Electrocardiographic artifact mimicking ventricular tachycardia during high-frequency oscillatory ventilation: a case report.
Artifacts on electrocardiograms (ECGs) can simulate serious arrhythmias and thus lead to unnecessary diagnostic or therapeutic interventions. One cause of ECG artifacts is simultaneous use of other equipment while the ECG is being monitored or recorded. ECG artifacts mimicking either atrial or ventricular arrhythmia have been reported with the use of a variety of equipment (see Table). Muscle c...
متن کاملElectrocardiographical case. Narrow complex tachycardia provoked by the Valsalva manoeuvre.
A 19-year-old Chinese man presented with tachyarrhythmia during a human centrifuge session while performing a Valsalva manoeuvre at near normal (+1.4 Gz) centripetal forces. It was likely that the hydrostatic effects of sustained centrifugal forces, the distortion of the heart's shape, as well as swings in the autonomic dominance pre- and post-Valsalva manoeuvre, contributed to the tachyarrhyth...
متن کاملA Narrow QRS Complex Tachycardia:
An 80-year-old man underwent an electrophysiologic procedure because of recurrent episodes of supraventricular tachycardia. Episodes of nonsustained narrow QRS complex tachycardia occurred spontaneously after catheter placement. Examples of the onset and termination of an episode of tachycardia are shown in Figures 1 and 2, respectively. What is the mechanism of the tachycardia? What is the lev...
متن کاملTremor-induced ECG artifact mimicking ventricular tachycardia.
Ventricular Tachycardia To the Editor: The ECG from the article by Srikureja et al1 that adorns the cover of the September 12, 2000, issue of Circulation is a striking example of a tremor-induced artifact mimicking a serious arrhythmia. On this occasion, the apparent arrhythmia was ventricular tachycardia and led to the patient’s admission to the coronary care unit, although, in my experience, ...
متن کاملNarrow Complex Ventricular Tachycardia
Myocardial infarctions are frequently complicated by tachyarrhythmias, which commonly have wide QRS complexes (QRS duration > 120 milliseconds). Many published criteria exist to help differentiate between ventricular and supraventricular mechanisms. We present a case of a 61-year-old male with a history of hypertension, hyperlipidemia and coronary artery disease with prior stenting of the right...
