[Changes in the carotid sphymogram and apex cardiogram in the mesosystolic click-telesystolic apical murmur syndrome].

Synchronous records of ECG, PhCG, CSG and ACG were made of 25 patients with the syndrome of mesosystolic click-telesystolic apex murmur as well as of 62 subjects with healthy hearts. Mesosystolic retraction in CSG was found in 14 patients (57%) and incisura of the ACG systolic wave in 22 patients (88%). Similar changes were not established in the subjects with healthy hearts. The possibility of explanation of the changes found are discussed and those CSG and ACG changes are concluded to be useful as additional bloodless methods in the diagnosis of the syndrome of mesosystolic click-telesystolic apex murmur.
