Echocardiography Right ventricular function can be assessed using several methods and echocardiography is generally the first‐line tool (Figure 1). TAPSE is most frequently used and has an independent prognostic value in HFpEF.4, 8, 23-25 The currently recommended lower limit cut‐off for TAPSE is <17 mm,12 although prior studies frequently used <16 mm. Fractional area change (with a lower limit of normal <35%12) is also commonly used, and is predictive of all‐cause mortality and heart failure hospitalizations in HFpEF. #Diagnosis #Cardiology #POCUS #Echocardiogram #RightVentricle #RightVentricular #RVDysfunction #Measurements #Criteria

Venn Diagram - Does this patient have pneumonia? Diagnosis is generally based on three lines of evidence: - Imaging evidence of a chest infiltrate (e.g., CXR, CT, ultrasound) - Inflammation (e.g., fever/hypothermia, rigors, night sweats, leukocytosis, left-shift, procalcitonin) - Pulmonary symptoms (e.g., dyspnea, cough, sputum production, pleuritic chest pain) and signs (tachypnea, hypoxemia). #Pneumonia #Venn #Diagram #Diagnosis #Pulmonolary

Algorithm for the diagnosis of hyponatremia. If you start with the osmolalities, urinary sodium etc first and leave the fluid status assessment til the end you are more likely to make a correct diagnosis - this is because fluid status assessment is unreliable even when perfomed by experienced doctors and has poor interrater agreement. #Diagnosis #Hyponatremia #Differential #Algorithm #Osmolality #management
