Why the study?
Does Transcutaneous Electrical Nerve Stimulation (TENS) therapy induce syncope or arrhythmias in patients with Brugada syndrome?
Does Transcutaneous Electrical Nerve Stimulation (TENS) therapy induce syncope or arrhythmias in patients with Brugada syndrome?
TENS therapy may induce increased vagal tone leading to bradycardia, dynamic ECG changes, and syncope in patients with Brugada syndrome, representing a potential safety risk.
TENS may provoke syncope and ECG changes in Brugada syndrome; hypothesis-generating case report leaves open need for safety studies.
38 year old male patient with preauricular abcess developed presyncope during high-grade fever and diagnosed as having Brugada syndrome with type 1 ECG pattern. The diagnosis of Brugada syndrome was made in educational and research hospital. His Electroencephalography (EEG) was normal. Coronary angiography showed myocardial bridging of the left anteriyor descending coronary artery after second diagonal branch and no hemodynamically significant coronary artery disease. Technesium (TC99 MIBI) Myocardial Perfusion SPECT and Cardiac Magnetic Resonance imaging results were normal. Ajmaline test confirmed the diagnosis, and ventricular fibrillation (VF) induced during electrophysiological study (EPS). There was no family history of sudden death.
