29 Possible Causes for Incomplete Right Bundle Branch Block, P Pulmonale, Pulmonary Systolic Murmur

  • Eisenmenger Syndrome

    ECG: almost always abnormal; shows features suggestive of right heart hypertrophy (with tall R wave in V1, deep S wave in V6, ST and T wave abnormalities, P pulmonale) as[patient.info] Along the left sternal border systolic murmur can be heard, and early pulmonary systolic shock.[remedyland.com] Ejection systolic murmur audible along the left sternal border.[patient.info]

  • Left to Right Cardiac Shunt

    Auscultatory findings Harsh h olosystolic murmur over the left lower sternal border ; typically louder in small defects Mid- diastolic murmur over cardiac apex Systolic thrill[amboss.com] (harsh, long crescendo-decrescendo systolic ejection murmur along the left sternal border).[cancertherapyadvisor.com] Systolic murmur with point of maximal intensity over the second left ICS, sternal border Diagnostics Echocardiography : confirmatory test ; assessment of severity of stenosis[amboss.com]

  • Cor Pulmonale

    In ECG, P pulmonale was observed in 58 (99.66%) of cases. 48 (80%) were having right ventricular dilatation and right atrial dilation was observed in 30 (50%) of patients.[scopemed.org] Split second heart sound with loud pulmonary component. Systolic ejection murmur with a sharp ejection click over the pulmonary artery (advanced sign).[patient.info] […] deviation and incomplete right bundle branch block Changes in cardiac conduction due to right-sided hypertrophy Echocardiography Normal heart size To show ventricular hypertrophy[nursing.unboundmedicine.com]

  • Atrial Septal Defect

    MurmursPulmonary ejection systolic murmur – Increased pulmonary flow • Tricuspid murmur – is heard over left sternal edge louder on inspiration • Graham-Steell murmur[slideshare.net] The impact of incomplete right bundle branch block (IRBBB) and ASD diameter (  5 and KEYWORDS: Crochetage on R wave; Inferior leads; Pediatric; Secundum atrial septal defect[ncbi.nlm.nih.gov] ECG incomplete right bundle branch block (RBBB morphology with QRS duration between 110-120 ms) increased specificity with crochetage sign in the inferior (II, III, aVF) leads[radiopaedia.org]

  • Pulmonary Embolism

    Electrocardiographic findings ACS ( n 198) APE ( n 81) TC ( n 21) p value P pulmonale (%) 8 (4) 10 (12) 0 0.014 Right axis deviation (%) 0 6 (7) 0 Left axis deviation (%)[ncbi.nlm.nih.gov] Signs of pulmonary hypertension, such as palpable impulse over the second left intercostal space, loud P 2, right ventricular S 3 gallop, and a systolic murmur louder on inspiration[emedicine.medscape.com] Among these, ECG changes including sinus tachycardia, new-onset atrial arrhythmias, new right bundle-branch block (complete or incomplete), Qr pattern in V1, S1Q3T3 pattern[circ.ahajournals.org]

  • Acute Cor Pulmonale

    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[lifeinthefastlane.com] Split second heart sound with loud pulmonary component. Systolic ejection murmur with a sharp ejection click over the pulmonary artery (advanced sign).[patient.info] […] or complete right bundle branch block (2) S waves in leads I and aVL of 1.5 mm (3) a shift in the transition zone in the precordial leads to V5 (4) Q waves in leads III and[ispub.com]

  • Pulmonary Hypertension

    […] failure – increased JVP, (large V waves), parasternal heave, TR murmur, hepatomegaly, peripherial oedema other signs of CHF hypoxaemia INVESTIGATIONS Bedside ECG – RVH, RAD, p-pulmonale[lifeinthefastlane.com] Clinical signs include right ventricular (parasternal) heave, a loud pulmonary second heart sound, murmur of pulmonary regurgitation, systolic murmur of tricuspid regurgitation[patient.info] Right axis deviation (short arrow), increased P-wave amplitude in lead II (black arrowhead), and incomplete right bundle branch block (white arrowhead) are highly specific[aafp.org]

  • Endocardial Cushion Defect

    A systolic murmur of a ventricular septal defect can be heard as well as the systolic murmur of mitral insufficiency.[chdbabies.com] […] hypertension; a grade 2 to 3/6 systolic murmur; and sometimes a diastolic murmur at the apex and low left sternal border (see table Heart Murmur Intensity ).[merckmanuals.com] If a significant regurgitation of the common atrioventricular valve is present, a systolic cardiac murmur and gallop rhythm are frequently heard.[doi.org]

  • Right Ventricular Hypertrophy

    Supporting criteria Right atrial enlargement (P pulmonale).[lifeinthefastlane.com] On auscultation, an accentuated second pulmonary sound (S2), a third heart sound termed a ‘right ventricular gallop’, as well as a systolic murmur over the tricuspid area[en.wikipedia.org] In contrast, when an incomplete right bundle branch block exists, the rSR' pattern is a relatively sensitive but nonspecific predictor of RVH.[ncbi.nlm.nih.gov]

  • Right Atrial Hypertrophy

    The P-wave amplitude is 2.5 mm in P pulmonale.[ecgwaves.com] In the absence of pulmonary hypertension, the murmur is usually low-intensity and early systolic.[patient.info] Incomplete right bundle branch block suggests slowing of electrical impulse conduction in the right bundle branch of the conduction system.[healthtap.com]
