous defibrillator therapy
Implantation of a left ventricular assist device (LVAD) leads to a diverse spectrum of changes on the twelve-lead surface electrocardiogram (ECG). We aimed to elucidate the changes of the surface ECG in patients after LVAD implantation potentially impacting ECG based screening tests of subcutaneous implantable cardioverter-defibrillators (S-ICD).

Long –term prognostic significance of terminal QRS distortion on patients with stemi and its correlation with the GRACE scoring system
The standard 12-lead electrocardiogram (ECG) continues to serve as the most widely used tool in the diagnosis and risk stratification of patients with acute ST-segment elevation myocardial infarction (STEMI) and several new ECG parameters have been shown to be useful in determining patients at higher risk [1 –3].

Automatic atrial fibrillation and flutter detection by a handheld ECG recorder, and utility of sequential finger and precordial recordings
Handheld ECG recorders may have algorithms which automatically inform the user of presence of arrhythmia. The main objectives of this study were to evaluate the accuracy of the arrhythmia diagnosis algorithm of Beurer ME90 recorder to diagnose atrial fibrillation (AF)/flutter, and to evaluate whether recording technique (finger versus precordial) affects diagnostic performance.
