Short-QT syndrome (SQTS) is a recently recognized disorder associated with atrial fibrillation (AF) and sudden death due to ventricular arrhythmias. Mutations in several ion channel genes have been linked to SQTS; however, the mechanism remains unclear. This study describes a novel heterozygous gain-of-function mutation in the inward rectifier potassium channel gene, KCNJ2, identified in SQTS.

Ablation of supraventricular tachycardia in elderly persons presents a challenging problem to electrophysiologists. Friable cardiac structures, prone to catheter perforation, comorbid cardiovascular disease, and the propensity to develop atrial fibrillation and thromboembolic complications, place these patients at high risk. Newer techniques for cardiac mapping and ablation, the establishment of precise ablation lines, and safer approaches to the ablation mechanism (particularly for atrial fibrillation) are presented in this review.

The authors review the state-of-the-art on ventricular pre-excitation in medical and arrhythmological literature in order to facilitate the recognition of the various clinical forms, like classic and occult Wolff Parkinson withe syndrome and Lown Ganong Levine syndrome. A historical introduction reviews our electrophysiopathological knowledge of the electrical activation and conduction of ventricular pre-excitation compared to normal, starting from the anatomic discovery of conduction pathways to the possible use of transesophageal electrostimulation and endocavity mapping to study electric potentials. Avantgarde technologies have also been developed to eliminate anomalous pathways firstly by using a direct current dirscharge and secondly radiofrequency.

Sudden death (SD) in ventricular preexcitation (VP) syndrome is believed to be the result of atrial fibrillation with rapid ventricular response over the accessory pathway. Previous reports are anecdotal and often lack autopsy validation.
Prevalence and clinicopathological features of VP were investigated in a series of 273 SDs in children and young adults (aged

Cardiac conduction abnormalities have been reported in families with Leber's hereditary optic neuropathy (LHON). The pre-excitation syndrome Wolff-Parkinson-White syndrome or Lown-Ganong-Levine syndrome, is reportedly common in Finns with LHON, being seen in 14 (9%) of the 163 individuals with mitochondrial DNA (mtDNA) mutations. While this syndrome is thought to be rare in other ethnic groups with LHON, the present study of 35 Japanese LHON families confirmed that it is also relatively common among Japanese families, being seen in 5 (8%) of the 63 individuals with mtDNA mutations.

Ventricular preexcitation syndromes (VPS) are very important between cardiac rhythm disturbances in childhood, because their presence can change the clinical and ECG picture and thus the treatment can be very difficult. The authors studied 58 cases of VPS in children (2 weeks-15 years old) admitted in a period of 3 years. The surface ECG showed VPS aspects: in 30% of cases we noticed WPW syndrome type B and the rest presented VPS with Mahaim pathways and Lown-Ganong-Levine syndrome.

The aim of this study was to assess use-dependence in patients with ventricular premature contractions (VPC's) treated with propafenone, by means of the increase in heart rate using transesophageal atrial pacing. It was also analyzed whether this phenomenon was related to the antiarrhythmic effect. Fifteen patients with more than 30 symptomatic VPC's/sour were evaluated.

The basic anatomical substrate of enhanced A-V nodal conduction, manifesting or not as Lown-Ganong-Levine syndrome, is still a controversial issue. We describe the case of a 34-year-old man who presented episodes of ventricular fibrillation. Electrophysiological studies showed that the AH interval was 55 ms, and increased by only 20 ms at paced cycle lengths of 300 ms; atrial pacing induced atrial fibrillation, with a shortest RR interval of 240 ms.

Primary prolapse of the mitral valve was diagnosed in 27 (11.7%) out of 230 patients with preexcitation syndrome: 10 of them presented with Wolff-Parkinson-White syndrome, 15 with Clerc-Lévy-Critesco syndrome, and two patients with combination of both syndromes. Preexcitation syndrome combined with mitral valve prolapse manifested itself by different disorders of the cardiac rhythm, mainly by the supraventricular forms: by PST in 17, nonparoxysmal tachycardia in 1, atrial fibrillation paroxysms in 7, sinus tachycardia in 2, supraventricular extrasystole in 3, pacemaker migration in the atria in 1 patient.

