Electrocardiographic Total 12-Lead QRS Voltage in Patients Having Operative Resection of Syphilitic Aortic Aneurysm

Electrocardiographic voltage has been used to determine the presence of left ventricular hypertrophy for about 70 years. Varying electrocardiographic criteria have been applied. We have found total 12-lead QRS voltage to be most useful in this regard. We measured total 12-lead QRS voltage in 24 pati...

Description
Summary:Electrocardiographic voltage has been used to determine the presence of left ventricular hypertrophy for about 70 years. Varying electrocardiographic criteria have been applied. We have found total 12-lead QRS voltage to be most useful in this regard. We measured total 12-lead QRS voltage in 24 patients in whom an ascending aortic aneurysm was resected and histologic study of its wall was classic of syphilitic aortitis. In these 24 patients total 12-lead QRS voltage ranged from 57 to 161 mm, averaging 120 ± 32 in the 11 men and 106 ± 24 mm in the 13 women. If normal 12-lead QRS voltage in adults is considered to be >175 mm not a single one of the 24 patients had normal voltage. Indeed, most were in the low normal area. Thus, this study provides some evidence via this indirect means that the heart itself is infrequently involved by syphilitic aortitis which produces an ascending aortic aneurysm of sufficient size to warrant resection.
