135 Possible Causes for 1 atrioventricular block, Exertional Syncope

  • Orthostatic Hypotension

    Childhood: Children with DBH deficiency have markedly reduced exercise capacity, perhaps because of hypotension engendered by physical exertion.[ncbi.nlm.nih.gov] We describe the case of an 81-year-old male patient with long PR interval and episodes of 2:1 atrioventricular block, in whom the implantation of a dual chamber pacemaker[ncbi.nlm.nih.gov] The syncope associated with postural hypotension often suggests seizures and prompts trials of anticonvulsive medication despite lack of abnormalities on the electroencephalogram[ncbi.nlm.nih.gov]

  • Third Degree Atrioventricular Block

    Before we return to the case study, we will cover the rules for differentiation of atrioventricular blocks on the ECG: A 1 Atrioventricular Block is not a block, per se, but[ems12lead.com] ECG Examples: Third-Degree Atrioventricular (AV) Block ECG (Example 1) Third-Degree Atrioventricular (AV) Block ECG (Example 2) Third-Degree Atrioventricular (AV) Block ECG[healio.com] Previous article Next article CASE REPORT Year : 2012 Volume : 6 Issue : 1 Page : 61-64 Unusual diagnosis of a persistent third-degree atrioventricular block during anesthesia[saudija.org]

  • Hypertrophic Cardiomyopathy

It occurs more commonly in children and young adults.[symptoma.com]

  • Recurrent Pulmonary Embolism

    The electrocardiogram on admission showed a regular sinus rhythm with a ventricular rate of 90 beats per minute, a QRS axis at 70o, a 1 st degree atrioventricular block (PR[tmj.ro] […] interval 0.24 sec), an incomplete right bundle branch block and non-specific ST-segment abnormalities: 1 mm ST elevations in DI, DII and aVL. ( Fig. 1 ) The chest radiography[tmj.ro]

  • Restrictive Cardiomyopathy

    Is there a personal history of unexplained syncope or near syncope? Is there a personal history of dyspnea or fatigue with exercise?[aafp.org] I44.0 Atrioventricular block, first degree I44.1 Atrioventricular block, second degree I44.2 Atrioventricular block, complete I44.3 Other and unspecified atrioventricular[icd10data.com] He denied other associated diseases, except for syncope with permanent pacemaker implantation one year before the onset of symptoms of heart failure.[scielo.br]

  • 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] 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] 1.[synonym.com]

  • Ayerza Syndrome

    Complete atrioventricular block complicating acute myo- cardial infarction in the thrombolytic era. J Am Coll Cardiol 1999;34:1721–1728. 116.[cardiologieladomiciliu.ro] Incidence, predictors, and outcomes of high-degree atrioventricular block complication acute myocardial infarction treated with thrombolytic therapy.[cardiologieladomiciliu.ro] J Cardiovasc Electrophysiol 2006;17:1–5. 115. Harpaz D, Behar S, Gottlieb S et al., SPRINT Study Group, the Israeli Thrombolytic Survey Group.[cardiologieladomiciliu.ro]

  • Congenital Heart Block

    Exertional atrioventricular block presenting with recurrent syncope: successful treatment by coronary angioplasty. Heart 1996;75:640–641.[link.springer.com] INTRODUCTION Congenital complete atrioventricular block (CAVB) occurs rarely, occurring in approximately 1 of every 20 000 newborns.[revespcardiol.org] Symptoms Symptoms associated with SND vary from no symptoms to fatigue, bradycardia (slow heart rate), syncope (fainting), shortness of breath at rest or with exertion, and[pediatricepsociety.org]

  • Second Degree Atrioventricular Block

    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] "Low-risk" features, which suggest EV-AVB, are the absence of heart disease, a long-standing history of recurrent syncope, the occurrence of syncope after exertion or after[ncbi.nlm.nih.gov]

  • Syncope

    , especially exertional syncope, can be caused by left ventricular outflow tract obstruction.[resus.me] Diagnosis of Paroxysmal Atrioventricular Block According to Type of Conduction Disturbance.[revespcardiol.org] Post-exertional syncope as a neurally mediated reflex normally occurs after exercise , whereas syncope from outflow tract obstruction occurs during exercise .[geekymedics.com]
