The prognosis for SVT is very good as it is a manageable condition that doesn't usually cause dangerous cardiac symptoms or cardiac arrest. However, it can cause unpleasant symptoms that we treat with catheter ablation or medications. To learn which treatment is most appropriate for you, book an appointment with Dr Syed Ahsan.

Outlook for SVT is very good. It's a condition that causes symptoms but tends not to be dangerous or cause cardiac arrest. And nowadays, we can fix this for you.

Video Description

Dr Syed Ahsan explains that SVT is very rarely fatal or dangerous. However, it can cause a heart attack in severe cases and syncope (fainting), which may lead to related injuries. Wolff-Parkinson-White (WPW) syndrome, a condition that causes SVT, carries an extremely small risk of sudden cardiac death (SCD). People with symptomatic WPW have a slightly higher risk of SCD than those that are asymptomatic. Contact our clinic to discover the severity of your condition and the best way to treat it.

It's very rare for SVT to be fatal. One condition known as Wolff-Parkinson-White syndrome carries a very, very small risk of sudden cardiac death.

Dr Syed Ahsan details the simple techniques that may help you stop SVT symptoms, such as breathing exercises (the Valsalva manoeuvre) and cold water. Your diet and exercise regime can also help you avoid SVT episodes. Read our blog to learn more: Lifestyle changes to help manage arrhythmia.

So there are some really simple techniques. These are called- known as a Valsalva manoeuvre. And these involve breathing exercises or using cold water, and your heart specialist can talk you through these in a bit more detail. But these can often be used to terminate the SVT at home.

Dr Syed Ahsan explains that you may feel dizzy, experience shortness of breath, or even blackout if you have supraventricular tachycardia (SVT). The main symptom is an abnormally fast heartbeat. Other symptoms include chest pain, tiredness, sweating, and palpitations. If you experience symptoms of SVT, we recommend booking an appointment with a cardiologist. Contact our clinic to arrange a consultation with Dr Ahsan, our Heart Rhythm Specialist.

SVT causes palpitations, feeling your heart racing very fast, dizziness, shortness of breath, and sometimes blackouts.

Video Description

Dr Syed Ahsan defines supraventricular tachycardia (SVT) as fast, regular heartbeats originating from the top of the heart. SVT is an umbrella term for a group of heart rhythm disorders, including paroxysmal supraventricular tachycardia (PSVT), atrial fibrillation (AF), atrial flutter and Wolff–Parkinson–White (WPW) syndrome. SVT can cause palpitations, dizziness, syncope (fainting) and other symptoms. Watch the rest of the videos in our SVT playlist to learn more about SVT.

SVT stands for supraventricular tachycardia. This is a fast, regular rhythm originating from the top chambers of your heart and can cause symptoms of palpitations, dizziness, or even fainting. SVTs can be treated very easily and with very good success rates.

Video Description

Dr Syed Ahsan lists the common supraventricular tachycardia (SVT) triggers: a stressful situation, tea, coffee or too much alcohol. Other triggers include a lack of sleep, taking specific medications for asthma, colds and allergies, and drug misuse. A change in posture can also trigger SVT. However, most people with SVT have no set trigger, making it hard to diagnose. Book an appointment with Dr Ahsan if you think you might have SVT.

Dr Syed Ahsan advises that if you have had several palpitation episodes that make you feel unwell or a single prolonged one, it is wise to book an appointment with your GP or a heart specialist. Dr Ahsan is our Heart Rhythm Specialist at London Heart Clinic and regularly performs ablation procedures to treat abnormal heart rhythms such as SVT. For high-quality, personalised care, book an appointment at our clinic.

Dr Syed Ahsan describes the three main types of SVT and their causes in our video. The first is atrial tachycardia, caused by a focus firing off at the top of your heart. The second is atrioventricular reciprocating tachycardia (AVRT), caused by extra wiring between the top and bottom of your heart. The third is atrioventricular nodal reentry tachycardia (AVNRT), caused by extra wiring within the pacemaker of your heart. Visit our page to learn more about supraventricular tachycardia.
