Patient screening tools for implantable cardiac stimulus systems
First Claim
1. A patient screening device for use in determining whether a patient is well suited to receiving an implantable cardiac device (ICD) having a first configuration, the patient screening device comprising:
- a user interface allowing for user input and display of information to a user;
inputs for coupling to a plurality of cutaneous electrodes; and
operational circuitry configured to emulate filtering and detection characteristics of the ICD of the first configuration;
wherein the operational circuitry is configured to perform a method comprising;
capturing data via the inputs from coupled cutaneous electrodes placed on a patient;
emulating the filtering and detection characteristics of the ICD of the first configuration, including applying a beat detection method that would be used by the ICD of the first configuration;
determining whether the ICD of the first configuration can accurately analyze cardiac data from the patient and;
if the ICD of the first configuration can accurately analyze cardiac data from the patient, determining that the patient is well suited to receiving the ICD of the first configuration;
or,if the ICD of the first configuration is not likely to accurately analyze cardiac data from the patient, determining that the patient should not receive the ICD of the first configuration.

Abstract
Tools and devices are provided for determining whether a patient is well suited to receiving an implantable cardiac stimulation device by analyzing cardiac signals captured using external or cutaneous electrodes. Some of the illustrative tools include shapes for visual comparison to printed ECG strips. Kits for use of illustrative tools are also shown. Automatic devices are also disclosed which perform at least some analytical functions electronically for a user. In an example, a printed ECG strip is visually compared to a shape in order to ensure a patient is well suited to receiving a cardiac stimulation device having a particular implant location and/or cardiac signal analysis method implementation.
