20150073490 | SYSTEM AND METHOD FOR USING DIAGNOSTIC PULSES IN CONNECTION WITH DEFIBRILLATION THERAPY - An external defibrillator system is disclosed that generates and applies a diagnostic signal to the patient in conjunction with defibrillation therapy. The diagnostic signal is designed to elicit a physiologic response from the patient's heart, namely, mechanical cardiac response and electrical cardiac response, electrical cardiac response only, or no cardiac response. Depending upon the type of cardiac response detected, the system selects an appropriate resuscitation protocol that considers the likely responsiveness of the patient to defibrillation therapy. In one practical embodiment, a stimulus signal is applied to patients that show mechanical and electrical capture in response to the diagnostic signal. The stimulus signal maintains the mechanical capture (and, therefore, perfusion) for a period of time prior to the delivery of a defibrillation pulse. | 03-12-2015 |

20100010358 | System and Method For The Detection of Acute Myocardial Infarction - A system and method are provided for the detection of acute myocardial infarction (AMI) using a staged approach for accurate and rapid detection. Physiological signals in a patient's body are sensed and corresponding physiological parameters are derived in a staged approach in order to determine the probability that AMI is occurring in a patient in a first detection stage. If the computed probability from physiological signals indicates the possibility of AMI, then the patient is prompted, such as through a patient-wearable device, to answer specific AMI-related questions to assist in diagnosis of AMI in a second stage. AMI is detected when the computed probability in the second stage exceeds a predefined detection threshold. A patient or physician alert may then be generated, which may further include the transfer of data via a communication link or network, in response to an AMI detection signal. | 01-14-2010 |

Once a desired level of probability that the heart-related condition has been detected exists, data utilized in the analysis can be transmitted remotely for clinical review and confirmation of the device's detection of the condition. The patient may be prompted to answer questions related to symptoms that patient is experiencing through an input device in order further confirm the probability that the condition is occurring in the patient. | 01-14-2010 |
