Pre-excitation induced ventricular dysfunction and successful berlin heart explantation after accessory pathway ablation
A 13 kg, 20 month-old, Caucasian girl, presented with cardiomyopathy, biventricular dysfunction and pre-excitation on electrocardiogram. She had normal intracardiac anatomy with severely dilated left ventricle and severely diminished biventricular function (Fig. 1). She was treated with milrinone an d epinephrine infusions, mechanical ventilation and listed for heart transplant. She underwent Berlin Heart EXCOR biventricular assist device (BiVAD) placement (30 ml LVAD and 25 ml RVAD pumps). No supraventricular tachycardia (SVT) was inducible or noted during her hospitalization. (Source: Journal of Electrocardiology)

Prognosis and first diagnostic ECG in STEMI patients referred to the emergency medical system for primary PCI
When assessing time to reperfusion in ST-segment elevation myocardial infarction (STEMI) patients, we refer to time points which may be objectively obtained, such as the Emergency Medical System (EMS) call, the time of the first qualifying electrocardiogram (ECG), the door time or the time of cardiac catheterization laboratory (cath-lab) in which recanalization of the culprit coronary is attained. These time points are currently used to measure the system delay in delivering primary percutaneous coronary intervention (PCI) [1]. (Source: Journal of Electrocardiology)

Prognostic value of electrocardiographic time intervals and QT rate dependence in hypertrophic cardiomyopathy
Preventing sudden cardiac death (SCD) is one of the main goals in hypertrophic cardiomyopathy (HCM). Many variables have been proposed, however the European and American guidelines do not incorporate any ECG or Holter monitoring derived variables other than the presence of ventricular arrhythmia in their risk stratification models. In the present study we evaluated electrocardiographic parameters in risk stratification of HCM. (Source: Journal of Electrocardiology)

Atypical advanced interatrial blocks: Definition and electrocardiographic recognition
The diagnosis of advanced interatrial block (A-IAB) is done by surface ECG analysis when the P-wave ≥120 ms with biphasic (±) morphology in leads II, III and aVF. In this brief communication, we advance a new concept involving atypical patterns of A-IAB due to changes about the morphology or duration of the P-wave. It remains to be determined its real prevalence in different clinical scenario s, and whether these atypical ECG patterns should be considered as predictors of atrial fibrillation/stroke.

An algorithm for the differentiation of the infarct territory in difficult to discern electrocardiograms
In this study, we sought ECG clues which may facilitate discriminating (1) MI location and then (2) culprit artery in patients with difficult-to-discern ECGs. (Source: Journal of Electrocardiology)

More on the pacemaker ECG in severe hyperkalemia
We thank Tomcs ányi and Bózsik [1] for their interest in our work [2] and allowing us to further elaborate on electrocardiographic (ECG) signs of severe hyperkalemia. We agree that in patients with pacemakers, conventional ECG markers of hyperkalemia are frequently lacking and therefore, any sign that can lead t o this important clinical diagnosis is welcome. As Tomcsányi and Bózsik have pointed out, well established manifestations include marked widening of the paced QRS complexes [3] as well as any type of failure of pacemaker sensing and capture [4].

ECGI in atrial fibrillation: A clinician's wish list
Have we a challenge of credibility in the invasive treatment of atrial fibrillation (AFIB)? The incidence of AFIB in the European Union (EU) is about 600,000 cases per year, while only 100,000 get an invasive treatment with a failure rate of close to 40%. Those that remain in AFIB need two times more hospitalizations and three times more re-hospitalizations. AFIB accounts for over 1% of the EU health care costs. Too many patients are not referred and the indication rates of cardiac ablation are inexplicably variable throughout the EU. (Source: Journal of Electrocardiology)

The role of mexiletine in the management of long QT syndrome
Congenital long QT syndrome (LQTS) is a hereditary cardiac disorder characterized by QT-interval prolongation and T-wave abnormalities on electrocardiogram (ECG), and is associated with an increased risk of torsade de pointes and sudden cardiac death. Beta-blocker medication is effective in most patients except those with a very slow heart rate. Increased late sodium currents (INa-L) can result in bradycardia-dependent QT prolongation. Mexiletine, an inhibitor of INa-L, is not only effective in treating type-3 LQTS, but also shows the promise in managing LQTS patients of other genotypes with markedly prolonged QT interval ...

Persistent but reversible advanced atrio-ventricular block in a heart transplant man induced by dobutamine stress echocardiography
We report a heart transplant patient with high cardiovascular risk who developed symptomatic advanced AV block during DSE which persisted after termination of dobutamine administration, necessitating pacemaker implantation. To our knowledge, this is the first published case of persistent high grade AV block in a heart transplant patient induced by DSE. (Source: Journal of Electrocardiology)

What is ventricular fibrillation undersensing?
Ventricular fibrillation (VF), uninterrupted, is fatal within minutes. Implantable cardioverter defibrillators (ICDs) sense ventricular electrograms (EGMs) during VF and detect the VF rhythm (a sequence of VF sensed events) to deliver a shock to terminate VF and save lives. VF sensing and detection in Medtronic ICDs has been reported to be highly sensitive. However, Castellano et al. reported that Medtronic ICDs have the potential for high levels of undersensing in VF, sufficient to underdetect VF and withhold life-saving therapy.

Wavelet leader multifractal analysis of heart rate variability in atrial fibrillation
Accurate and timely detection of atrial fibrillation (AF) episodes is important in primarily and secondary prevention of ischemic stroke and heart-related problems. In this work, heart rate regularity of ECG inter-beat intervals was investigated in episodes of AF and other rhythms using a wavelet leader based multifractal analysis. Our aim was to improve the detectability of AF episodes. (Source: Journal of Electrocardiology)
