Young Woman with Recurrent Palpitations Due to Arrhythmia
In the field of cardiology, arrhythmias can affect individuals of all ages. This case study highlights the journey of a 21-year-old female patient who experienced intermittent palpitations for a year before seeking medical attention. Her symptoms were initially brief and self-limiting, lasting only 1–2 minutes before resolving on their own. However, a recent episode was more intense and persistent, prompting her to seek hospital care.
Key Information
Patient: Female, 21 years oldDiagnosis: ArrhythmiaHospital: The Third Xiangya Hospital of Central South UniversityVisit Date: January 2022Treatment: Radiofrequency catheter ablation + aspirin therapyRecovery Time: 3-day hospitalization with long-term follow-upOutcome: Complete resolution of palpitations and stable health
Initial Consultation
The patient reported experiencing sudden, unexplained episodes of heart palpitations over the past year. These episodes were brief and resolved without intervention. However, a recent flare-up was more intense and did not subside, prompting her to seek medical help. Upon examination, her heart rate was 84 beats per minute, with a regular rhythm and no pathological murmurs. Echocardiography revealed normal cardiac structure and function. Based on these findings and her symptoms, she was diagnosed with arrhythmia and admitted for further treatment.
Medical Intervention
After admission, she underwent radiofrequency catheter ablation—a minimally invasive procedure to correct abnormal heart rhythms. During the operation, electrophysiological testing confirmed atrioventricular nodal reentrant tachycardia (AVNRT) caused by dual pathways in the atrioventricular node. Ablation was performed successfully, with post-procedure testing confirming the absence of inducible tachycardia. Following surgery, she was prescribed enteric-coated aspirin to prevent blood clots and support cardiovascular health.
Recovery and Results
The procedure was completed without complications. Post-operative vitals were stable, with a heart rate of 83 beats per minute and blood pressure of 118/76 mmHg. After a 3-day hospital stay, she reported no palpitations or related symptoms such as chest pain or shortness of breath. Physical examination revealed a heart rate of 82 beats per minute with a regular rhythm and no abnormal sounds. She was discharged with instructions to continue medication and maintain regular follow-ups.
Post-Discharge Guidance
As her condition improved, she was given detailed advice on post-treatment care. She was encouraged to rest adequately, avoid overexertion, and maintain a consistent sleep schedule. Moderate physical activity such as walking or light jogging was recommended, while high-intensity exercise was discouraged. Dietary recommendations included a low-salt, low-fat diet, and she was advised to avoid infections and manage stress. She was also instructed to monitor her heart rate and blood pressure regularly and to seek immediate medical attention if symptoms like blood in urine or stool appeared.
Clinical Insight
This case underscores the importance of early detection and treatment of arrhythmias, even in young and otherwise healthy individuals. While palpitations may seem minor, they can indicate underlying heart rhythm disorders that, if left untreated, may lead to serious complications such as heart failure or sudden cardiac arrest. Thanks to timely intervention and modern treatment options like radiofrequency ablation, this patient was able to recover fully and resume a normal lifestyle.
