Little is known about the distribution and clinical course of patients with inherited arrhythmia syndrome (IAS) concomitant atrial arrhythmias (AAs).
Sodium voltage-gated channel α subunit 5 (SCN5A)-mutations may cause an array of arrhythmogenic syndromes most frequently as autosomal dominant trait, with incomplete penetrance, variable expressivity and male predominance. In the present study, we retrospectively describe a group Mexican patients SCN5A-disease causing variants in whom onset symptoms occurred pediatric age range. The study included 17 clinical diagnosis primary electrical disease, at least one SCN5A pathogenic or likely...
Background: Andersen-Tawil syndrome (ATS) is a cardiac channelopathy that inherited in an autosomal dominant way, and it characterized by triad of periodic paralysis, ventricular arrhythmias, includes some dysmorphic features with incomplete penetrance variable expression result challenging diagnosis.Objective: The objective the study was to describe extra-cardiac phenotype cohort patients ATS at risk sudden death (SCD) improve its early clinical identification.Methods: In observational,...
Abstract Short QT Syndrome (SQTS) is a highly malignant inherited primary electrical disease that associated with ventricular arrhythmias and sudden cardiac death (SCD); despite this, some patients may present different arrhythmic phenotype supraventricular affection. One particular presentation can be notably separated from others. The V141M variant the KCNQ1 gene frequently presents fetal bradycardia, atrial fibrillation, sinus, AV node dysfunction, but without single reported event of...
La terapia de resincronización cardiaca mediante estimulación hisiana ha demostrado ser efectiva en pacientes con bloqueo rama izquierda del haz His e insuficiencia cardiaca. Paciente masculino, 47 años edad, cardiaca, fracción expulsión 17% y miocardio dilatada idiopática, electrocardiograma ritmo sinusal, auriculoventricular 1.er grado, intervalo PR 400 ms, completo derecha His, fascículo anterior la duración QRS 200 ms. Se decidió realizar selectiva His. biventricular convencional...
Cardiac resynchronization therapy has proven to be an effective in patients with left bundle branch block and heart failure.Male, 47 years old, failure a ventricle ejection fraction of 17%, idiopathic failure.ECG sinus rhythm, 1 st degree AV block, PR 400 ms, complete right anterior hemi-fascicle the His, QRS duration 200 ms.We decided perform selective His pacing.In biventricular cardiac is not indicated due low treatment response.His pacing allows recruiting blocked restoring conduction...
