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 ...

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.

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.

Atrioventricular block revisited
Comprehensive Therapy, 2002AV blocks, their definitions and significance, are discussed. Type II, second-degree AV block is infranodal, whereas 2/3 of Type I with BBB are infranodal, 2:1 AV block is neither Type I nor II block. Infranodal blocks require pacing regardless of symptoms.

New England Journal of Medicine, 1975
The development of His-bundle (H) electrocardiography and the concept of hemiblocks have prompted a re-examination of conventional thinking about the indications for treatment of atrioventricular (AV) block. The technic of treatment is not the issue; ventricular pacemaking is the only really effective and reliable method. The problem for this review is

British Journal of Cardiac Nursing, 2010
I wish to comment on the ECG of the month in the June 2010 issue of British Journal of Cardiac Nursing. The answer states that the ECG shows ‘Mobitz type II 2:1 AV block.’ Mobitz type II block refers to the presence of non-conducted sinus P waves without preceding lengthening of the PR interval, in contrast to Mobitz type I (Wenckebach) block, in ...

Atrioventricular Block and Atrioventricular Dissociation
2004Atrioventricular (AV) block is not only linked to some important electropathophysiologic mechanisms such as conduction slowing and escape rhythm, but also to typical ECG patterns such as Wenckebach period or Mobitz block, and to other potential precursors of complete AV block such as fascicular blocks and their combinations. All in all, AV block in its

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.
