AIMS: 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. METHODS AND RESULTS: We studied an 8-year-old girl with a markedly short-QT interval (QT = 172 ms, QTc = 194 ms) who suffered from paroxysmal AF...

This report describes a 3-month-old boy with isolated left ventricular noncompaction admitted to a medical facility due to heart failure and dysrhythmia. His electrocardiogram showed a short PR interval and a normal QRS complex after abortion of supraventricular tachycardia in favor of Lown-Ganong-Levine syndrome or enhanced atrioventricular nodal conduction.

The aim of the study was to evaluate the prevalence of electrocardiography (ECG) abnormalities in subjects with spontaneous pneumothorax. Forty consecutive patients (mean age 43.7 +/-19.1 years) with spontaneous pneumothorax participated in the study. There were 22 cases of left-sided and 18 cases of right-sided pneumothorax. The mean relative volume of pneumothorax was 51.4 +/-24.7% according to the Light's index and 53.5 +/-22.9% according to the Rhea method. Heart rate was significantly higher in patients with pneumothorax than after lung re-expansion (91 +/-20 bpm vs...

Leonard S Dreifus, Scott J Pollak
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...

A patient with Lown-Ganong-Levine syndrome, in whom electrophysiologic evaluation revealed nodoventricular accessory connections, is described. The resting electrocardiographic pattern, which is unusual in patients with Mahaim type of preexcitation, was due to relatively short A-H and H-V intervals. Electrophysiologic study is indispensable for exact diagnosis in patients with preexcitation syndromes.

BACKGROUND: Lown-Ganong-Levine syndrome is characterized by paroxysmal supraventricular tachycardia, a short PR interval, and normal QRS. CASE: A gravida 3, para 2 was diagnosed with Lown-Ganong-Levine syndrome at 16 weeks' gestation after an episode of chest pain and shortness of breath. She was hospitalized and treated with digoxin, and her symptoms subsided. The remainder of her pregnancy was uneventful. CONCLUSION: Lown-Ganong-Levine Syndrome is a rare complication most commonly seen in young to middle-aged women...

A 40-year-old man with Fabry disease, confirmed by decreased leukocyte alpha-galactosidase A activity in 2001, complained of sudden bilateral deafness, as evidenced by clinical history and audiometry. Magnetic resonance of the brain revealed features typical of Fabry disease. Other clinical manifestations of the disease included: angiokeratoma, mild proteinuria with normal renal function, lymphoedema of the lower limbs, pre-excitation syndrome, myocardial hypertrophy.

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...

BACKGROUND: 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. METHODS AND RESULTS: Prevalence and clinicopathological features of VP were investigated in a series of 273 SDs in children and young adults (aged <or=35 years). Site of accessory atrioventricular (AV) connection was predicted by 12-lead ECG...

BACKGROUND: Patients with the combination of bundle-branch block and ischemic heart disease have a poor outcome. There is no established criterion for detection of transient ischemia when bundle-branch block is present. OBJECTIVE: To elucidate vectorcardiographic changes during coronary angioplasty of patients with bundle-branch block. DESIGN AND METHODS: The QRS complex and ST-segment changes of 29 patients with bundle-branch block were studied during elective coronary angioplasty using continuous vectorcardiography...

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. 4 cases were familial and 1 child a hidden WPW syndrome...

COMPARATIVE STUDY
Y Mashima, K Kigasawa, H Hasegawa, M Tani, Y Oguchi
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...
