Tachycardia

Tachycardia means that the heart beats faster than normal – usually over 100 beats per minute at rest. It can feel like strong palpitations or a racing heart, and in some cases, it can affect blood flow in the body.

Common symptoms of tachycardia

  • Pulsed and rapid pulse
  • Feeling faint and dizzy
  • Increased shortness of breath, especially with exertion
  • Chest discomfort or chest pain
  • Feeling weak and tired

These symptoms can come on suddenly and go away quickly, but they can also be persistent.

How is tachycardia tested?

To find out the cause of tachycardia, a:

  • ECG (electrocardiogram) – records the electrical activity of the heart
  • Long-term ECG or Holter ECG – used for temporary symptoms
  • Exercise test – ECG performed during physical activity load
  • Blood tests – to rule out underlying causes such as metabolic disorders such as thyroid disorders and diabetes
  • Echocardiography (ultrasound of the heart) – to assess the function and structure of the heart

Treatment of tachycardia

Treatment of tachycardia is adapted to the cause and severity of symptoms:

  • Lifestyle changes – reduce stress, caffeine and alcohol intake and smoking
  • Medications – for example, beta-blockers that slow the heart rhythm can be added
  • Electrical cardioversion – this is an electrical impulse that restores the normal rhythm of the heart
  • Ablation – a minor procedure that involves "burning away" the areas in the heart that causes incorrect signals
  • Pacemaker or ICD – in some cases where the rhythm disturbance is severe and recurrent

When should you seek medical attention?

You should seek medical attention if you experience recurrent palpitations, especially if you also feel dizzy, have chest pain or faint. Tachycardia can sometimes be a sign of an underlying heart problem that needs to be investigated.

Questions and answers

Tachycardia is defined as a resting heart rate that consistently exceeds 100 beats per minute.

Doctors use ECGs (standard or long-term Holter monitors), stress tests to see how the heart reacts to exercise, and blood tests to rule out issues like thyroid dysfunction or diabetes.

You should seek medical attention if you experience recurring palpitations, especially if they are accompanied by chest pain, fainting, or severe dizziness.

With us, you will always receive a doctor’s opinion from a licensed physician when you order a medical check-up that includes a medical opinion. The doctor’s opinion includes an overall assessment of your results from laboratory analysis. The opinion is individual and may vary depending on the specific tests your medical check-up includes.

What can I expect in the medical report?

The medical opinion will summarize the results of your test results to give you an assessment of your health including any abnormalities outside the reference ranges. In case of abnormalities or need, your doctor may also contact you for a free conversation to explain and talk about your results. Remember that a health check always includes specific test results based on your health and your personal circumstances. Values outside the reference range should therefore always be discussed with a doctor before any decisions regarding possible treatment are made.

What does the doctor look at during a health check?

When assessing a blood test or health check, your doctor will look at several different parameters to evaluate your health and identify any abnormalities. Below are some common aspects your doctor may examine:

Blood counts: Your doctor will check red, white and platelet counts to identify any signs of anaemia, infection or bleeding.

Nutrients and biochemical markers: Includes, for example, analysis and monitoring of blood sugar (glucose) levels, electrolyte levels (e.g. sodium, potassium), liver function tests (e.g. liver enzymes), kidney function tests (e.g. creatinine, urea) and lipid profile (e.g. cholesterol, triglycerides). The results of the tests give your doctor a better idea of your organ function, blood sugar level, cholesterol conditions and other important health aspects.

Inflammatory markers: Your doctor may measure health markers such as C-reactive protein (CRP) or red blood cell decrease rate (SR) to evaluate inflammatory conditions or confirm an active infection.

Hormone levels: Your doctor may monitor your hormone levels to assess hormonal imbalances or diseases, such as thyroid hormones (TSH, T3, T4), sex hormones or other specific hormones such as testosterone levels.

Specific tests: Depending on your goal of your health check or medical history, your doctor may look into specific tests to investigate conditions or diseases, such as diabetes, vitamin deficiency or autoimmune diseases.

In conclusion, the doctor weighs all test results based on the health check to assess your overall health, detect any abnormalities and identify possible underlying medical conditions.

What happens if I have abnormal test results?

If your blood count is abnormal, this will be addressed in your personal medical opinion. Depending on the nature and extent of the abnormality, your doctor may also contact you directly through the test result service for further guidance. Various measures and advice will be provided based on the specific abnormalities observed along with your medical history.
