Slide 1: The Electrophysiology of Coronary Artery Disease
The Electrophysiology of Sameney aneLy Disease MEASUREMENT AND ANALYSIS BY ELECTROCARDIOLOGY
Slide 2: Electrical conduction in the healthy heart
Electrical conduction in the healthy heart In a healthy heart, the activation wave- front enters the A-V node from the atria and is distributed from the Bundle of His through the Purkinje fibers and on to the ventricular myocardial cells. ‘These cells depolarize, producing the QRS complex on an ECG
Slide 3: Electrical conduction in the ischemic heart
Electrical conduction in the ischemic heart Ischemic, necrotic and fibrotic tissues exhibit abnormal onductive properties Ischemic cells may experience longer refractory periods or slower depolar zation rates Necrotic and fibrotic tissues are non-excitable. The activation wavefront follows constantl
Slide 4: Evolution of electrocardiographic morphology
Evolution of electrocardiographic morphology High-Frequency Components in the Electrocardiograms of Normal Subjects and of Patients with Coronary Artery angner, Jr, M.D., David B, Gesclowitz, Ph.D Mansure, M.D. b an expanded time scale for recording the electroca frequ in the QRS that do not appear
Slide 5: Clinical use of Variance Cardiography for the detection of CAD

Slide 6: Beat-to-Beat Morphology Variations at Different Phases of the ECG Complex
Beat-to-Beat Morphology Variations at Different Phases of the ECG Complex Shlomo A. Ben-Haim, M.D., DSe., Bruno Becker, M.D, Yeouda Edoute, M.D., Ph.D., Mira Kochanovski, M.D. Orly Azaria, B.Sc,, Elieser Kaplinsky, M.D., and Yoram Palti, M.D., Ph.D., American Journal of Cardiology 1991; 68:725-728,
Slide 7: Determination and measurement of variance in the QRS complex
Determination and measurement of variance in the QRS complex Templating All P-QRS-T cardiac cycles during a rest- are captured from ignals are amplified 650 times, digit i using a 16-bit analog-to- digital converter, and stored in memory for subsequent ycessing. A QRS tem- is are averaged to form 7
