16 Possible Causes for 1 atrioventricular block, Exertional Syncope, P Pulmonale

  • Recurrent Pulmonary Embolism

    The electrocardiogram on admission showed a regular sinus rhythm with a ventricular rate of 90 beats per minute, a QRS axis at 70o, a 1 st degree atrioventricular block (PR[] pulmonale - RBBB CXR: rules out other pathology, focal oligaemia, wedge density (pulmonary infarction) ABG: reduced PaO2 in keeping with size of PE, metabolic acidosis with[] Right axis deviation (R S in V1) and P-pulmonale may be present. T-wave inversion in leads V1 to V4 also occurs.[]

  • Ayerza Syndrome

    Complete atrioventricular block complicating acute myo- cardial infarction in the thrombolytic era. J Am Coll Cardiol 1999;34:1721–1728. 116.[] Incidence, predictors, and outcomes of high-degree atrioventricular block complication acute myocardial infarction treated with thrombolytic therapy.[] J Cardiovasc Electrophysiol 2006;17:1–5. 115. Harpaz D, Behar S, Gottlieb S et al., SPRINT Study Group, the Israeli Thrombolytic Survey Group.[]

  • Acute Cor Pulmonale

    Exertional syncope - a late symptom (indicating severe disease).[] The electrocardiogram on admission showed a regular sinus rhythm with a ventricular rate of 90 beats per minute, a QRS axis at 70o, a 1 st degree atrioventricular block (PR[] Peaked P waves in the inferior leads 2.5 mm (P pulmonale) with a rightward P-wave axis (inverted in aVL) Clockwise rotation of the heart with a delayed R/S transition point[]

  • Atrial Septal Defect

    Symptoms such as exertional dyspnoea, fatigue, palpitations and syncope can occur and increasing age carries an increasing risk of stroke.[] A new third degree atrioventricular block occurred in 1 patient who recovered 1 week later.[] RESULTS: Thirty-four patients were occluded successfully under this approach and 1 patient was transferred for surgical repair for dislodgement of the occluder.[]

  • Right Ventricular Hypertrophy

    Coronary artery disease: Myocardial ischemia is the most common cause of exertional chest pain, and it also can cause ischemia-induced arrhythmias with exertional syncope.[] We also excluded 107 participants (1.6%) with interventricular conduction delay, left bundle branch block, Wolff-Parkinson-White syndrome, advanced atrioventricular block,[] Supporting criteria Right atrial enlargement (P pulmonale).[]

  • First-Degree Atrioventricular Block

    syncope (particularly on exertion) Investigations ECG PR interval exceeds 200msec (1 big square) Management The risk is that these patients will develop 2nd degree heart[] ECG Examples: First-Degree Atrioventricular (AV) Block ECG (Example 1) First-Degree Atrioventricular (AV) Block ECG (Example 2) First-Degree Atrioventricular (AV) Block ECG[] RV hypertrophy can probably be ruled out in this case because there is no right axis deviation or P pulmonale.[]

  • Left Cardiac Ventricle Disorder

    Typical symptoms include exertional dyspnea and fatigue.[] The ventricular response is equal to or less than 2:1. Occasionally, atrioventricular block of high degree with ventricular bradycardia are seen.[] pulmonale.[]

  • Ventricular Bigeminy

    Syncope or near syncope (especially exertional syncope, which is a serious symptom [ 13 ] ).[] VPB has a right or left bundle branch block morphology. 1 Electrocardiogram Findings An ECG should be part of the standard evaluation for any patient with suspected VPBs.[] Peaked P waves suggest right atrial enlargement, cor pulmonale, but have a low predictive value, a P wave with increased amplitude can indicate hypokalemia.[]

  • Atrial Tachyarrhythmia with Short PR Interval

    Clinical symptoms of SVT May be asymptomatic Regular, episodic, or irregular palpitations Chest pain at rest or with exertion Dyspnea at rest or with exertion Weakness or[] […] with 2:1 Atrioventricular (AV) Block ECG (Example 2) Ectopic Atrial Bradycardia ECG References: 1.[] Characterized by a rapid heart rate with P waves difficult to distinguish D. Causes 1. Digoxin toxicity, most common cause 2.[]

  • Left Ventricular Hypertrophy

    Patients with anomalous origin of the left coronary artery from the pulmonary trunk may present with paroxysmal angina on exertion, congestive heart failure, dyspnoea, syncope[] […] st degree atrioventricular block (AVB) in five cases (17%).[] P-pulmonale)[]
