  • PODCAST: The PE ECG Finding Everyone Memorizes… But Gets Wrong

    Pulmonary embolism ECG findings are one of the most commonly tested Emergency Medicine board topics — and one of the easiest places to get tricked. Let's quickly cover what is the right answer on boards, and how in real life there is an even better option.

        • Presentation: 60-year-old male with a history of HTN and asthma.
        • EMS Findings: Severe respiratory distress, SpO₂ in the 60s on NRB, HR 120, BP 230/180.
        • Exam: Diaphoretic, diffuse crackles, warm extremities, pitting edema, and significant fatigue/work of breathing.
        • Pre-hospital meds: NRB, Duonebs, Dexamethasone, and IM Epinephrine (under the assumption of severe asthma/anaphylaxis).

          • Differential Diagnosis for the Hypoxic/Tachypneic Patient

          • Pulmonary: Asthma/COPD, Pneumonia, ARDS, PE, Pneumothorax, Pulmonary Edema, ILD, Anaphylaxis.
          • Cardiac: CHF, ACS, Tamponade.
          • Systemic: Anemia, Acidosis.
          • Neuro: Neuromuscular weakness.

            • What is SCAPE?Sympathetic Crashing Acute Pulmonary Edema (SCAPE) is characterized by a sudden, massive sympathetic surge leading to intense vasoconstriction and a precipitous rise in afterload.

            • Pathophysiology: Unlike HFrEF, these patients are often euvolemic or even hypovolemic. The primary issue is fluid maldistribution (fluid shifting from the vasculature into the lungs) due to extreme afterload.

              • Bedside Diagnosis: POCUS vs. CXRPOCUS is the gold standard for rapid bedside diagnosis.

              • Lung Ultrasound: Look for diffuse B-lines (≥3 in ≥2 bilateral zones).
              • Cardiac: Assess LV function and check for pericardial effusion.
              • Why not CXR? A meta-analysis shows LUS has a sensitivity of ~88% and specificity of ~90%, whereas CXR sensitivity is only ~73%. Importantly, up to 20% of patients with decompensated HF will have a normal CXR.

                • Management Strategy 1. NIPPV (CPAP or BiPAP)Start NIPPV immediately to reduce preload/afterload and recruit alveoli.

                • Settings: CPAP 5–8 cm H₂O or BiPAP 10/5 cm H₂O. Escalate EPAP quickly but keep pressures to avoid gastric insufflation.
                • Evidence: NIPPV reduces mortality (NNT 17) and intubation rates (NNT 13).

                  • 2. High-Dose NitroglycerinThe goal is to drop SBP to < 140–160 mmHg within minutes.

                  • No IV Access: 3–5 SL tabs (0.4 mg each) simultaneously.
                  • IV Bolus: 500–1000 mcg over 2 minutes.
                  • IV Infusion: Start at 100–200 mcg/min; titrate up rapidly (doses > 800 mcg/min may be required).
                  • Safety: ACEP policy supports high-dose NTG as both safe and effective for hypertensive HF. Use a dedicated line/short tubing to prevent adsorption issues.

                    • 3. Refractory HypertensionIf SBP remains > 160 mmHg despite NIPPV and aggressive NTG, add a second vasodilator:

                    • Clevidipine: Ultra-short-acting calcium channel blocker (titratable and rapid).
                    • Nicardipine: Effective alternative for rapid BP control.
                    • Enalaprilat: Consider if the above are unavailable.

                      • Troubleshooting & Pitfalls The “Mask Intolerant” PatientHypoxia is the primary driver of agitation. NIPPV is the best sedative. * Pharmacology: If needed, use small doses of benzodiazepines (Midazolam 0.5–1 mg IV).

                      • AVOID Morphine: Data suggests higher rates of adverse events, invasive ventilation, and mortality. A 2022 RCT was halted early due to harm in the morphine arm (43% adverse events vs. 18% with midazolam).

                        • The Role of DiureticsIn SCAPE, diuretics are not first-line.

                        • The problem is redistribution, not volume excess. Diuretics will not help in the first 15–30 minutes and may worsen kidney function in a (relatively) hypovolemic patient.
                        • Delay Diuretics until the patient is stabilized and clear systemic volume overload (edema, weight gain) is confirmed.

                          • Disposition

                          • Admission: Typically requires CCU/ICU for ongoing NIPPV and titration of vasoactive infusions.
                          • Weaning: As BP normalizes and work of breathing improves, infusions and NIPPV can be gradually tapered.

                            • Take-Home Points

                            1. Recognize SCAPE: Hyperacute dyspnea + severe HTN. Trust your POCUS (B-lines) over a “clear” CXR.
                            2. NIPPV Immediately: Don’t wait. It saves lives and prevents tubes.
                            3. High-Dose NTG: Use boluses to “catch up” to the sympathetic surge. Don’t fear the dose.
                            4. Avoid Morphine: Use small doses of benzos if the patient is struggling with the mask.
                            5. Lasix Later: Prioritize afterload reduction over diuresis in the hyperacute phase.

                              Diagnosing PE:

                              Step 1: Consciously consider the diagnosis

                              Step 2: Risk Stratify into low, intermediate, and high risk

                              Step 3: Choose appropriate testing based on pre-test probability

                              Classification of PE

                              1. High Risk/Massive PE: Hemodynamic Instability
                              2. Intermediate Risk/Submassive PE: Right Heart Strain without instability ; or PESI Class 3+
                              3. Low Risk/Non-Massive PE: Everything else (no instability, no heart strain, PESI Class 1-2)

                                4. Treatment of PE

                                1. High Risk/Massive PE: Thrombolytics and often thrombectomy
                                2. Intermediate Risk/Submassive PE: Heparin and sometimes intervention
                                3. Low Risk/Non-Massive PE: Either discharge with DOAC or admit with heparin
