1. A non-transitory computer readable medium configured to store a plurality of programmatic instructions for processing data indicative of physiological parameters comprising:

  • code for receiving accelerometer data generated by an accelerometer device;

    code for analyzing the accelerometer data over a period of time, wherein the accelerometer data over the period of time is indicative of at least one of a number of steps taken by a wearer of the accelerometer device or a rate of the steps, and wherein the analyzed accelerometer data is indicative of a motion of the wearer;

    code for receiving physiological data generated by at least one physiological sensor used to monitor the wearer, wherein said physiological data has a time of occurrence associated therewith and wherein the physiological data comprises electrocardiogram (ECG) data and data indicative of the wearer'"'"'s pulse signal;

    code for correlating the analyzed accelerometer data with the time of occurrence of the ECG data to determine a degree of correlation;

    code for causing an alarm to issue if the ECG data, which are correlated with the accelerometer data, is indicative of an abnormal physiological condition; and

    code for suppressing said alarm, which is based upon the ECG data, if the accelerometer data correlated with the ECG data is indicative of a regular motion of the wearer;

    code for suppressing said alarm if the ECG data comprises noise above a threshold value and the pulse signal is indicative of a normal state;

    code for increasing a priority level of the alarm if the ECG data comprises ectopic beats and the pulse signal is indicative of a lower than normal pulse rate; and

    code for increasing a priority level of the alarm if the ECG data is indicative of an asystolic pause and the pulse signal is not received.
