1. A system for measuring vital signs and motion from a patient, comprising:
(a) a first module comprising a housing configured to be worn on the chest of the patient and an electrocardiogram (ECG) circuit and a three axis accelerometer contained within the housing, wherein (i) the ECG circuit is in electrical communication with at least three ECG leads and generates therefrom a time-dependent digital ECG waveform for each of the ECG leads and transmits the resulting time-dependent digital ECG waveforms as network packets comprising a header portion that indicates the origin of the packet, and a data portion, and (ii) the three axis accelerometer generates a time-dependent digital motion waveform for each of the three axes and transmits the resulting time-dependent digital motion waveforms as network packets comprising a header portion that indicates the origin of the packet, and a data portion; and
(b) a processing component comprising a housing configured to be worn on the patient's lower arm and a microprocessor and a serial transceiver within the housing and a display on a surface of the housing, wherein the processing component is configured to communicate with the first module to receive the network packets containing the time-dependent digital ECG waveforms and the network packets containing the time-dependent digital motion waveforms;
wherein the processing component communicates with the first module to transmit a timing synchronizing packet that is received and used by the first module to time-synchronize the network packets containing the time-dependent digital ECG waveforms and the network packets containing the time-dependent digital motion waveforms for processing by the processing component such that there is a maximum 40-microsecond timing error in the synchrony between the time-dependent digital ECG waveforms and the time-dependent digital motion waveforms, and
wherein the processing component is configured to display the time-dependent digital ECG waveforms and a motion state determined using the time-dependent digital motion waveforms on the processing component display.
