Hello marissabrownn Welcome to HCM Yes you are right its part of anxiety, mostly anxiety disorders presents with rapid heart rate or palpitations, sweating, chocking sensation in throat, epigastric emptiness, tremors, shaking, dizziness, and other gastric problems. If its happening 4-5 times a week kindly do not ignore. You can try deep breathing exercises, progressive muscle relaxation techniques, yoga or meditation at home. (you can google for details) If not controlled by these methods then visit a psychiatrist (medicines as benzodiazepines, SSRI are very effective) hope I solved your query. Take Care
