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.
Exercises that help you relax can also help to relieve TMJ pain â especially if it's stress-related. Mayo Clinic recommends breathing exercises to ease tension in the jaw muscles. If you are feeling tense, try inhaling for a count of five or 10, then slowly exhaling.
