Syncope and paroxysmal atrioventricular block
Current literature reveals three types of paroxysmal atrioventricular block (AVB) that can cause syncope: Intrinsic paroxysmal atrioventricular block is due to an intrinsic disease of the AV conduction system; this type of "cardiac syncope" is also called Stokes-Adams attack; Extrinsic vagal paroxysmal atrioventricular block is linked to the effect of the parasympathetic nervous system on cardi...
متن کاملSyncope Due to Idiopathic Paroxysmal Atrioventricular Block
Results The study group consisted of 9 men and 9 women, mean age 55 19 years, who had recurrent unexplained syncope for 8 7 years and were subsequently followed up for as long as 14 years (4 4 years on average). The patients had no structural heart disease, standard ECG was normal, and electrophysiological study was negative. In all patients, prolonged ECG monitoring documented paroxysmal compl...
متن کاملSyncope and Idiopathic (Paroxysmal) AV Block.
Syncope due to idiopathic AV block is characterized by: 1) ECG documentation (usually by means of prolonged ECG monitoring) of paroxysmal complete AV block with one or multiple consecutive pauses, without P-P cycle lengthening or PR interval prolongation, not triggered by atrial or ventricular premature beats nor by rate variations; 2) long history of recurrent syncope without prodromes; 3) abs...
متن کاملSwallow syncope associated with complete atrioventricular block and vasovagal syncope.
A 21 year old man presented with multiple, recurrent episodes of complete atrioventricular (AV) block associated with swallowing. Electrophysiological study revealed an AV block with swallowing of carbonated beverages and balloon inflation in the lower oesophagus. Evaluation did not demonstrate any underlying oesophageal or cardiac disease, and the AV block was not induced after intravenous atr...
متن کاملSyncope due to paroxysmal complete atrioventricular block in a patient with aortic valve stenosis.
A 66-year-old man was admitted due to repeated syncope, and the electrocardiogram showed complete atrioventricular block (CAVB). He had moderate aortic valve stenosis (AS) with a severely calcified valve. This case indicates that if calcification spreads into the cardiac conduction system, it may cause CAVB. Although CAVB is not typically considered a main cause of syncope in AS patients, it sh...
