Cardiovascular imaging has radically changed the management of patients with arrhythmogenic cardiomyopathies. This article focuses on the role of echocardiography and MRI in the diagnosis of these structural diseases. Cardiomyopathies with hypertrophic pattern (hypertrophic cardiomyopathy, restrictive cardiomyopathies, amyloidosis, Anderson-Fabry disease, and sarcoidosis), cardiomyopathies with dilated pattern, inflammatory cardiac diseases, and right ventricular arrhythmogenic cardiomyopathy are analyzed. Finally, anatomic predictors of arrhythmias and sudden cardiac death are discussed...

Arrhythmias have acquired a specific identity in pediatric cardiology, but for pediatric cardiologists it has always been difficult to recognize and treat them. Changes in anatomy and physiology result in electrocardiogram features that differ from the normal adult pattern and vary according to the age of the child. Sinus arrhythmia, ectopic atrial rhythm, "wandering pacemaker," and junctional rhythm can be normal characteristics in children (15%-25% of healthy children can have these rhythms on the electrocardiogram)...

REVIEW
Franco Giada, Antonio Raviele
Palpitations are among the most common symptoms that prompt patients to consult a physician. In the diagnostic workup of patients with palpitations, the initial evaluation involves history, physical examination, and 12-lead electrocardiogram. These investigations yield a prognostic stratification of the patients, and a definitive suspected diagnosis of the cause of symptoms in a good proportion of cases. When the initial evaluation results are negative and the patient is suffering from heart disease, or if the palpitations are frequent or poorly tolerated and with a high probability of an arrhythmic origin, ambulatory electrocardiogram monitoring and/or electrophysiological study should be undertaken...

REVIEW
Andrea Ungar, Martina Rafanelli
Syncope is a frequent condition, owing to a transient global cerebral hypoperfusion, that may depend on a reduction of vascular total peripheral resistance and/or cardiac output. Cardiac syncope doubled the risk of death from any cause and increased the risk of nonfatal and fatal cardiovascular events. Arrhythmias are the most common cardiac causes of syncope. Both bradyarrhythmias and tachyarrhythmias may predispose to syncope. The first line evaluation relies on clinical history, physical examination, active standing test, 12-lead echocardiogram...

REVIEW

Early repolarization, Brugada syndrome, and pathologic J waves have been described for decades, but only recently experimental and clinical data have allowed reconciliation of Brugada and Early Repolarization under the common definition of J-wave syndromes. The concept was derived from studies showing, in both conditions, the presence of transmural dispersion of repolarization, localized conduction abnormalities, and abnormal transition between QRS and ST segment on electrocardiogram. Although several clinical studies have addressed the clinical presentation and epidemiology of J-wave syndromes, relevant knowledge gaps exist...

The surface ECG is a valuable mapping tool in patients with idiopathic and scar-related ventricular arrhythmias (VAs). A detailed analysis of 12-lead ECG can provide useful information in localizing the VA site of origin. This might help tailoring the ablation strategy to optimize procedural duration, increase the probability of success, and prevent complications. The aim of this article is to review the ECG features of both idiopathic and scar-related VAs and discuss their potential implications for optimizing the ablation strategy...

Wide complex tachycardia may represent a challenge for correct interpretation of standard electrocardiogram, which is crucial for proper patient management. For this reason, algorithms based on electrocardiographic criteria have been developed to guide interpretation in a step-by-step approach. Despite their greater accuracy, some cases of wide QRS complex tachycardia are a challenge. Some peculiar forms of ventricular tachycardia, and complex supraventricular substrate or particular clinical condition, may originate a challenging electrocardiographic pattern...

The common arrhythmia atrial fibrillation (AF) is incompletely understood. The mechanism of initiation and the perpetuation of AF remain speculative. This article summarizes current knowledge of the complex relationship between arrhythmias triggering AF and their long-term effects on atrial tissue, leading to perpetuation of tachycardia. It focuses on the role of the electrocardiogram (ECG) from AF diagnosis to identification of sinus P wave abnormalities predicting future occurrences. The role of ambulatory ECG recordings in managing AF and the use of frequency analysis determining degree of organization and identification of AF triggers are discussed...

Atrioventricular node reentrant tachycardia (AVNRT) is a supraventricular arrhythmia easily diagnosed by 12-lead electrocardiogram. What is far more challenging, is the understanding of the reentrant circuit in its typical and atypical presentations. The function of the atrioventricular node is still incomplete and this knowledge gap is reflected in the reconstruction of the pathways used by AVNRT in its multiform presentations. This article illustrates the heterogeneous electrocardiographic manifestations of AVNRT...

Premature complexes are electrical impulses arising from atrial, junctional, or ventricular tissue, leading to premature heart beats. Premature atrial beats are much more frequent than those arising in the atrioventricular junction but less frequent than premature beats from the ventricles. Although they are usually benign and highly prevalent in the general population, they could trigger sustained supraventricular and ventricular arrhythmias, and cause cardiomyopathies. The aim of this article was to review the main electrocardiology features of premature complexes and discuss their implications in clinical practice...

Surface electrocardiograms, both resting 12-lead electrocardiographs and ambulatory electrocardiograph monitoring, play an essential role in establishing indications for cardiac implantable electronic devices (pacemakers, cardiac implantable defibrillators, and cardiac resynchronization therapies), and in the evaluation of patients already implanted. Current devices have prolonged memory capabilities (defined as Holter functions) and remote monitoring functions, to evaluate the electrical properties and the automatic detection of arrhythmias...

REVIEW
Fabio M Leonelli, Giuseppe Bagliani, Roberto De Ponti, Luigi Padeletti
From the atrioventricular node, electrical activation is propagated to both ventricles by a system of specialized conducting fibers, His Purkinje System (HPS), guaranteeing a fast, synchronous depolarization of both ventricles. From the predivisional common stem, a right and left branch separate, subdividing further in a fairly predictable fashion. Synchronous ventricular activation results in a QRS with specific characteristics and duration of less than 110 milliseconds. Block or delay in any part of the HPS changes the electrocardiographic (ECG) morphology...

This article describes the different anatomic structures involved in normal atrioventricular conduction and their pathologic states. It defines their effects on the electrocardiogram, and describes how to localize the level and evaluate the severity of conduction disease by electrocardiographic analysis. It illustrates the relevance of intracavitary recordings in the diagnosis of level of block.

REVIEW

The sick sinus syndrome includes symptoms and signs related to sinus node dysfunction. This can be caused by intrinsic abnormal impulse formation and/or propagation from the sinus node or, in some cases, by extrinsic reversible causes. Careful evaluation of symptoms and of the electrocardiogram is of crucial importance, because diagnosis is mainly based on these 2 elements. In some cases, the pathophysiologic mechanism that induces sinus node dysfunction also favors the onset of atrial arrhythmias, which results in a more complex clinical condition, known as "bradycardia-tachycardia syndrome...

This article reconstructs the steps leading to the identification of the atrioventricular block, from its first descriptions to current studies, highlighting the roles of Arthur Keith (1866-1955) and Martin Flack (1882-1931), who contributed to establish the theoretic basis for electrocardiography.
