Electrocardiography of Atrioventricular Block
Cardiology Clinics, 2021Delayed atrioventricular (AV) conduction most commonly occurs in the AV node, resulting from AH prolongation on an intracardiac electrocardiogram and PR prolongation on a surface electrocardiogram. AV conduction may be blocked in a 2:1 manner, with a normal PR interval and wide QRS suggesting infranodal disease, whereas a prolonged PR interval and ...

Pathology of Atrioventricular Block
Cardiology Clinics, 1984This article provides a summary of the types of congenital atrioventricular block and the various acquired diseases in which atrioventricular block may occur. Some lesions found in atrioventricular block are illustrated.

Paroxysmal atrioventricular block
Heart Rhythm, 2009Paroxysmal atrioventricular block (AVB) is a poorly defined clinical entity characterized by abrupt and unexpected change from 1:1 atrioventricular conduction to complete heart block, leading to syncope and potential sudden cardiac death. Although a dangerous condition because of unreliable escape mechanism, proper diagnosis of paroxysmal AVB is often ...

Classification of Atrioventricular Block
Postgraduate Medicine, 1973The site of atrioventricular block determines its clinical significance and, hence, the proper mode of treatment or implantation of an electronic pacemaker. For practical purposes, the site of block can be identified in most instances by the duration of the QRS complex.

AACN Advanced Critical Care, 1992
The presentation of atrioventricular block in the critical care setting and the assessment parameters that the critical care nurse may use to aid in the determination of the severity of atrioventricular block are described. The underlying pathophysiology of atrioventricular block is examined to enhance the nurse’s understanding of the rationale for ...

Atrioventricular block and problems with atrioventricular conduction
Clinics in Geriatric Medicine, 2002This chapter has summarized briefly the current state of our knowledge on the incidence, etiology, presentation, investigation, and management of patients with AV block. The scope of the material covered has been widened intentionally to include a plethora of AV-conduction abnormalities because of the increases in the understanding of their clinical ...

Therapy of Atrioventricular Block
New England Journal of Medicine, 1968First-Degree Block PROLONGATION of the PR interval beyond 0.20 second may occur in many disorders including acute myocardial infarction, aortic stenosis, severe aortic insufficiency, adrenal insufficiency, rheumatic fever and a number of systemic infectious diseases.

Intramyocardial Block in Patients with Atrioventricular Block
Journal of Investigative Medicine, 2018Atrioventricular (AV) block has been extensively studied. However, conduction inside the myocardium in patients with AV block has not been reported. In this study, we aimed to demonstrate the presence of intramyocardial block in patients with AV block.

Differentiation of atrioventricular blocks
Journal of PeriAnesthesia Nursing, 1998In closing, it has been the purpose of this article to present and elaborate on the types of AV blocks, their clinical significance and causes, nursing interventions, and treatments associated with their management. The nurse that has knowledge of these heart blocks will be well equipped and prepared to promptly treat a patient suffering from AV block.
