Right bundle branch blockVectorcardiographyArtificial cardiac pacemakerAutomated ECG interpretation: Automated ECG interpretation is the use of artificial intelligence and pattern recognition software and knowledge bases to carry out automatically the interpretation, test reporting, and computer-aided diagnosis of electrocardiogram tracings obtained usually from a patient.Third-degree atrioventricular blockParoxysmal tachycardiaPacemaker syndrome: Pacemaker syndrome is a disease that represents the clinical consequences of suboptimal atrioventricular (AV) synchrony or AV dyssynchrony, regardless of the pacing mode, after pacemaker implantation.LorcainideCystic tumour of the atrioventricular nodal region: Cystic tumour of the atrioventricular nodal region is a very rare tumour of the heart in the region of the atrioventricular node. It is also known as mesothelioma of the atrioventricular node.Ventricular dyssynchrony: In cardiology, Ventricular dyssynchrony is a difference in the timing, or lack of synchrony, of contractions in different ventricles in the heart. Large differences in timing of contractions can reduce cardiac efficiency and is correlated with heart failure.Septal myectomy: Septal myectomy is a cardiac surgery treatment for hypertrophic cardiomyopathy (HCM). The surgery entails removing a portion of the septum that is obstructing the flow of blood from the left ventricle to the aorta.Electrocardiography in myocardial infarctionTachycardiaManagement of heart failure: Management of heart failure requires a multimodal approach. It involves a combination of lifestyle modifications, medications, and possibly the use of devices or surgery.Malformative syndrome: A malformative syndrome (or malformation syndrome) is a recognizable pattern of congenital anomalies that are known or thought to be causally related (VIIth International Congress on Human Genetics).John HolterNerve block
