Sinus Tachycardia: a Multidisciplinary Expert Focused Review.

Sinus tachycardia (ST) is ubiquitous, but its presence outside of normal physiological triggers in otherwise healthy individuals remains a commonly encountered phenomenon in medical practice. In many cases, ST can be readily explained by a current medical condition that precipitates an increase in the sinus rate, but ST at rest without physiological triggers may also represent a spectrum of normal. In other cases, ST may not have an easily explainable cause but may represent serious underlying pathology and can be associated with intolerable symptoms.

The differential impact of respiratory event scoring criteria on CPAP eligibility in women and men.

Study Objectives: Obstructive sleep apnea is more prevalent and severe in men than women. The American Academy of Sleep Medicine offers 2 definitions for scoring hypopneas: "acceptable" = associated with a ≥ 4% oxygen desaturation, adopted by Center for Medicare and Medicaid Services (CMS), and "recommended" = associated with a ≥ 3% oxygen desaturation and/or an arousal. We hypothesized that CMS vs American Academy of Sleep Medicine scoring criteria would differentially impact continuous positive airway pressure eligibility in women and men.

Massive hemorrhage after inspection bronchoscopy for carcinoid tumor.

Carcinoid tumor is a neuroendocrine tumor that can arise in the bronchial tree and can be hypervascular. Here we describe a case of bronchial carcinoid tumor in a 34-year-old previously healthy male who presented with hemoptysis and right lung mass. Inspection bronchoscopy revealed bronchus intermedius endobronchial lesion and was complicated by urgent intubation and placement of endobronchial blocker for massive hemorrhage.

High Interrater Reliability of Overnight Pulse Oximetry Interpretation Among Inexperienced Physicians Using a Structured Template.

Study Objectives: To assess the interrater reliability and accuracy of overnight pulse oximetry (OPO) interpretations by pulmonary fellows using a comprehensive structured template and after a brief educational session.

Methods: Using the template, four pulmonary and critical care (PCC) fellows interpreted OPO saturation waveforms and parameters extracted from 50 adult consecutive in-laboratory sleep studies. The template included three saturation parameters (mean saturation, oxygen desaturation index [ODI], and cumulative desaturation time) and description of the saturation waveform.

Pulmonary Hemorrhage following Edge-to-Edge Mitral Valve Repair.

Mitral valve repair with the MitraClip device has emerged as an effective treatment option for patients with severe mitral regurgitation and contraindications for surgical interventions. While the procedure is not known to cause pulmonary complications, we describe two cases of pulmonary hemorrhage following percutaneous mitral valve repair. The patients did well with supportive care and reinitiation of anticlotting agents was well tolerated after resolution of bleeding.
