104 Possible Causes for Prominent A-Wave, Third Degree Atrioventricular Block

  • Atrial Septal Defect

    In sinus venosus ASD, it shows left axis deviation and a negative P wave in lead III.[] A new third degree atrioventricular block occurred in 1 patient who recovered 1 week later.[] Imaging The chest X-ray shows a dilated pulmonary artery, prominent pulmonary vascular markings, and enlarged right atrial and ventricular chambers in patients with significant[]

  • Electrolyte Imbalance

    We report a case of hyperkalemia, with concurrent hypocalcemia and hypomagnesemia resulting in (1) peaking of the T wave, (2) a prominent U wave, and (3) prolongation of the[] Occasionally sinoatrial (SA) block, second- or third-degree atrioventricular (AV) block may develop.[] Widened T wave B. Prominent U wave C. Prolonged QT interval D. Shortened ST segment 68. A. Prominent U waves B. Prolonged PR interval C. Depressed ST segment D.[]

  • Ostium Primum Atrial Septal Defect

    If MR is present, the findings of ASD may be modified Prominent v wave in JVP LV type apex IE may occur (unlike secundum ASD) ECG Incomplete RBBB pattern in v1 as in secundum[] The notched R waves in inferior leads are not so prominent. ECG 11.[]

  • Acute Myocardial Infarction

    Right heart catheterization will show prominent “V waves” in the pulmonary capillary wedge pressure tracing.[] There are hyperacute T waves, most prominent in V1-3. Q waves are forming in V1-3, as well as leads III and aVF.[] It appears as mild ST segment elevation that can be diffuse but more prominent in the precordial leads.[]

  • Third Degree Atrioventricular Block

    […] to the ventricles complete AV block complete atrioventricular block third degree AV block AV block third degree Atrioventricular Block, Third Degree Third Degree Atrioventricular[] Children with congenital third degree atrioventricular block may be symptomatic from birth.[] English third-degree atrioventricular block medical condition in which the impulse generated in the sinoatrial node (SA node) in the atrium of the heart does not propagate[]

  • Patent Foramen Ovale

    Brain abscesses are frequently caused by poly-microbial conditions. Comparatively, brain abscesses caused by Prevotella species are very rare. Right-to-left cardiac shunting due to a patent foramen ovale may predispose patients to infection. We report an isolated Prevotella brain abscess that occurred in a[…][]

  • Corrected Transposition of the Great Vessels

    ECG absence of Q waves in the lateral precordium (V4-6) physiologic Q waves in these leads often referred to as "septal" Q waves prominent Q waves in right precordium (V1-[] Since the patient had presented periods of third-degree atrioventricular block and was highly pacing-dependent during follow-up ICD consultations prior to hospitalization,[] degree atrioventricular (AV) conduction block 9 In this anomaly, the right atrium communicates with the morphologic left ventricle, which gives rise to the pulmonary artery[]

  • Restrictive Cardiomyopathy

    Examination: JVP 14 cm, prominent V waves and exaggerated Y descent. Hepatosplenomegally, peripheral oedema.[] His ECG showed prominent P-waves in all leads consistent with bi-atrial enlargement. His mother (III-17) had symptoms of heart failure from the age of 29 years.[] LV, left ventricle; RV, right ventricle; RA, right atrium. ( b ) 12-lead ECG in sinus rhythm with prominent P-waves in all leads, T-wave inversions, and incomplete right bundle[]

  • Diffuse Intraventricular Block

    Prominent R-wave in lead V1 (R/S ratio 1) WPW Posterior MI RBBB (or incomplete RBBB) Ventricular ectopy RVH Acute right ventricular dilatation (right ventricular “strain,”[] Complete bilateral bundle branch block results in complete (third degree) atrioventricular block. bundle branch block, complete heart block characterized by absence of conduction[] A 15-year-old patient with second-degree atrioventricular block and intermittent third-degree atrioventricular block (not shown) during invasive electrophysiologic study ([]

  • Tricyclic Antidepressant Overdose

    […] and T-wave inversion in V2–V3, and a prominent R wave in aVR.[] […] elevation and T-wave inversion in V2–V3, and a prominent R wave in aVR.[] An electrocardiogram (ECG) ( Figure 1 ) showed junctional complexes with retrograde P waves, complete right bundle branch block, prolonged QT interval, unusual ST segment[]
