57 Possible Causes for 1 atrioventricular block, Exertional Syncope, Wide QRS Complex

  • 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 features of 3rd degree AV block On the ECG P-waves have no relation to the QRS complexes. The QRS complexes may be normal or wide.[ecgwaves.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]

    The block is at the level of atrioventricular (AV) node. 2:1 AV block is generally accepted as a variant of the Wenkebach phenomenon. ECG 1.[metealpaslan.com] As a result, the QRS complex may be narrow (if located in the bundle of His) or wide (if located in the bundle branches).[aibolita.com] Many times patients are asymptomatic at rest, but have significant symptoms with exertion.
