Probable hypertrophic cardiomyopathy [150 ECG]

Cho điểm
Probable hypertrophic cardiomyopathy
This ECG was recorded as part of a routine examination of a healthy 25-year-old professional athlete. There were no abnormal physical findings. What does it show and what would you do?



ANSWER 98

The ECG shows:
• Sinus rhythm, average rate 44/min
• Normal axis
• Normal QRS complexes, apart from narrow Q waves in lead VL
• Marked T wave inversion in leads I, VL, V2–V6
Clinical interpretation
If this ECG had been recorded from a middle-aged man presenting with acute chest pain, the diagnosis would be an anterior non-ST segment elevation myocardial infarction. The ECGs of athletes can show ST segment and T wave changes due to left vent ricular hypertrophy, but anteroseptal T wave inversion of this degree in a healthy young man almost certainly represents hypertrophic cardiomyopathy.

What to do
Echocardiography will confirm the diagnosis. Ambulatory ECG recording will show whether the patient is having ventricular arrhythmias. He must not play competitive sports, and his close relatives should be screened.

Summary
Probable hypertrophic cardiomyopathy.
