Basis: 1, sinus tachycardia 2, left deviation of ECG axis 3, P wave broadening (it is recommended to check cardiac color Doppler ultrasound)

I asked you to do color Doppler ultrasound.

Mainly to rule out organic heart disease. Because the electric axis is left biased, the broadening of P wave indicates left ventricular hypertrophy.

The results of color Doppler ultrasound were normal without left ventricular hypertrophy.

So don't worry.

The left deviation of the electric axis can be seen in normal people.

P-wave broadening used to represent left atrial hypertrophy, but now it is basically not used. Because ECG is not as sensitive as color Doppler ultrasound in observing the anatomical structure of the heart, it is only meaningful when ECG indicates left atrial hypertrophy, which can be excluded or not by color Doppler ultrasound.
