title: Complete AV heart block during acute silent myocardial infarction detected only by myocardial perfusion scintigraphy.
abstract: Seven patients with complete AV heart block and wide QRS complexes, atypical chest pain and no specific serum enzymes modifications for myocardial necrosis are reported. The patients showed no prior complete AV heart block although myocardial perfusion scintigraphy showed localized uptake demonstrating a small area of acute myocardial necrosis. These cases may be described as "true silent" acute myocardial infarction which could not be clinically recognised without Technetium pyrophosphate scintigraphy.
