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.
Stress can aggravate TMJ by causing overuse of jaw muscles when clenching or grinding teeth (like bruxism). But even if you arenât seeing signs of bruxism, you may still notice other symptoms of TMJ â such as jaw joint pain, popping and clicking of your jaw or inability to open and close your mouth easily.
