Ensuring ready access to health care remains a pressing concern in our increasingly fast-paced society, but the ever climbing costs of health care makes having health insurance or similar financial arrangements all but essential for practically everyone except the wealthy or destitute. For the insured, the average health insurance carrier effectively serves as the gatekeeper that controls entry into the health care system and who manages the provisioning or denial of health care by stipulating the terms under which benefits will be paid. Thusly, health insurance subscribers (or enrollees) are at times caught in the middle between the dictates of their insurer and their ability to readily address their health concerns. On the one hand, a subscriber who bypasses his primary care provider, as typically required by an insurer as a first contact, and instead seeks out a medical specialist on his own may be taking a financial risk, as a health insurer could deny coverage. On the other hand, the primary care provider may not always offer a satisfactory or practicable solution, particularly in situations where a condition has symptoms that are transient or infrequent, or which underlies a disorder with a long incubatory or onset period, as can happen with certain chronic conditions.
For instance, cardiac rhythm disorders may present with lightheadedness, fainting, chest pain, hypoxia, syncope, palpitations, and congestive heart failure (CHF), yet cardiac rhythm disorders are often sporadic in occurrence and may not show up in-clinic during a conventional 12-second electrocardiogram (ECG). Moreover, some types of cardiac rhythm disorders may warrant immediate subspecialist care, such as heart blockage, tachycardia and bradycardia, which require the attention of an electrophysiologist. Continuous ambulatory ECG monitoring over an extended period is more apt to capture sporadic cardiac events, yet health insurers often require a primary care referral to a monitoring laboratory before underwriting long-term ECG monitoring and access to a specialist may be delayed or denied, depending upon the ECG monitoring results.
Notwithstanding, if a subscriber's ECG could be recorded in an ambulatory setting over a prolonged time period, particularly for as long as seven days or more, thereby allowing the subscriber to engage in activities of daily living, the chances of acquiring meaningful medical information and capturing an abnormal event while the subscriber is engaged in normal activities are vastly improved. Unfortunately, few, if any, options for long-term ambulatory ECG monitoring that a subscriber could undertake on his own are available, and existing ECG monitoring solutions require physician involvement with tacit insurer approval. For instance, Holter monitors are widely used for extended ECG monitoring, typically for 24-48 hour time periods. A typical Holter monitor is a wearable and portable version of an ECG and, as such, is cumbersome, expensive and typically available for use only through a prescription, which limits their usability, and the discretion to refer the subscriber still remains with the attending physician.
Similarly, the ZIO XT Patch and ZIO Event Card devices, manufactured by iRhythm Tech., Inc., San Francisco, Calif., are wearable monitoring devices that are typically worn on the upper left pectoral region to respectively provide continuous and looping ECG recording. The location is used to simulate surgically implanted monitors. The ZIO XT Patch device is limited to a 14-day period, while just the electrodes of the ZIO Event Card device can be worn for up to 30 days. Both devices represent compromises between length of wear and quality of ECG monitoring. Moreover, both of these devices are also prescription-only, which limits their usability and, the same as a Holter monitor, the discretion to refer the subscriber remains with the attending physician.
Therefore, a need remains for a low cost monitor for recording an ECG and other physiology that can be used by an individual on their own, without health insurance pre-authorization, yet which can identify and generate an actionable, health condition-specific (and ideally health insurance-payable) referral to a medical specialist when medically appropriate.
