A system for monitoring the heart of a patient. The system is comprised of a remote station having a device for generating an electrocardiogram of the patient, a device for detecting predetermined cardiological events in the patient in communication with the generating device and a transmitter for transmitting the electrocardiogram. The system also is comprised of a central station in continuous communication with the transmitter for receiving the transmitted electrocardiogram when a predetermined cardiological event occurs. There is also a database in communication with the central station for storing patient data and providing patient data to the central station. Additionally, there is a display device in communication with the central station and the database for displaying the patient data and the transmitted electrocardiogram. A method of monitoring the heart of a patient. The method includes the first step of taking an electrocardiogram of a patient at a remote station. Then, there is the step of automatically detecting predetermined cardiological events in the electrocardiogram. Next, there is the step of transmitting the electrocardiogram to a central station along with identification of the patient if a predetermined cardiological event occurs and immediately after it occurs. Then, there is the step of retrieving data about the patient from a database in communication with the central station. Next, there is the step of transmitting the patient's data to the central station.

Method and system for monitoring the heart of a patient

The present invention pertains to a system for monitoring the health condition of a patient, such as the condition of the patient's heart. The system comprises a patient station having means for monitoring a predetermined bodily function of the patient and a patient transmitter for transmitting information relating to the bodily function. The system is also comprised of a secondary system remote from the patient at the patient station having means for activating the patient station such that information relating to the monitored bodily function can be transmitted from the patient station to the secondary station. The secondary station is in communication with the patient station. The present invention also pertains to a method of monitoring the health condition of a patient. The method comprises the steps of providing the patient with a device for monitoring a predetermined bodily function of the patient at a patient station. Then there is the step of activating the patient station from the secondary station remote from the patient at the patient station such that information relating to the predetermined bodily function of the patient can be transmitted to the secondary station.

A method and apparatus for processing electrical signals by modifying delta modulation to discrete slope delta modulation includes converting its electrical signals into compressed digital information, and representing this digital information as a sequence of slops or deltas added to the past value of the representation. For each sample period, a slope is chosen from slope tables having multiple entries and each choice is represented by a Huffman code. Signal compression occurs in two steps: first the selection of a small number of possible slopes provides compression and also the most probable slopes are represented by the shortest Huffman codes providing additional compression. Depending on the history of the slope chosen, multiple tables can be accessed with different slop entries. Two check point values are provided which code absolute output levels instead of slopes in order to facilitate recovery of the signal in the event of transmission errors. Initial matching of a specific slope value sought in the same table wherein the next preceding value was found. In one embodiment, at least four slope tables each having at least four values is employed. The apparatus has components for performing the method.
