Rapid, abnormal heart rate caused by dysfunction in the heart's upper chambers – known as Supraventricular Tachycardia (SVT).

Supraventricular Tachycardia (SVT) is a common heart rhythm disorder that originates above the ventricles, often exceeding 100 beats per minute. This condition can lead to serious complications such as heart failure or stroke, making it crucial to seek medical advice if experiencing symptoms.

SVT can be triggered by various factors, including emotional stress, physical stress, consumption of caffeine, alcohol, or certain medications, existing heart conditions, or the presence of abnormal electrical pathways. Hormonal changes, particularly in women, may also contribute to the onset of SVT, especially during pregnancy or menopause.

Common symptoms of SVT include palpitations, dizziness or lightheadedness, shortness of breath, chest pain, and fatigue. If you are experiencing these symptoms, it is essential to consult a healthcare professional.

Diagnosing SVT involves recognising symptoms, conducting an electrocardiogram (ECG), using Holter or event monitors, echocardiograms, and in some cases, electrophysiological studies. Treatment options for SVT include medication, ablation therapy, and in some cases, cardioversion or implantable devices. The choice of treatment depends on the type of SVT, its frequency, and the underlying causes.

There are several types of SVT, including Atrial Fibrillation, Atrial Flutter, and Paroxysmal SVT. The long-term outlook for individuals with SVT can vary widely based on several factors, including the underlying cause, frequency of episodes, and response to treatment.

Managing SVT symptoms involves lifestyle changes, medication, and in some cases, ablation therapy. Quality sleep is vital for heart health, and poor sleep can exacerbate SVT symptoms. Tips to improve sleep include establishing a routine, creating a relaxing environment, and avoiding screens before bedtime.

Stress management techniques like meditation, yoga, and deep breathing can help manage stress levels and reduce the risk of SVT episodes. Identifying and avoiding caffeine, alcohol, and stressors can help reduce the frequency of SVT episodes. Dietary changes, such as limiting caffeine and alcohol intake, staying hydrated, and maintaining a balanced diet, can also help manage SVT symptoms.

Regular ECGs and adjusting treatment plans based on symptoms and lifestyle changes are essential for managing SVT. Aerobic activities like walking, swimming, or cycling can be beneficial for individuals with SVT, but it's essential to consult a healthcare provider before starting any new exercise regimen. Regular follow-up appointments are essential to monitor the effectiveness of SVT treatment and make adjustments as needed.

Support groups and educational resources can provide valuable information and emotional support for individuals living with SVT. For most individuals with SVT, the prognosis is positive, with many experiencing a significant reduction in symptoms with appropriate treatment and lifestyle changes.
