Take a look at this electrocardiograpy or ECG, and tell me your diagnosis.
This ECG is mine. I do not mean that it is in my collection. This is an ECG of my heart.
My diagnosis is left ventricular high voltage. Some consider it left ventricuar hypertrophy or LVH, but I recommend that a diagnosis of LVH be done when accompanied with ST-T chanages.
Echocardiography is considered in the case of LVH, but not always for left ventricular high voltage, given the sensitivity and specificity of ECG.
Maybe funny, but I have never checked my heart using echocardiography although I am a cardiologist.
