Heart palpitations are characterized by an unusually rapid or abnormal heartbeat that might be accompanied by other symptoms. Causes can range from a variety of physical contributions to sheer anxiety. Your heart contains it’s own electrical system and these abnormalities may signal a brief short circuit in the system.


  • Fluttering, flop or thump in the chest
  • Lightheadedness
  • Nausea
  • Sweating
  • Shortness of breath

Who is at risk?

Anyone will have an occasional abnormal heart beat, whether they are aware or not. Palpitations may be elicited by caffeine, nicotine, alcohol, diet supplements and many over the counter cold medicines. Illegal drugs, especially cocaine and amphetamines, are a prevalent cause. One organic cause may be an overactive thyroid. Severe heart disease and past heart attacks may predispose you to some of the more severe forms of abnormal heart beats.


Many episodes of palpitations are benign and may be addressed by carefully sorting out the potential cause of the irregular beats (such as too many cups of coffee) and then getting rid of that cause. More serious electrical abnormalities may require a very brief electrical shock or medication for correction. You must let a medical professional evaluate whether your palpitation is mild or serious. There are no home treatments for a serious case of irregular heart beat and you may be putting your life at risk by not having it promptly evaluated.

Emergency Warning Signs: When should I see a doctor?

If the patient experiences chest pain, breathing difficulty, weakness or numbness with palpitations or loses consciousness, call 911 immediately. If you experience a brief palpitation that might be related to caffeine, alcohol or medications you’ve ingested, call your primary care physician or come in to OnPoint Urgent Care for evaluation.

Treatment for less severe palpitations is available now at OnPoint Urgent Care in Aurora, Highlands Ranch, or Lone Tree Colorado.
