Hypothyroidism as the cause of atrioventricular block in an elderly patient.
Syncope is a common problem in the older patient. Sometimes syncope is caused by extreme bradycardia secondary to atrioventricular (AV) block. We describe a case in which a 90-year-old woman presented with complete AV block due to severe hypothyroidism. After suppletion with levothyroxine, AV conduction was restored. (Neth Heart J 2008;16:57-9.).
