Second-degree atrioventricular block.
1) While it is possible only one type of second-degree AV block exists electrophysiologically, the available data do not justify such a conclusion and it would seem more appropriate to remain a "splitter," and advocate separation and definition of multiple mechanisms, than to be a "lumper," and embrace a unitary concept. 2) The clinical classification of type I and type II AV block, based on pr...
متن کاملSurvival in second degree atrioventricular block
Sir, The important paper by Shaw et al (1985;53: 587-93) showed that elderly patients with persistent type I second degree heart block have a poor prognosis. They concluded that in the absence of special circumstances these patients should receive permanent pacemakers. Indications for pacemaker implantation have changed and we need to consider the findings of Shaw et al in the light of current ...
متن کاملSurvival in second degree atrioventricular block.
Two hundred and 14 patients with chronic second degree heart block were seen and followed up in the Devon Heart Block and Bradycardia Survey between 1968 and 1982.

In group 1 there were 77 patients with Mobitz type I block (mean age 69 years), in group 2, 86 patients with Mobitz type II block (mean age 74 years), and in...
متن کاملSecond-degree Atrioventricular (Mobitz 1) Heart Block in a 52-hour-old Newborn: A Very Rare Case Report
Background: Cardiac conduction disorders are rare syndromes in neonates and children. According to the literature atrial septal defect, especially ostium secundum type, is associated with atrioventricular (AV) block. Wenckebach conduction heart block is very rare in a neonate; however, there is a dearth of research on the prevalence of this type of heart block regarding the neonates and pediatr...
متن کاملSignificance of exercise-induced second degree atrioventricular block.
A case of second degree, type II, atrioventricular block precipitated by exercise is presented. It is suggested that exercise and other vagolytic manoeuvres may be used as a means of differentiating type I from type II atrioventricular block: the conduction disturbance of type I improves with exercise, whereas that of type II deteriorates with exercise.
