Detailed Answer:
Hello!

Welcome on HCM!

Regarding your concern, I would like to explain that first it is necessary to exclude a measurement artefact leading to absence of a BP reading on the left arm.

To overcome this problem it is necessary to investigate the presence of arterial pulse over the radial artery (located over the lateral part of the wrist).

Also an exact BP measurement equipment should be applied.

If no pulse and blood pressure readings are present, especially if associated symptoms occur (chest or pain, etc.), then you need to reconsult immediately the doctor to exclude a possible aortic or left arm artery disorder.

Hope to have been helpful to you!

Feel free to ask me whenever you need!

Greetings!
