42 Possible Causes for Cardiac Electrophysiologic Study Abnormal

  • Cardiac Arrhythmia

    Our Heart and Vascular Institute’s Cardiac Arrhythmia Program focuses on electrophysiology or EP, which is the study and treatment of abnormal heart rhythms.[dignityhealth.org] Cath indicates catheterization; echo, echocardiography; EP, electrophysiological study; ABN, abnormality; and SVT, supraventricular tachycardia. Figure 13.[doi.org] Our EP services are part of our cardiac catheterization laboratory (Cath Lab).[dignityhealth.org]

  • Wolff-Parkinson-White Syndrome

    What is Electrophysiology Study with Ablation? An electrophysiology (EP) study is a cardiac catheterization which evaluates the electrical system of the heart.[uwhealthkids.org] On the basis of transesophageal (24 patients) or intracardiac (5 patients) electrophysiologic study, 11 patients were considered at high risk for sudden death.[ncbi.nlm.nih.gov] It can help discover the cause of palpitations (a racing heart), abnormal heart rhythms or fainting, and it may also be used evaluate patients who have WPW.[uwhealthkids.org]

  • Brugada Syndrome

    Brugada Syndrome (BrS) is an inherited channelopathy causing sodium channel dysfunction in cardiac myocyte. These patients are prone to develop Ventricular Fibrillation (VF) or polymorphic Ventricular Tachycardia (VT). Next to coronary artery disease and cardiomyopathies, BrS is an important cause of sudden[…][ncbi.nlm.nih.gov]

  • Lown-Ganong-Levine Syndrome

    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[…][ncbi.nlm.nih.gov]

  • Conduction Disorder of the Heart

    Podcast: Play in new window Download Sinoatrial node SA node, sinus node The “pacemaker” Located in the right atrium Specialized cells that generate the electrical impulse which travels through the heart causing it to beat. The normal rate at which the SA node will fire is between 60 and 100 times per minute. Normal[…][physicianassistantexamreview.com]

  • Adams-Stokes Syndrome

    Abstract Using strictly defined criteria of significant arrhythmias, long term electrocardiographic recording has been evaluated for confirmation of arrhythmias as the cause of cerebral symptoms in 81 patients with suspected Adams-Stokes syndrome. Extension of long term electrocardiographic recording for more[…][ncbi.nlm.nih.gov]

  • Left Bundle Branch Block

    The presence of a left bundle-branch block (LBBB) among firefighters raises questions about stratifying risk of subsequent cardiovascular events as this conduction disorder may mask underlying coronary artery disease. This report describes the case of a firefighter with a history LBBB with exertional dyspnoea[…][ncbi.nlm.nih.gov]

  • Right Bundle Branch Block

    Coil embolization is a safe therapy for pulmonary arterio-venous malformations (PAVMs). We report the case of a 72-year-old woman affected by hereditary hemorrhagic teleangectasia who experienced right bundle branch block and atrial fibrillation 36 hours after embolization of an extended PAVM. To our knowledge,[…][ncbi.nlm.nih.gov]

  • Left Posterior Fascicular Block

    Verapamil-sensitive, idiopathic left ventricular tachycardia (ILVT) with right bundle branch block configuration and left-axis deviation is known to be due to re-entry mechanism but the exact nature of reentrant circuit in ILVT is not fully elucidated. Radiofrequency (RF) ablation was applied during ventricular[…][ncbi.nlm.nih.gov]

  • Left Anterior Fascicular Block

    Left anterior fascicular block (LAFB) is an abnormal condition of the left ventricle of the heart, related to, but distinguished from, left bundle branch block (LBBB). It is caused by only the anterior half of the left bundle branch being defective. It is manifested on the ECG by left axis deviation. It is much more[…][en.wikipedia.org]
