Wide 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 کامل[Post-infarction ventricular tachycardia with a QRS complex narrower than 140 ms: characterization and catheter ablation].
Typically, sustained monomorphic ventricular tachycardia (SMVT) in patients with a previous myocardial infarction (MI) is characterized by a wide QRS complex. However, occasionally patients present with SMVT and a narrow QRS complex (N-SMVT). We studied retrospectively the incidence of N-SMVT (i.e., QRS interval <140 ms) in patients with a previous MI and inducible SMVT who underwent electrophy...
متن کاملA Wide QRS Complex, Long RP Tachycardia:

متن کاملWide and narrow QRS complexes after arthroscopy.
A n obese (5 feet 5 inches, 224 pounds) 57-year-old woman with high blood pressure, diabetes mellitus, and arthritis underwent arthroscopy for a painful left knee. After the procedure, the electrocardiographic monitor in the recovery room showed alternately narrowing and widening QRS complexes, and a 12-lead electrocardiogram was obtained (Figure). e first three QRS complexes are wide (0.17 se...
متن کاملCatheter Ablation of Parahisian Premature Ventricular Complex
Catheter ablation is performed in selected patients with a symptomatic premature ventricular complex (PVC) or PVC-induced cardiomyopathy. Ablation of PVC from the His region has a high risk of inducing a complete atrioventricular block. Here we report successful catheter ablation of a parahisian PVC in a 63-year-old man.