Medico-genetic studies including preparation of the family pedigree, interviews, examinations, electro- and echocardiography were carried out in the families of 75 patients with pre-excitation syndrome (PES). Of these, 35 patients presented with Wolff-Parkinson-White (WPW) syndrome and 40 with Clerc-Lévy-Cristesco (CLC) syndrome. The studies made in possible to define the autosomal-dominant type of the syndrome or PES inheritance and to diagnose for the first time WPW syndrome in 3, PES in 1, CLC syndrome in 32 and CLC phenomenon in 89 persons out of 233 relatives of the first and second degree kinship.

Three cases of the LGL syndrome are reported. In the first case the syndrome was associated with hyperthyroidism, in the second case ECG abnormalities suggested focal myocardial ischaemia, in the third case pre-excitation coexisted with combined valvular heart disease. Attention is called to frequent occurrence of the pre-exitation syndrome with certain disease entities.

The term "enhanced atrioventricular nodal conduction" (EAVN) is used to indicate an electrophysiologic condition characterized by subnormal conduction delay with reduced decremental properties in the AV node, which can be responsible for rapid ventricular rates in the event of fast atrial rhythms. Although identification of such an entity usually requires definition of the AV conduction intervals, some authors have suggested that EAVN can be diagnosed, by means of atrial pacing only, when 1:1 conduction with narrow QRS complexes occurs during atrial pacing at rate higher than 200 bpm. The use of incremental transesophageal atrial pacing (TAP) as a noninvasive tool for identification of EAVN was investigated in 19 patients.

The efficacy and side-effects of adenosine for treatment of supraventricular arrhythmias were compared to verapamil therapy in patients presenting to the emergency room. Clinical variables and the time interval from the initiation of treatment to the termination of the supraventricular tachycardia, as well as the time from the initial effective dose of medication to the termination of supraventricular tachycardia were compared for adenosine and verapamil. Adenosine was given to a total of 44 patients, 16 patients in the electrophysiology laboratory, and 28 patients in the emergency room for evaluation and termination of their tachycardia.

To study the characteristics of the ventriculoatrial conduction system in patients capable of rapid antegrade atrioventricular conduction, electrophysiologic studies were performed in 23 subjects capable of 1:1 atrioventricular conduction at atrial cycle lengths less than or equal to 300 ms (Group I), and in 23 subjects with normal 1:1 atrioventricular conduction (Group II). During ventricular pacing, ventriculoatrial block at all cycle lengths was seen in 5/23 (22%) in Group I and in 7/23 (30%) in Group II patients (p = NS). In the remainder, the minimum ventricular pacing cycle length maintaining 1:1 ventriculoatrial conduction was 359 +/- 85 ms in Group I, compared to 444 +/- 118 ms in Group II (p less than .

An electrophysiological exploration was carried out in 48 patients presenting a syndrome short PR-small QRS (group I), compared to a reference group of 537 patients who did not present this abnormality and had no previous history of Bouveret's tachycardia (group II). The most remarkable abnormality in group I is an acceleration of the anterograde nodal conduction with a Wenckebach point beyond 200/min, significantly more frequent than in group II. The retrograde conduction is also excellent in group I, but without significant difference in comparison to patients from group II who have an accelerated anterograde conduction.

21 patients with Wolff-Parkinson-White (WPW) syndrome were investigated through radionuclide imaging and body surface mapping. Ventricular preexcitation was localized by display of identical phase ventricular regions (phase display). In 79% of the cases radioisotope and body surface mapping methods have identical results for the site of preexcitation.

A new syndrome of ventricular pre-excitation syndrome is differentiated--of additional obscure retrograde conducting ventricular-atrial connection, different from the so far known syndrome of Wolff-Parkinson-White, Lown-Ganong-Levine and syndrome of Mahaim. That is determined by the anatomically confirmed additional connection, conducting only retrogradely from ventricles to auricle. Diagnostic criteria have been developed from the most significant clinical symptoms and electrocardiographic constellations.

Preexcitation syndromes are rare disturbances of the atrioventricular excitation transmission in direct fetal electrocardiograms. As example we report on a fetal Lown-Ganong-Levine (LGL)-syndrome. This is to differentiate from the Wolff-Parkinson-White (WPW)-syndrome, which is possible by typical changes in the QRS-complex.
