Are patients' chief complaints generally specific to one organ system?
Patients' chief complaints and the resulting diagnoses are often within the same organ system. We found that a coordinator of care role for primary care physicians is appropriate for common neurologic, rheumatologic, and general complaints. A coordinator of care is not needed for specific specialty areas, including ophthalmology, dermatology, obstetrics/gynecology, urology, and otolaryngology, because patients typically can accurately self-refer to these specialists. Our study did not address reasons to use primary care physicians as coordinators of care, such as preventive care, patient preference, or cost effectiveness of care.
SCR events overcome source-sink mismatch to trigger PVCs at a critical CaSR threshold. Above this threshold, PVCs emerge due to increased probability and reduced variability in timing of SCR events, leading to significant diastolic depolarization. Sites of lower electronic load, such as the PS, are preferential locations for triggering.
