Abstract: A method of supplying medical screening services directly to a customer includes the steps of customer enrollment, electronic data collection and data transfer by the customer, data assessment by a screening service, and providing a report to the customer by the screening service. The report is made directly available to the customer by fax, by mail, by electronic mail, or by the Internet. Should a life threatening event be indicated by the assessment of the customer's data, the screening center will request emergency medical care for the customer. A recording device is sold to the customer either through telemarketing, direct mail, catalog sales, television, or retail outlets. The screening center has a cardiologist available to review the customer's ECG data upon the referral by a registered nurse.
