A 19-year-old man presents with recurrent episodes of palpitations and syncope. Vital signs show BP 118/76 mmHg, HR 92 bpm, RR 16/min, temp 37°C, SpO2 98% on room air. Resting ECG demonstrates a short PR interval (100 ms) and slurred upstroke of the QRS complex. Echocardiogram shows normal ventricular function with no structural abnormalities. He denies chest pain or dyspnea. Which of the following is the most likely diagnosis?
- A)Torsades de pointes
- B)Atrial flutter
- C)Wolff Parkinson White syndromeGABARITO
- D)AV nodal reentrant tachycardia
- E)Cardiogenic shock
Explicação
Wolff Parkinson White syndrome is correct. The short PR interval and delta wave indicate ventricular preexcitation through an accessory pathway that bypasses the AV node. These patients are prone to AV reentrant tachycardia and other supraventricular tachyarrh... Ver explicação completa e trilha adaptativa →
