چکیده
A 52 year old patient presented with orthostatic dizziness and syncope caused by postural heart block. When the patient was supine, atrioventricular conduction was normal but when she assumed the upright posture she developed advanced atrioventricular block rapidly progressing to complete heart block. We are presenting a case of syncope caused by orthostatic heart block.

Hypersensitive Carotid Sinus Reflex
A patient with transient, intermittent, complete heart block had periods of asystole, accompanied by syncope, whenever his cardiac rhythm shifted spontaneously from regular sinus rhythm to complete auriculoventricular dissociation. Similar clinical and electrocardiographic findings were produced by carotid sinus pressure when there was regular sinus rhythm. During the periods of heart block car...
متن کاملDysfunctional baroreflex regulation of sympathetic nerve activity in patients with vasovagal syncope.
BACKGROUND The interplay of resting muscle sympathetic nerve activity (MSA) and the baroreceptor reflex in patients with vasovagal syncope remains elusive. Hence, the aim of the present study was to investigate MSA, baroreceptor sensitivity, heart rate, and blood pressure under resting conditions and during orthostatic stress in patients with a history of vasovagal syncope. METHODS AND RESULT...

متن کاملCASE REPORT Swallow 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 کاملHypotensive bradycardic events during shoulder arthroscopic surgery under interscalene brachial plexus blocks
Sudden, profound hypotensive and bradycardic events (HBEs) have been reported in more than 20% of patients undergoing shoulder arthroscopy in the sitting position. Although HBEs may be associated with the adverse effects of interscalene brachial plexus block (ISBPB) in the sitting position, the underlying mechanisms responsible for HBEs during the course of shoulder surgery are not well underst...
