191 Possible Causes for Prominent A-Wave, Right Axis Deviation

  • Lateral Wall Myocardial Infarction

    ) Prominent R wave Prominent, upright T wave Combination of horizontal ST-segment depression with upright T wave What is the correct placement of leads V7 – V9?[] If the QRS is negative in Lead I, the heart is pointing more to the right than normal; hence, Right Axis Deviation.[] R waves are observed in the right precordial leads.[]

  • Cor Pulmonale

    On electrocardiogram, there was right axis deviation, p-pulmonale, features of right ventricular hypertrophy along with presence of prominent Q waves in leads II, III and[] Right axis deviation and low voltage may be noted in patients with pulmonary emphysema.[] The most typical ECG findings in emphysema are: Rightward shift of the P wave axis with prominent P waves in the inferior leads and flattened or inverted P waves in leads[]

  • Acute Cor Pulmonale

    Clinical findings associated with pulmonary heart disease include jugular venous distension, prominent v-wave in the jugular venous pulsation, narrow S-2 split or no split[] Other ECG findings in PE include right bundle-branch block, right axis deviation, atrial fibrillation, and T-wave changes ( 2, 3 ).[] The most typical ECG findings in emphysema are: Rightward shift of the P wave axis with prominent P waves in the inferior leads and flattened or inverted P waves in leads[]

  • 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[] In primum defects left axis deviation is seen in most patients with an axis of -30 degrees and very few patients have right axis deviation.[] The notched R waves in inferior leads are not so prominent. ECG 11.[]

  • Pulmonary Hypertension

    […] for conditions that can produce pulmonary hypertension (murmurs, collagen disease, valve pathology, VTE, OSA, alcohol consumption, chronic respiratory disease) Examination prominent[] Surface electrocardiogram showed right atrial and ventricular overload with right axis deviation.[] A prominent A wave may be observed in the jugular venous pulse. A right-sided fourth heart sound (S 4 ) with a left parasternal heave may be auscultated.[]

  • Biventricular Hypertrophy

    ST elevation in the right precordial leads V1-3 (“discordant” to the deep S waves). Prominent U waves (proportional to increased QRS amplitude).[] In the presence of LVH – Additional signs indicating RVH : Right atrial enlargement. Right axis deviation. Tall biphasic QRS complexes in multiple leads.[] The S waves are prominent in leads V5 and V6. The amplitude of R wave is more than 5 mm in lead VI.[]

  • Patent Ductus Arteriosus

    What is it? Patent ductus arteriosus (pronounced pay-tent duck-tus are-teer-e-o-sus) happens when a blood vessel fails to close after a baby is born. The ductus arteriosus is the temporary blood vessel that allows blood to bypass a baby's lungs before it is born. It is a blood vessel that joins the pulmonary[…][]

  • Right Ventricular Hypertrophy

    Q waves simulating an IMI appear in leads 2,3, and aVF.[] Example 4 Right ventricular hypertrophy in a patient with arrhythmogenic right ventricular cardiomyopathy (ARVC): Right axis deviation.[] […] in lateral (I, aVL, V5-6) leads tall, prominent R waves in lead V1 may be masked in the presence of COPD Radiographic features Plain radiograph Frontal view demonstrates:[]

  • Acute Massive Pulmonary Embolism

    The ECG may show: sinus tachycardia: the most common abnormality right heart strain pattern incomplete or complete right bundle branch block prominent R wave in lead V1 right[] His electrocardiogram showed wide-complex atrial fibrillation with rapid ventricular rate of 182, right axis deviation, right ventricular hypertrophy and inferior Q waves[] […] heart strain), - right axis deviation - s wave (I and aVL) 1.5mm - Q wave in III and aVF - p pulmonale - RBBB CXR: rules out other pathology, focal oligaemia, wedge density[]

  • Recurrent Pulmonary Embolism

    On physical examination, findings of right ventricular dysfunction include bulging neck veins with prominent v waves, a left parasternal lift, an accentuated pulmonic component[] Focal oligemia, cardiomegaly and plump pulmonary arteries on chest X-ray films, right axis deviation, clockwise rotation, ST-segment depression and T-wave inversion on electrocardiograms[] Review of EKGs showed a trend of increasing right axis deviation with recovery and recurrences during the previous 9 years and a current incomplete right bundle branch block[]
