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.
When pain is always on your mind and you donât know when it will flare up next, it becomes a contributing factor for your stress. Other symptoms associated with TMJ such as tinnitus and migraines can also disrupt your peace of mind. Incidentally, stress can also cause or exacerbate TMJ symptoms and cause you headaches. Many people clench and grind their teeth during periods of stress, which can fatigue your jaw joint or cause a bad bite to form.
