Atrial flutter and supraventricular tachycardia (SVT) are two common types of arrhythmias, or abnormal heart rhythms. They both cause the heart to beat faster than normal. However, there are some key differences between them.
Symptoms
Atrial flutter is usually characterised by a rapid, regular heartbeat. It can cause dizziness, chest pain, shortness of breath, and fatigue. SVT, on the other hand, tends to cause a very rapid, irregular heartbeat. Other symptoms may include palpitations, lightheadedness, and chest pain.
Causes
Atrial flutter is usually caused by a disruption in the electrical signals that control the heart's rhythm. SVT is often caused by an overactive thyroid gland or an imbalance of certain hormones, such as adrenaline.
Diagnosis
Both atrial flutter and SVT can be diagnosed using an electrocardiogram (ECG) or an echocardiogram (echo). An ECG is used to measure the electrical activity of the heart. An echo is used to create a picture of the heart and its chambers.
Treatment
Atrial flutter is usually treated with medications, such as beta-blockers or calcium channel blockers, to slow the heart rate. In some cases, ablation may be used to destroy the abnormal electrical pathways. SVT can be treated with medications, such as beta-blockers or calcium channel blockers, to slow the heart rate. In some cases, ablation may be used to destroy the abnormal electrical pathways. In severe cases, a pacemaker may be necessary to keep the heart rate controlled.
Conclusion
Atrial flutter and SVT are two common types of arrhythmias. While both can cause the heart to beat faster than normal, there are some key differences between them. Atrial flutter is usually characterised by a rapid, regular heartbeat, while SVT tends to cause a very rapid, irregular heartbeat. Treatment for both conditions typically includes medications and, in some cases, ablation or a pacemaker.
