Prevalence and Magnitude of ST Segment and T Wave Abnormalities in Healthy Adult Subjects during Continuous Ambulatory Electrocardiography

  • P. Bjerregaard
Part of the Developments in Cardiovascular Medicine book series (DICM, volume 37)


From studies with ordinary ECG recording technique and multiple leads ST-T changes have been observed in relation to change in posture (Lachman et al. 1965), emotional strain (Sigler 1961), vagotonia (Iglesias et al. 1969), inhalation of tobacco smoke (Graybiel et al. 1936) and several other situations encountered by most subjects during an ordinary 24 hour period (Marriott 1959, Marriott 1967). Some of these changes have been observed. in precordial leads and must therefore occasionally show up during ambulatory ECG recording, where the most frequently used leads are “V5-like” with the exploring positive electrode at the V5 position and the negative electrode at various locations, but mostly at the manubrium sterni (lead CM5) or at the level of the fifth intercostal space in the right anterior axillary line (lead CC5).
