Learn to identify the warning signs, including rapid heartbeat, palpitations, shortness of breath, and more. Understand the causes, diagnosis, and treatment options for SVT, and take control of your heart health today.
Supraventricular tachycardia (SVT) is a type of abnormal heart rhythm, or arrhythmia, that occurs when the heart beats too quickly. It is a common condition that affects people of all ages, and its symptoms can vary from person to person. Understanding the common symptoms of SVT is crucial for seeking prompt medical attention and preventing potential complications.
SVT occurs when the heart's electrical system malfunctions, causing the heart to beat too rapidly. This can lead to a range of symptoms, some of which can be mild, while others can be severe. In this article, we will explore the 7 most common supraventricular tachycardia symptoms, their causes, and what to expect when seeking medical attention.
1. Rapid Heartbeat
A rapid heartbeat is the most common symptom of SVT. The heart rate can increase suddenly, often exceeding 100 beats per minute. This can feel like a pounding or racing sensation in the chest, and it may be accompanied by a feeling of anxiety or panic.
Causes of Rapid Heartbeat in SVT
The exact cause of SVT is not always clear, but it can be triggered by various factors, such as:
- Abnormal electrical pathways in the heart
- Stress or anxiety
- Caffeine or nicotine consumption
- Certain medications
- Hormonal changes
2. Palpitations
Palpitations are feelings of irregular heartbeats or skipped beats. People with SVT may experience palpitations, which can be uncomfortable and even frightening. Palpitations can occur at any time, even at rest, and may be more noticeable when lying down or engaging in physical activity.
What to Do If You Experience Palpitations
If you experience palpitations, it is essential to seek medical attention. Your doctor may recommend the following:
- Keeping a symptom journal to track when palpitations occur
- Avoiding triggers such as caffeine and nicotine
- Practicing stress-reducing techniques like meditation or deep breathing
- Undergoing further testing, such as an electrocardiogram (ECG) or echocardiogram
3. Shortness of Breath
Shortness of breath, or dyspnea, is another common symptom of SVT. This can occur when the heart is not pumping enough blood to meet the body's needs, leading to a feeling of breathlessness or suffocation.
Causes of Shortness of Breath in SVT
Shortness of breath in SVT can be caused by:
- Reduced cardiac output
- Increased heart rate
- Decreased blood pressure
- Respiratory problems, such as asthma or chronic obstructive pulmonary disease (COPD)
4. Chest Pain or Discomfort
Chest pain or discomfort is a symptom of SVT that should not be ignored. The pain can be mild or severe and may radiate to the arms, neck, or jaw.
Causes of Chest Pain in SVT
Chest pain in SVT can be caused by:
- Reduced blood flow to the heart muscle
- Increased heart rate
- Cardiac ischemia (reduced blood flow to the heart)
5. Lightheadedness or Dizziness
Lightheadedness or dizziness can occur when the heart is not pumping enough blood to the brain. This can be a symptom of SVT, especially if the heart rate is extremely rapid.
What to Do If You Experience Lightheadedness
If you experience lightheadedness or dizziness, it is essential to:
- Sit or lie down immediately
- Loosen tight clothing
- Avoid standing up quickly
- Seek medical attention if symptoms persist
6. Fatigue
Fatigue is a common symptom of SVT, especially if the heart rate is extremely rapid. This can lead to feelings of exhaustion, weakness, or lack of energy.
Causes of Fatigue in SVT
Fatigue in SVT can be caused by:
- Reduced cardiac output
- Increased heart rate
- Decreased blood pressure
- Anemia or other underlying medical conditions
7. Anxiety or Panic
Anxiety or panic can be a symptom of SVT, especially if the heart rate is extremely rapid. This can lead to feelings of fear, anxiety, or panic.
What to Do If You Experience Anxiety or Panic
If you experience anxiety or panic, it is essential to:
- Seek medical attention immediately
- Practice relaxation techniques, such as deep breathing or meditation
- Avoid triggers such as caffeine and nicotine
- Consider seeking counseling or therapy to manage anxiety
