Wide-complex tachycardia.
To the Editor: The Images in Cardiovascular Medicine section of the August 29, 2000 issue of Circulation presented a case of wide-complex tachycardia (WCT) that reportedly required placement of a transesophageal lead to diagnose ventricular tachycardia (VT).1 Pharmacological trials of adenosine, diltiazem, lidocaine, and procainamide were noted to be unhelpful. In our view, the diagnosis of VT ...
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 کاملAn Irregular Wide Complex Tachycardia.
A 66-year-old woman with a history of hypertension and persistent atrial fibrillation was referred to the Arrhythmia Clinic. Before her visit, a routine 12-lead ECG was ordered (Figure 1). The patient was asymptomatic except for minor palpitations. Her medicine regimen included apixaban, flecainide 150 mg twice daily, lisinopril, loratadine, metoprolol, and simvastatin. What is the cardiac rhyt...

predominance (M3+ to M4+), weakness for hip flexion bilaterally (M5–), and for foot extension and flexion bilaterally (M2 and M4–), hyperextensible joints, absent tendon reflexes, hypotonia, ataxia, and a positive Gower’s sign. Creatine kinase was 60 U/l (normal: ! 171 U/l). Hb A 1c was 6.4% (normal: 3.5–6.0%). Triglycerides and cholesterol were elevated. Ophthalmologic investigations revealed ...
متن کاملArtefact mimicking tachycardia during magnetic resonance imaging in a patient with an implantable loop recorder.
An implantable loop recorder (ILR) was implanted in a 45 year old man with recurrent syncope. A subsequent episode of injurious syncope led to performance of a cranial and shoulder magnetic resonance imaging (MRI). An artefact mimicking both wide and narrow complex tachycardias was recorded by the ILR during the shoulder MRI but not the cranial MRI. Caution should be used when interpreting the ...
