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.
Pressure that comes from clenching causes teeth to flex at the gum line. This constant pressure against your teeth and gums can make gums recede and teeth become abfracted. Teeth can become sensitive or you may even get a toothache as a result of clenching. Other results of constantly flexed jaw muscles include jaw soreness, headaches, and a stiff or sore neck.
