Organik Kalp Hastalığı Olmayan Bir Vakada (İntra-atrial EKG ile Tanımlanmış) Ventriküler Taşikardi
Abstract
Ventricular tachycardia (VT) is a rare but serious arrhythmia often associated with structural heart disease. We report an 18-year-old man with four days of palpitations and cough, no prior heart disease, who presented in sustained VT at 214 bpm. Vagal maneuvers failed to slow the rhythm. Esophageal ECG demonstrated independent atrial (P) waves at 128 bpm, dissociated from the ventricular rate. Intra-atrial ECG via a transvenous electrode catheter definitively confirmed VT. Procainamide terminated the arrhythmia the same evening. Extensive evaluation—including right and left heart catheterization—showed no organic cardiac pathology. This case highlights the diagnostic challenge of distinguishing VT from supraventricular tachycardia with aberrancy and underscores the value of intra-atrial ECG for definitive rhythm identification.
