Multiple-Lead Exercise Electrocardiography
A svstem of miultiple-lead exeicise electrocardiography has been applied to the study of 107 normal subjects and 67 patients with angina pectoris. The results of this test are compared to those of coronary cinearteriography in 84 patients. In-exercise ECGs gave useful additional information in 59% of the angina patients but were essential for interpretation in 9%. It added considerably to the s...
متن کاملReliability of single-lead and multiple-lead electrocardiography during and after exercise.
To define the number, type, and criteria for interpretation of elecfrocardiographic leads yielding the most reliable results during and after exercise, 203 men were studied. Twelve-lead exercise electrocardiograms (including lead CM5) and coronary arteriograms were correlated. Depression of the S-T segment that was present only during exercise was of doubtful significance. Analysis of ECGs afte...
متن کاملImprovements in exercise electrocardiography.
In 1908, Einthovent published the first example of normal electrocardiographic responses to exercise. In 1928, Feil and Siegel2 observed abnormal downsloping ST depression and T wave inversion in three of four patients experiencing anginal attacks (presumably after climbing stairs to the phy-sician's office; H. Hellerstein, personal communication). In 1932, Goldhammer and Scherf3 associated thi...

situation resembling most electrophysiological studies. One other factor in favour of subpectoral automatic cardioverter/defibrillator implantation under local anaesthesia is the reduced complexity of the implant procedure, whereby the procedure-related risk for the patients is reduced, since the complication rate during a pacemaker-like approach of automatic cardioverter/ defibrillator implant...
متن کاملLead Field Scalar and Loop Spatial Electrocardiography
Spatial electrocardiography based on the lead field concept of McFee and Johnston appears to be theoretically more satisfactory than other systems of vectorcardiography. To determine the normal range of planar loop patterns to be expected with this technic and to compare them with those derived by previous methods, a survey of young adult males has been carried out with particular reference to ...
