25 Possible Causes for 1 atrioventricular block, Cardiac Electrophysiologic Study Abnormal, Exertional Syncope

  • Adams-Stokes Syndrome

    Adams and Stokes found their patients to have fatty degeneration of the cardiac muscle, and considered this to be the cause of the slow pulse and attacks of syncope.[annals.org] 1.[synonym.com] This is of a particular importance when heart rate slows abruptly because a sudden decrease in heart rate, secondary to a sudden onset of high-grade atrioventricular block[bmj.com]

  • Wolff-Parkinson-White Syndrome

    He did not give any history of palpitation, dyspnoea on exertion, syncope, dizziness or chest pain.[ncbi.nlm.nih.gov] INTRODUCTION Congenital complete atrioventricular block (CAVB) occurs rarely, occurring in approximately 1 of every 20 000 newborns.[revespcardiol.org] What is Electrophysiology Study with Ablation? An electrophysiology (EP) study is a cardiac catheterization which evaluates the electrical system of the heart.[uwhealthkids.org]

  • Left Bundle Branch Block

    Case 2: This 89 yo m presented after syncope during exertion, with no chest pain.[hqmeded-ecg.blogspot.com] The ECG revealed left bundle branch block (LBBB) and 2:1 atrioventricular block (AVB) and the patient was admitted for pacemaker implantation.[ncbi.nlm.nih.gov] Variations from a normal QRS pattern indicate heart disease. block [ blok ] 1. to obstruct. atrioventricular block 1. any interruption of the conduction of electrical impulses[medical-dictionary.thefreedictionary.com]

    Case 2 was a 31-year-old woman with first-degree AV block and complete right bundle branch block with dyspnea on exertion and occasional syncope.[ncbi.nlm.nih.gov] Atrioventricular block, incomplete, mobitz type 1 Atrioventricular block, second degree AV block, high degree AV block, Mobitz type 1 AV block, second degree Electrocardiogram[icd9data.com] Therefore, in preoperative patients with suspicious infranodal AV conduction abnormalities, like our presented case, cardiac electrophysiological studies should be conducted[jaclinicalreports.springeropen.com]

  • AV Block Mobitz I

    Many times patients are asymptomatic at rest, but have significant symptoms with exertion. The risk of syncope with trauma should be assessed.[thecardiologyadvisor.com] The block is at the level of atrioventricular (AV) node. 2:1 AV block is generally accepted as a variant of the Wenkebach phenomenon.
