ABSTRACT:
Hand-held apparatus for performing medical calculations includes a compact housing capable of being held within a hand of an operator. Provided in the housing is a data entry pad for selecting one of the medical calculations and entering data required for execution of the selected medical calculation, and a scanner and converter to input ECG waveforms as machine readable image data. A controller including a memory having the medical calculations stored therein is provided in the housing in communication with the data entry pad and the converter. The controller is configured to retrieve the selected medical calculation from the memory, provide prompts for entry of the data required for execution of the selected medical calculation, and provide a request for validation of each data entry made using the data entry pad. Included in the memory are medical calculations for calculating relevant measurements of the inputted ECG waveforms, including the PR Interval, the QRS Complex, the QT Segment, the ST Segment and the ventricular rate. The controller is configured to identify the start point and the end point of the relevant measurement and determine the difference therebetween. A display also is provided in the housing in communication with the controller to display each prompt for required data and each request for validation provided by the controller, as well as the data entries made and the results obtained.
