Significance 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.
متن کاملExercise-Induced Intranodal Atrioventricular Block
Exercise-induced atrioventricular (AV) block in patients with normal AV conduction at rest is rare. Herein, we describe the case of a 67-year-old woman with normal 1 : 1 AV conduction at rest, who developed complete AV block during a treadmill test. Our patient complained of effort-related dizziness and dyspnea, which had been ongoing for 3 months. The patient's physical examination was normal....
متن کامل[High-degree atrioventricular block induced by Prinzmetal angina].
We present the case of a 46-year-old woman with episodes of chest pain with ST-T segment elevation and paroxysmal high-degree atrioventricular block and syncopal episodes. Coronary angiography revealed no significant atheromatous lesions. The patient was treated with nitrates and calcium channel blockers but syncopal episodes with atrioventricular block persisted. A DDD-R pacemaker was implante...
متن کاملSecond-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...

To cite: Akhtar W, Rathod KS, Alexander J, et al. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013010474 DESCRIPTION We present a case of profound first-degree heart block with the longest reported PR interval (640 ms). The aetiology of extreme first-degree block in our case was multifactorial, due to senile conductive system fibrosis, hypothermia and digoxin ...
