Treatment of Dizziness, Palpitations, & Disturbances of the Heart Rhythm

Disturbances of heart rhythm happens when the normal electrical impulses that cause the heart to beat are interrupted. Supraventricular tachycardia (SVT) is a rapid heartbeat that begins above the heart’s lower chambers. The most common cause occurs when a "short circuit" causes electrical impulses to circulate in a merry-go-round-like cycle that takes over the heart's normal rhythm.

The most common type are heart palpitations—a feeling of a racing heart or fluttering or pounding in the chest. Other symptoms include:

  • Dizziness

  • Shortness of breath

  • Chest pain

  • A pounding sensation in the throat or neck

  • Weakness

  • Fatigue

  • Lightheadedness

  • Fainting (especially in the case of underlying heart disease)

At HeartCare we will take a complete medical history to determine if your symptoms might indicate SVT. Heart palpitations are among the most common symptoms of many types of SVT. However, changes in heart rate can occur under normal circumstances without any underlying disease. That’s why it’s important to explain your symptoms in as much detail as possible. For example, be prepared to discuss:

  • When your symptoms began

  • How long they last

  • Whether or not they stop and start or continue all the time

  • Whether or not any particular activity, such as physical exercise, brings on or worsens symptoms

  • Whether any activities relieve symptoms, including holding your breath or lying down

  • If your family has a history of heart disease

  • If you have been diagnosed with heart disease or any other illnesses

During your physical examination at HeartCare your doctor will be able to detect any factors that may be worsening your symptoms, and also determine your risk for possible complications.

Your thorough examination will also include an electrocardiogram (ECG) and laboratory tests such as a complete blood count may be conducted to rule out or confirm other contributing illnesses such as anemia, hyperthyroidism, or metabolic disturbances.

Your doctor may want to confirm the results of your ECG with an event recorder or Holter monitor. An event recorder is used if your doctor suspects that you have occasional arrhythmias. Like an ECG, an event recorder records electrical impulses as they pass through different stages of a heartbeat. Your doctor may conduct an exercise stress test if he or she suspects that your tachycardia is related to physical activity. Exercise testing involves walking on a treadmill or pedaling an exercise bicycle at various speeds and levels of intensity while your doctor measures your heart rate, rhythm, and blood pressure.

If the doctor suspects underlying heart disease, he or she may take a chest x-ray. A chest x-ray is usually reserved for people with symptoms—such as shortness of breath or chest pain—that are related to diseases that affect the heart structures. The x-ray can show calcium deposits, which can lead to valve disease, scarred muscle tissue, or blocked arteries. In addition, a chest x-ray can be used to learn if there is fluid in the lungs, which indicates congestive heart failure (a condition in which the heart cannot pump an adequate amount of blood) or lung problems.
