25 Possible Causes for Notched T-Wave on ECG

  • Long QT Syndrome 15
  • Sudden Cardiac Death

    Those with the genetic mutation most likely to develop SADS possess distinctive bumps, or notched T-waves, in their ECG readouts.[time.com] And if his sister has a more notched t-wave, then she is at more risk.”[newscientist.com] Better diagnosis “We show that the degree of t-wave notching is correlated with how much risk they are at,” says team member Arash Sadrieh.[newscientist.com]

  • Pericarditis

    Stage II: ST segment elevation and PR depression have resolved and T waves may be normal or flattened. Stage III: T waves are inverted, and the ECG is otherwise normal.[healio.com] Stage I (acute phase): Diffuse concave upward ST segment elevation in most leads, PR depression in most leads (may be subtle) and sometimes notching at the end of the QRS[healio.com]

  • Long QT Syndrome

    Long QT 2 : The ECG shows low amplitude T waves frequently with a notch.[healio.com] The QT interval should cover the second component of a notched T wave. The notched T wave in precordial leads V3 to V4 or in inferior leads is an ECG feature of LQT2.[thecardiologyadvisor.com] […] in LQTS2 can demonstrate low-amplitude and notched T-waves.[the-hospitalist.org]

  • Torsades De Pointes

    The QT interval should cover the second component of a notched T wave. The notched T wave in precordial leads V3 to V4 or in inferior leads is an ECG feature of LQT2.[thecardiologyadvisor.com] The 12-lead ECG was normal in terms of heart rhythm, without prolongation of QTc interval and without electrical instability (alternating T, notched T and U waves and ST-segment[elsevier.pt] There are genotype-specific T wave patterns on 12-lead ECG in the common forms of LQTS ( Figure 3 ). For LQT1, QTc prolongation is accompanied by broad-based T waves.[thecardiologyadvisor.com]

  • Early Repolarization Syndrome

    The R-wave descending branch has obvious notches or blurs, similar to the right bundle branch block diagram. 5. T wave is towering or inverted.[healthfrom.com] Examine Early repolarization syndrome examination Mainly by ECG diagnosis, ECG ERS features: 1.[healthfrom.com]

  • Acute Pericarditis

    Stage II: ST segment elevation and PR depression have resolved and T waves may be normal or flattened. Stage III: T waves are inverted, and the ECG is otherwise normal.[healio.com] Stage I (acute phase): Diffuse concave upward ST segment elevation in most leads, PR depression in most leads (may be subtle) and sometimes notching at the end of the QRS[healio.com]

  • Familial Short QT Syndrome

    Genotype-phenotype Correlation The ECG study showed a lower frequency of typical notched T waves, 13 with only 23% of carriers showing this pattern.[revespcardiol.org] The resulting ECGs exhibited striking similarities with the actual ECG of the proband showing wide and notched QRS morphology, as well as asymmetrical and tall T-wave merging[pnas.org] Electrocardiographic Study of Mutation Carriers The typical notched T waves on the ECG were observed in 3 (23%) patients ( Figure 3 ), with broad T waves being the predominant[revespcardiol.org]

  • Long QT Syndrome 14

    Long QT 2 : The ECG shows low amplitude T waves frequently with a notch.[healio.com] The T-wave in LQTS2 is usually low-amplitude and bifid, with notching 12,13 (Figure 2).[revespcardiol.org] Computer-generated ECG measurements and interpretation should be accompanied by operator review. 6 Table 3: Laboratory tests Notched or bifid T-waves may serve as a useful[nature.com]

  • Long QT Syndrome 8

Note the notched T waves particularly in lead II and the rhythm strip at the bottom of the ECG.[karger.com] Computer-generated ECG measurements and interpretation should be accompanied by operator review. 6 Table 3: Laboratory tests Notched or bifid T-waves may serve as a useful[nature.com] Electrocardiographically, a prolonged QT interval is seen with characteristic low amplitude and notched T waves often visualized best in the limb leads or rhythm strip (fig[karger.com]
