Neonatal arrhythmias: diagnosis, treatment, and clinical outcome
Arrhythmias in the neonatal period are not uncommon, and may occur in neonates with a normal heart or in those with structural heart disease. Neonatal arrhythmias are classified as either benign or nonbenign. Benign arrhythmias include sinus arrhythmia, premature atrial contraction, premature ventricular contraction, and junctional rhythm; these arrhythmias have no clinical significance and do ...
متن کاملCorrelative electrophysiological and anatomical studies concerning the site of origin of escape rhythm during complete atrioventricular block in the dog.
Complete heart block was produced in eight dogs by the selective perfusion of physostigmine or neostigm into the atrioventricular (AV) node artery. A characteristic escape AV junctional rhythm emerged in each dog. After reversal of the cholinesterase paralysis with atropine, in each dog partial heart block was produced by an incision into the AV nodal region. In three of these eight dogs, a sec...
متن کاملSpontaneous Resolution of Junctional Rhythm in a Child with Dengue Fever
Atypical manifestations of dengue fever are rising but they may be under reported. In dengue hemorrhagic fever (DHF), cardiac rhythm abnormalities observed were ventricular arrhythmia, atrial fibrillation and atrioventricular block. Here we report an 11 year old boy who presented with dengue fever and developed bradycardia and hypotension. His electrocardiogram (ECG), during the bradycardia, sh...
متن کاملReversible cardiogenic shock caused by atrioventricular junctional rhythm after percutaneous coronary intervention
An 82-year-old female patient undergoing cardiogenic shock caused by atrioventricular junctional rhythm immediately after percutaneous coronary intervention (PCI) is described. Pharmacotherapy was invalid, and subsequent application of atrial pacing reversed the cardiogenic shock. PCI-related injury of sinuatrial nodal artery leading to acute atrial contractility loss, accompanied by atrioventr...
متن کاملSite of origin and molecular substrate of atrioventricular junctional rhythm in the rabbit heart.
During failure of the sinoatrial node, the heart can be driven by an atrioventricular (AV) junctional pacemaker. The position of the leading pacemaker site during AV junctional rhythm is debated. In this study, we present evidence from high-resolution fluorescent imaging of electrical activity in rabbit isolated atrioventricular node (AVN) preparations that, in the majority of cases (11 out of ...
