This series consists of rolled electrocardiograms taken of various patients.

This series is formed of publications and other materials concerning various medical and history of medicine associations and organizations, including correspondence between Dr. Segall and others about such associations and organizations.

Referred to in Dr. Segall's "The evolution of the record system" as "Correspondence 1932-", the series contains papers relating to groups and societies in addition to personal correspondence.

This series consists of patient records started and/or consulted between 1939 and 1969, but not consulted after 1969. Each file is stored in a 4x6" envelope. Most of the files contain heart sounds diagrams drawn by Dr. Segall, 6x12'' clinical history forms, sections of electrocardiograms attached to dated cards, as well as 4x6" normal heart sounds record forms completed by Dr. Segall, which are often accompanied by sections of electrocardiogram readings. Many files also contain correspondence between Dr. Segall and other doctors, medical institutions, and health insurance companies, and occasionally correspondence between Dr. Segall and the patient and/or the patient's family.

This Series consists of ten drawers of a Kardex index, each of which is approximately 52 cm long. The top five drawers consist of indexed conditions, each of which is identified by a two or three character alphanumeric code (either A1 to A45, B1 to B99, or C1 to C70). Attached to each condition in the index is a list of the electrocardiogram numbers of particular patients. Dr. Segall seems to have determined that the listed electrocardiograms represent manifestations of their corresponding Kardex index condition. The individual electrocardiograms are located in Series G and are marked with their electrocardiogram numbers, the date on which they were created, as well as the names of the patients from which they were taken.

Drawers 6 through 10 of the Kardex index (Series M) contain indexed sections for 80 different cardiac symptoms. Each of the 80 symptoms are further divided into 10 (numbered 0 to 9) different sub-sections (possibly for different variations of each symptom), each of which contains a list of the electrocardiogram numbers, often, but not always, including the numbers for electrocardiograms of the patients whose files bear that particular two to three digit numerical code. The listed electrocardiograms seem to have been determined by Dr. Segall to represent manifestations of the corresponding Kardex index symptom.

According to the series descriptions found in Box 308, the series consists of five bundles of sheets summarizing the patient record details of the files contained in Series A.

This series consists of case history files of patients with mitral stenosis. Like most other patient files of the fonds, almost all of these files contain heart sounds diagrams drawn by Dr. Segall, 6x12" clinical history forms, sections of electrocardiograms attached to dated cards, as well as 4x6" normal heart sounds record forms completed by Dr. Segall which are often accompanied by sections of electrocardiogram readings. Many files also contain correspondence between Dr. Segall and other doctors, medical institutions, and health insurance companies, and occasionally correspondence between Dr. Segall and the patient and/or the patient's family.

Series contains case histories of Trans Canada Airlines and Ferry Command pilots. As Dr. Segall explains in "The evolution of the record system" (Box 308), the TCA and ferry command patient records were segregated in order to provide a collection of normal patterns of heart sounds from which he could develop a model pattern for heart sounds. This normal model pattern was then used as the standard against which he could compare the heart sounds of other patients.

Series contains extra copies of 68 clinical reports printed on Dr. Segall's stationary from the Medical Arts Building. Some of the reports contain sections of electrocardiograms in addition to other information.

Identified as "Office Files" in the series descriptions found in Box 308, this series consists of chequing records, cheque stubs, federal and provincial taxation records, daily record books (professional charges), donation records, bank deposit records, and account statements of Dr. Segall's practice. Box 469 also contains personal tax records circa 1982.
