Today, Medical Channels Union (MCU) launches a new group for cardiology enthusiasts;

🤓 Cardiology Cases is considering helping medical staff to become highly skilled in cardiology, particularly ECG interpretation.

🔗 https://t.me/Cardiology_Cases

🤝 We also welcome cardiologists from around the world to help us as group administrators.

A 40-year-old man is evaluated for palpitations in the emergency department. He has had these symptoms several times over the past year but this episode is worse. He denies any associated chest pain, lightheadedness, or syncope. He denies any history of medical problems and takes no medications. Examination reveals an adult male in no significant distress. Cardiac examination is significant for regular tachycardia with no jugular venous pressure elevation. Lungs are clear without crackles or wheezing. There is no lower extremity edema. ECG shown below. What is the best intervention at this point?


A. Valsalva maneuver
B. Adenosine
C. Metoprolol
D. Digoxin
E. Cardioversion

The correct answer is A.

Supraventricular tachycardias (SVT) include paroxysmal, reentry, or preexcitation tachycardias. Reentry SVTs include AV nodal reentry (AVNRT), atrioventricular reentry, or atrial reentry. Reentry circuits require the presence of at least two different conduction pathways with differential refractory times. It is characterized by an abrupt onset and termination of tachycardia, that distinguishes it from sinus tachycardia, which has gradual changes in rate. It is precipitated by a premature atrial or ventricular contraction or hyperadrenergic state. Other triggers include hyperthyroidism and stimulants, including caffeine, drugs, and alcohol. This patient has supraventricular tachycardia (SVT) likely related to atrioventricular nodal reentrant tachycardia (AVNRT) and he has no concerning symptoms.

The ECG shows a regular, fast rhythm with absent P waves and a narrow QRS complex. Unstable patients require immediate synchronized cardioversion. Stable patients, such as the patient above, should first undergo vagal maneuvers. Some common vagal maneuvers include holding your breath and bearing down (Valsalva maneuver), coughing, gagging, and immersing your face in ice-cold water. If vagal maneuvers are unsuccessful, adenosine is used both diagnostically and therapeutically. Adenosine transiently blocks the AV-node and allows the circuit to “reset.”


⚠Choice B is not correct:

Adenosine is very short acting and can be used if vagal maneuvers fail to terminate the arrhythmia.

⚠Choice C is not correct:

Metoprolol would also be considered if the above measures failed.

⚠Choice D is not correct:

Digoxin would also inhibit the AV node but has more potential side effects than the other medications and is rarely used for this purpose.

⚠Choice E is not correct:

Cardioversion would be reserved for hemodynamic instability including hypotension, heart failure, or angina.

Summarized Points:

This patient has SVT likely related to AVNRT and he has no concerning symptoms. The initial attempts at termination should use vagal maneuvers such as the Valsalva maneuver.

A 36-year-old life-long asthmatic has repeated episodes of asthma exacerbation accompanied by fever and thick brownish sputum that respond to oral prednisone therapy. His leukocyte count is 8,500/µL with 15% eosinophils. Chest x-ray reveals bronchiectasis on the left side. Which of the following is the best next step in the management of this patient?

A. Bronchoscopy with bronchoalveolar lavage
B. Immunoglobulin levels to evaluate for immunodeficiency
C. Induced sputum for Pneumocystis jirovecii
D. Purified protein derivative test
E. Aspergillus skin testing

This patient with known asthma has recurrent exacerbations with fever and expectoration of dark brown mucus, which is suggestive of allergic bronchopulmonary aspergillosis (ABPA). Patients may experience additional systemic symptoms (e.g., anorexia, malaise, or weight loss) or have hemoptysis. ABPA is caused by hypersensitivity to bronchial colonization by Aspergillus fumigatus. It occurs more commonly in asthmatics and patients with cystic fibrosis. Proteolytic enzymes and mycotoxins induce an intense inflammatory reaction that can eventually cause bronchiectasis and fibrosis. Early diagnosis is important as the onset of bronchiectasis is associated with poor outcomes. Diagnosis is based on clinical and radiographic features and immunologic testing. Immediate cutaneous hypersensitivity to skin prick testing is a characteristic finding. If negative, intradermal reactivity may be tested for confirmation. A negative skin prick test and intradermal reactivity excludes the diagnosis. If positive, immunologic testing is performed. High-resolution CT characteristically shows infiltrates, central bronchiectasis, and mucus-filled bronchi (mucoid impaction). A positive bronchodilator response on pulmonary function tests is only seen in about 50% of patients. Treatment involves a combination of corticosteroids and antifungal agents (e.g., itraconazole).

⚠ Choice A is not correct:

Bronchoalveolar lavage specimens may show Aspergillus species. However, the test is more invasive and is usually not indicated.

⚠ Choice B is not correct:

Common variable immunodeficiency (CVID) can present with recurrent pulmonary infections and bronchiectasis, but it does not cause recurrent asthma exacerbations responsive to steroids.

⚠ Choice C is not correct:

Induced sputum for Pneumocystis jirovecii may be helpful to diagnose Pneumocystis pneumonia in an asthmatic taking high-dose chronic oral steroids. However, this patient was only on intermittent steroids.

⚠ Choice D is not correct:

Patients with tuberculosis may also present with chronic cough and constitutional symptoms, but these are progressive (not intermittent) and do not respond to steroids.

Summarized Points:

Allergic bronchopulmonary aspergillosis is a hypersensitivity reaction to Aspergillus that may colonize the airways of patients with asthma and cystic fibrosis. It presents with worsening asthma symptoms, fever, fleeting infiltrates, pleuritic chest pain, and peripheral eosinophilia. The first step in diagnosis is Aspergillus skin testing. If left untreated, the disorder can result in bronchiectasis with a poor prognosis.
