57 Possible Causes for Absent P Waves, T Wave Inversion

  • Atrial Fibrillation

    Fine fibrillatory waves in V1. ST depression / T wave inversion in the lateral leads could represent ischaemia or digoxin effect .[] P waves if arrhythmia is not captured on ECG then Holter monitoring in the outpatient setting these patients are hemodynamically stable telemitry in the inpatient setting[] Coarse fibrillatory waves in V1. Example 5 AF with slow ventricular response Irregular heart rate with no evidence of organised atrial activity.[]

  • Ventricular Fibrillation

    Presenting electrocardiogram (ECG) showed an old left bundle branch block and T-wave inversions in lateral leads (QTc 494ms) with no significant electrolyte abnormalities.[] Answers Rhythm: Irregular Rate: Unable to determine P Wave: absent PR interval: absent QRS: absent Interpretation: Ventricular Fibrillation (Fine) Description The morphologic[] The most common electrocardiographic (ECG) abnormality in ARVC/D is T-wave inversion in leads V 1 -V 3 .[]

  • Left Bundle Branch Block

    The precordial leads in these patients will demonstrate alarmingly deep, symmetrical T-wave inversions.[] The presence of a mid-QRS notching in more than two consecutive leads was a good predictor for the presence of SF (P 0.01), and when combined with an absent R-wave in lead[] His ECG immediately after arrival showed deep T-wave inversion in the precordial leads during normal conduction.[]

  • Bradycardia

    T-wave inversion was the most frequent ECG abnormality (n 31 patients), followed by ST segment changes (nine patients with elevation and six with depression).[] In third-degree, or complete, SA block, the surface ECG is identical to that of sinus arrest, with absent P waves.[] The P waves are usually identical and each are might proceed or follow QRS complexes. They maybe absent if they occurred during the QRS complex.[]

  • Ventricular Tachycardia

    In ARVC, T wave inversions and epsilon waves in the right precordial leads and incomplete RBBB are often present.[] Answers Rhythm: Regular Rate: 150 P Wave: absent PR interval: n/a QRS: Wide and bizarre Interpretation: Ventricular Tachycardia[] Rhythm Regular Rate Fast (100-250 bpm) P Wave Absent PR Interval Not measurable QRS Wide ( 0.10 sec), bizarre appearance Notes[]

  • Dextrocardia

    A 12-lead ECG with leads reversed appropriately for dextrocardia, revealed well-controlled atrial fibrillation with widespread T wave inversion in the anterior chest leads[] , aka ‘global negativity’ (inverted P wave, negative QRS, inverted T wave) Absent R-wave progression in the chest leads (dominant S waves throughout) These changes can be[] ’ (inverted P wave, negative QRS , inverted T wave) * Absent R-wave progression in the chest leads (dominant S waves throughout) Diagram above shows left-sided ECG recorded[]

  • Corrected Transposition of the Great Vessels

    Electrocardiogram (ECG) showed heart rate 84 per minute, T wave inversion in V1, V2, and V3.[] Electrocardiographic features that should suggest corrected transposition are atrioventricular block (particularly 2:1 or complete heart block), abnormal P waves, absent or[] The electrocardiogram (ECG) at rest showed a normal sinus rhythm with precordial ST- segment depression (V2 to V4), T-wave inversion (V2 to V3) and signs of biventricular[]

  • Hyperkalemia

    […] is characterized by a hereditary anomaly in the sodium ion channel (mutation of the SCN5A gene) identified by a wide QRS associated with the ST-segment elevation and the Twave[] Example of bradycardia with absent or flattened p waves in hyperkalemia. Care of Dr. Smith’s ECG blog.[] […] and width flattening or inversion U wave increased prominence rate, rhythm AV block, VF premature beats; tachyarrhythmias, torsades de pointes where: The P and T waves show[]

  • Sinus Bradycardia

    T-wave inversion 2 mm in 2 adjacent leads should prompt evaluation for structural heart disease. 10.[] In third-degree, or complete, SA block, the surface ECG is identical to that of sinus arrest, with absent P waves.[] ECG typically shows absent P waves with escape rhythm: Junctional - narrow complexes at 45-60 bpm. Ventricular - wide complexes at 30-45 bpm. Usual causes: Ischaemia.[]

  • Lown-Ganong-Levine Syndrome

    Example 2 Another example of the Type A WPW pattern with dominant R wave in V1 and right precordial T-wave inversions simulating RVH.[] QRS and no delta wave AV nodal (junctional) rhythm Short PR with abnormal or entirely absent p wave (retrograde p wave) Other conditions in which you may see a shortened[] Since ventricular depolarisation is abnormal, ventricular repolarisation is also abnormal and ST-segment depression and/or T wave inversion may be seen.[]
