A heart that suddenly starts racing can be difficult to ignore. You may feel perfectly fine one moment and experience a rapid heartbeat the next. Sometimes, the episode ends within minutes. At other times, it lasts longer and leaves you feeling tired, dizzy or uncomfortable. These episodes may be linked to supraventricular tachycardia (SVT), a condition involving abnormal electrical activity in the heart. While medication can help manage symptoms, some patients need a more targeted approach. SVT ablation is one treatment option that aims to correct the electrical pathway responsible for the rapid rhythm. For patients in Dubai, Abu Dhabi and across the UAE, understanding the condition and available treatment options is a useful first step towards better heart rhythm management. What Happens Inside the Heart During SVT? Your heart has an electrical system that controls the timing of every heartbeat. Normally, electrical signals begin in the sinoatrial node, travel through the atri...
The human heart follows a natural electrical rhythm that keeps blood circulating throughout the body. However, sometimes extra heartbeats occur due to abnormal electrical signals originating in the lower chambers of the heart. These are known as Premature Ventricular Contractions (PVCs). While occasional PVCs may not require treatment, frequent episodes can cause uncomfortable symptoms and sometimes affect heart function. A PVC ablation procedure is an advanced cardiac treatment designed to target the areas responsible for these abnormal electrical signals. It offers an effective treatment option for patients experiencing frequent PVCs, particularly when medication is ineffective or unsuitable. What Are Premature Ventricular Contractions (PVCs)? Premature Ventricular Contractions are extra heartbeats that originate in the ventricles, the lower chambers of the heart. Instead of following the heart's normal electrical pathway, these beats occur earlier than expected. Some people m...
