Rapid Heart Beat in Cats. Save to mypetMD. Supraventricular tachycardia (SVT) is a medical condition that is characterized by a rapid heart rate that occurs during times of rest or low activity (i.e., at times other than exercise, illness, or stress).
If you chew too much or subconsciously clench your jaws during stressful times, your jaw muscles can spasm and cause pain. Stress-induced clenching or grinding can cause slight misalignment of the jaw, leading to jaw, neck, or eye pain, as well as jackhammer-like headaches.
It seems strange to think that something that affects a joint in the jaw can lead to anxiety, but TMJ is actually a fascinating disorder, and causes a host of different symptoms that can lead to the development of anxiety. However, it should be noted that TMJ often doesn't cause anxiety-instead, it makes anxiety worse.
