A non-invasive physiologic signs monitoring device includes a garment with electrocardiogram electrodes and various inductive plethysmographic sensors sewn, embroidered, embedded, or otherwise attached to the garment with an adhesive. The garment is in the form of a shirt. When the garment is fitted over the torso of the patient to be monitored, the electrodes and sensors generate signals in response to the physiologic signs of the patient. The signals are transmitted to a recording / alarm device where they are monitored for adverse conditions and logged. When an adverse condition or other preprogrammed condition occurs, a message is communicated to the patient by either an audio message or a display. The recording / alarm unit is also connectable to a remote receiving unit for monitoring by a health care professional or other machine.
