  2. 3 Lead ECG: Right Ventricular Hypertrophy (RVH)

    show more
    Description: Lead V1 show rSR' (with no widening of QRS complex), this is one of several ways RVH is exhibited in ECG, other forms of RVH manifestation on ECG include: Tall R in V1 + deep S in V6 Pure R wave in V1 qR wave in V1 Abnormal direction of T wave in right chest leads (normal T waves are downward in right chest leads in children; therefore upright T waves in V1-3 could indicate RVH. Lead II show tall P wave indicating right atrial enlargement (taller than 2 mm).

  4. Diagnostic algorithm: Pulmonary embolism

    show more
    Description: A diagnostic algorithm for pulmonary embolism (estimated frequencies of test results and associated prevalences of pulmonary embolism for a hypothetical cohort of 1000 outpatients) [1]. If a very sensitive D-dimer assay is used, it can be the first test performed: a negative result excludes pulmonary embolism regardless of clinical assessment category and a positive test can be followed by a ventilation–perfusion scan [2]. A ventilation–perfusion scan can be performed as the initial test without using clinical assessment of the probability of pulmonary embolism as part of the diagnostic process [3]. Pulmonary angiography or helical CT may be considered if the clinical assessment of pulmonary embolism probability is low, particularly if a D-dimer test has not been done [4]. Additional testing (e.g., helical CT, bilateral venography) may be considered if overall assessment suggests a high probability of pulmonary embolism (e.g., 50%–80%), symptoms are severe or cardiopulmonary reserve is poor [5]. Venography should be considered if there is an increased risk of a false-positive ultrasound result (e.g., previous venous thromboembolism, equivocal ultrasound findings, preceding findings suggest low probability of pulmonary embolism [e.g., ≤ 10%]) [6]. It is reasonable not to repeat ultrasound testing, or to do only 1 more ultrasound after 1 week, if preceding findings suggest a low probability of pulmonary embolism (e.g., ≤ 10%) [7]. If helical CT is used in place of ventilation–perfusion lung scanning: (i) intraluminal filling defects in segmental or larger pulmonary arteries are generally diagnostic for pulmonary embolism; (ii) all other findings (i.e., a normal CT scan or intraluminal filling defects confined to the subsegmental pulmonary arteries) are nondiagnostic and can be managed as shown for a nondiagnostic lung scan.

  5. 12-Lead ECG: Chronic Obstructive Pulmonary Disease (COPD)

    show more
    Description: Sinus tachycardia (107 bpm), peaked P waves in leads II, II, aVF and V1 (P pulmonale), right access deviation, and delayed precordial transition zone in which the net QRS does not become positive until lead V5. Nonspecific ST-T abnormalities are also present. Although not seen here, patients with COPD often have low voltage in the limb leads
