Man Successfully Treated for Supraventricular Tachycardia After Two Years of Symptoms
Supraventricular tachycardia (SVT) is a common type of heart rhythm disorder that, in severe cases, can significantly impact hemodynamic stability. This case highlights a 60-year-old male who had been experiencing episodes of palpitations, dizziness, and fatigue for over two years. After being admitted to the hospital with acute symptoms, he was diagnosed with paroxysmal supraventricular tachycardia. Following a comprehensive evaluation and electrophysiological study, he underwent a successful radiofrequency ablation procedure. His symptoms resolved completely, and he has remained free of episodes since treatment.

Initial Consultation
The patient arrived at the hospital experiencing sudden palpitations, dizziness, and excessive sweating. He was visibly anxious and described having difficulty monitoring his own pulse at home. An ECG confirmed supraventricular tachycardia. During our conversation, he revealed that he had experienced similar episodes more than two years earlier. These episodes were brief at first, lasting about 30 minutes, and would stop as suddenly as they began. He had dismissed them as harmless and had not sought medical attention. However, he noted that the episodes had become more frequent and more intense over time, prompting him to finally seek help.
Medical Intervention
Understanding the Condition
Paroxysmal SVT is known for its sudden onset and termination. While patients often feel completely normal between episodes, the unpredictable nature of the condition can cause significant distress. Given the increasing frequency and severity of the patient's symptoms, we recommended an electrophysiology study followed by catheter ablation for a potential cure.
Addressing Patient Concerns
The patient and his family were initially hesitant about undergoing a minimally invasive procedure and preferred medication management. We took time to explain the mechanism of SVT, the limitations of long-term drug therapy, and the high success rate of ablation. As their understanding improved, their concerns about the procedure diminished. They ultimately agreed to the procedure to eliminate the unpredictability of the condition.
Successful Procedure
An electrophysiology study confirmed the presence of dual atrioventricular nodal pathways. A targeted 30-second radiofrequency ablation successfully corrected the abnormality. Multiple attempts to induce tachycardia during the procedure failed, confirming the effectiveness of the treatment.
Post-Operative Recovery
The patient remained awake throughout the procedure and later remarked, "I didn't realize minimally invasive surgery was this simple. I wish I had done it sooner." Following the procedure, he experienced no further episodes of palpitations, dizziness, or sweating. His confidence and mood improved significantly, and he no longer felt restricted in his daily activities. His family also felt relieved, no longer fearing that he might experience an episode while out alone. He was discharged after four days of observation with no complications.
Post-Treatment Recommendations
While SVT is generally not life-threatening, the unpredictable nature of the episodes can cause significant anxiety. With a success rate of over 95%, catheter ablation offers a long-term solution without the need for ongoing medication or lifestyle restrictions.
Patients are encouraged to resume normal activities gradually after surgery. Adequate rest and sleep are important, as is avoiding excessive fatigue and stress. Engaging in enjoyable activities like music or relaxing entertainment can help maintain a positive mindset. If symptoms of palpitations recur, patients should seek prompt medical evaluation with an ECG or Holter monitor to determine the cause—often benign premature beats. Reassurance and follow-up are key components of long-term care.
Clinical Insights
Paroxysmal supraventricular tachycardia is one of the few cardiac rhythm disorders that can be definitively cured. Accurate diagnosis through ECG during an episode is essential. Electrophysiology-guided ablation offers a highly effective, minimally invasive treatment option. Beyond the physical benefits, successful treatment can dramatically improve a patient's psychological well-being by removing the fear and uncertainty associated with unpredictable episodes.
As healthcare providers, it is crucial to communicate clearly and compassionately about treatment options. Explaining the procedure, its benefits, and expected outcomes helps alleviate patient and family anxiety, ultimately leading to better health decisions and outcomes.
