Here's a more concise and clear version of your question: --- "Hi, I recently stopped taking anxiety medication after 3 years and have been off it for 2 weeks. I've started using the WHOOP 4.0 band to monitor my health metrics, and I've noticed fluctuations in my HRV, ranging from 57 ms to as low as 37 ms, with a weekly average of 49 ms. Three months ago, I had blood tests, an ECG, and a 2D echo, all of which were normal. Given these HRV readings, should I be concerned or consider additional testing?"
