17 Possible Causes for Notched T-Wave on ECG

  • Long QT Syndrome 15

    エントリ H00720 名称 QT 延長症候群 下位グループ ロマノワード症候群 ジャーベル・ランゲ・ニールセン症候群 [DS: H02091 ] 概要 QT 延長症候群は心電図の QT 間隔の異常な延長と失神発作を示す心血管障害である。他の疾患や薬物の影響で起こる後天性と、心筋細胞のイオンチャネルをコードする遺伝子の異常による先天性がある。発作のないときは無症状であるが、発作時はトルサド・ド・ポアンツ (Tdp) と呼ばれる心室性不整脈を特徴とし、適切な医療処置を行わないと心室細動に移行して死亡することもある。QT[…][genome.jp]

  • 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]

  • Long QT Syndrome

    Long QT 2 : The ECG shows low amplitude T waves frequently with a notch.[healio.com] , the T wave is flattened or when notching of the T wave occurs.[doi.org] […] in LQTS2 can demonstrate low-amplitude and notched T-waves.[the-hospitalist.org]

  • Long QT Syndrome 14

    Long QT 2 : The ECG shows low amplitude T waves frequently with a notch.[healio.com] A , ECG traces from the initial patient described showing low-amplitude, notched T-waves characteristic of LQT2.[circ.ahajournals.org] A 12-lead ECG ( Figure 1A ) revealed a corrected QT interval of 550 ms with low-amplitude, notched T-waves. Figure 1.[circ.ahajournals.org]

  • Long QT Syndrome 6

    […] in LQTS2 can demonstrate low-amplitude and notched T-waves.[the-hospitalist.org] LQTS: Diagnostic Criteria ECG findings:  QTc, TdP, notched T waves, slow heart rate for age Clinical history: syncope, seizures, aborted cardiac arrest Family history: family[de.slideshare.net] […] abnormalities include notched, biphasic, or prolonged T-waves, and the presence of U-waves.4,5 Schwartz et al used these elements to publish criteria (see Table 1, right)[the-hospitalist.org]

  • Catecholaminergic Polymorphic Ventricular Tachycardia

    , the T wave is flattened or when notching of the T wave occurs.[doi.org] 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] […] patterns have been described previously. 22 , 23 LQT1 is associated with a broad-based T wave, LQT2 with a low-amplitude notched or biphasic T wave, and LQT3 with a long[dx.doi.org]

  • 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]

  • Brugada Syndrome

    , the T wave is flattened or when notching of the T wave occurs.[doi.org] QT measurement during adrenaline infusion can be challenging to interpret in the context of dynamic T-wave morphology changes, particularly when prominent U waves are present[doi.org] Assessing the ECG in all 12 leads may assist in defining the QT interval.[doi.org]

  • Ventricular Arrhythmia

    , the T wave is flattened or when notching of the T wave occurs.[doi.org] QT measurement during adrenaline infusion can be challenging to interpret in the context of dynamic T-wave morphology changes, particularly when prominent U waves are present[doi.org] Assessing the ECG in all 12 leads may assist in defining the QT interval.[doi.org]

  • 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]
