Tachycardia
  • Topics include concealed conduction, right and left atrial macroreentrant tachycardias, focal atrial fachycardias, AV nodal and AV reentrant tachycardia, wide complex tachycardias, ventricular tachycardia in CAD, ECG characteristics of outflow tract VT[books.google.com]
  • Abstract A description is given of a patient with an atrioventricular nodal tachycardia with left aberrant conduction changing into nonaberrant conduction after a ventricular premature beat.[link.springer.com]

  • Treating supraventricular tachycardia with aberrancy as though it were ventricular tachycardia is not dangerous; however, treating ventricular tachycardia as though it were supraventricular tachycardia with aberrancy can make a bad situation worse. 1,3[patientcareonline.com]

    • The cardinal features of fascicular VT are a right bundle branch block pattern with left axis deviation and a QRS duration of 0.11 0.14 seconds.[rcemlearning.co.uk]
    • There is also extreme left axis deviation with small r-waves in inferior leads followed by a large S-wave, and a small q-wave in aVL with a large R-wave; this is a left anterior fascicular block (LAFB) morphology.[epmonthly.com]
    • On the other hand, SVT with aberrant conduction will exhibit a mix of upright and inverted complexes throughout the precordial leads (Figure 3).6 Electrical axis SVTs with aberrancy will produce either a right or left axis deviation.[emsworld.com]

  • QRS Wave
    Wide QRS Complex
    • If the impulse is too premature , it may find one of the bundle branches still refractory from the previous impulse and will be conducted with a wide QRS complex . these premature atrial impulses that are followed by wide QRS complexes are aberrantly[afghanheart.wordpress.com]
    • This results in bundle branch block and hence " wide QRS complex ". Clinical significance Identification of the wide QRS complex as aberration helps to exclude the diagnosis of VPS . ECG 1a.[metealpaslan.com]
    • Several criteria have been described for differentiation between VT and SVT in the presence of a wide QRS complex. We report a case of wide QRS complex tachycardia with left BBB (LBBB) morphology and a retrograde P wave on the surface ECG.[e-arrhythmia.org]
