Irregular wide QRS complex tachycardia in a patient with pulmonary hypertension: What is the mechanism?
Introduction Pulmonary hypertension (PH) results in right ventricular (RV) hypertrophy and dilation that could lead to the development of arrhythmogenic substrates for cardiac arrhythmias, which are important predictors and contributors to morbidity and mortality in these patients. To date, the mechanism of ventricular arrhythmia in patients with PH are less well understood. Here, we reported a...
متن کاملAdenosine-Responsive wide QRS complex tachycardia: what is the mechanism?
A 45-year-old man presented with an acute anterior wall myocardial infarction and underwent successful percutaneous transluminal angioplasty of the left anterior descending coronary artery. Twenty-four hours later, a wide QRS tachycardia at a rate of 108 beats/min that had a QRS duration of 150 msec was noted by telemetric monitoring. There were no symptoms associated with the tachycardia. A 12...
متن کاملWide QRS tachycardia. What is the mechanism?
A 70-year-old gentleman was referred for radiofrequency catheter ablation of wide QRS tachycardia that was not terminated with intravenous adenosine. Twelve-lead ECG was normal during sinus rhythm and transthoracic echocardiography demonstrated no evidence of structural heart disease. The electrophysiological study showed a normal AH interval of 104 m and HV interval of 45 m during sinus rhythm...
متن کاملWide QRS Complex Tachycardia
A 71-year-old man with a history of previous myocardial infarction was referred to our hospital for recurrent symptoms of palpitation and syncope. During an episode of palpitations, a 12-lead ECG (Figure 1) was obtained in the emergency room. The ECG shows a wide-QRS complex tachycardia at a rate of 167 bpm. The P waves are positive in lead II (↑) before each QRS complex, and the PR interval is...
متن کاملA regular, wide-QRS complex tachycardia: what is the tachycardia mechanism?
A 45-year-old woman underwent an electrophysiology procedure because of a 20-year history of recunent episodes of paroxysmal tachycardia. The baseline sinus cycle length, atrial-His. and His-ventricular intervals were 700, 60, and 45 msec, respectively, and the QRS duration was 80 msec. Ventricular pacing at a cycle length of 300 msec induced a tachycardia that had a cycle length of 320 msec an...
