Enlargement of the heart can be seen on ECG to a certain extent, but cardiac ultrasound can more accurately clarify the size of the heart.
Enlargement of the heart can be shown on ECG, for example, ECG P-wave with high sharpness and amplitude ≥0.25mV suggests right atrial hypertrophy, and P-wave widening >0.11s, often with a bimodal pattern suggests left atrial hypertrophy. High left ventricular voltage suggests left ventricular hypertrophy.
However, in order to clarify the specific size of the heart and the size of the atrioventricular cavity structure, as well as the heart’s systolic function and diastolic function is normal or not, the most intuitive examination is to rely on the cardiac ultrasound, which can completely and accurately understand the structural status of the heart.
Specific diagnosis and treatment should follow the doctor’s instructions.
