An ECG monitoring system for ambulatory patients includes a battery-powered ECG monitor which attaches to a patient to receive patient electrical signals. A processor continuously processes received ECG signals and stores the signals in memory in the monitor. A wireless transceiver in the ECG monitor transmits the processed ECG signals to a cellphone handset. The battery of the monitor is recharged when the monitor is properly positioned in a charging dock, during which time the ECG signals are sent to the cellphone handset. Preferably the cellphone handset is recharged by the charging dock at the same time. At the conclusion of recharging and data transfer the monitor performs a self-test. A light on the charging dock is illuminated if any of the operations performed while the monitor is docked is unsuccessful.

An ECG monitoring system for ambulatory patients includes a small multi-electrode patch that adhesively attaches to the chest of a patient. A reusable battery-powered ECG monitor clips onto the patch and receives patient electrical signals from the electrodes of the patch. A processor continuously processes received ECG signals and analyzes the received ECG signals for pre-defined arrhythmia. If an arrhythmia is detected, a wireless transceiver in the ECG monitor transmits the event information and an ECG strip to a monitoring center. At the commencement of a monitoring procedure a message is sent to the monitoring center and configuration information for arrhythmia detection is down-loaded and installed in the monitor. The configuration file is determined by a screen of selectable standard and custom arrhythmias and alarm limits at the monitoring center.

A low pulsatility syringe pump including a duplex bearing set rotatingly supporting a lead screw, and a transmission having a first drive train configured to increase a number of motor rotations required for a single rotation of the lead screw, and a second drive train configured to reduce the number of motor rotations required for a single rotation of the lead screw as compared to the first drive train. Another embodiment also includes a motor configured to rotate the syringe about its own axis, independent of the motion of the lead screw. In this other embodiment, the fluid in the syringe barrel includes objects (such as cells, latex beads, etc.) entrained in the fluid. The rate of rotation (e.g., about three revolutions per second) is chosen such that each object traces a substantially circular pathway in the syringe barrel and remains in suspension.
