112 Possible Causes for Incomplete Right Bundle Branch Block, Sinus Bradycardia

  • Secondary Cardiomyopathy

    Telemetry monitoring showed sinus bradycardia at 38bpm. The patient started complaining of shortness of breath.[] A previous ECG (two years ago) showed incomplete right bundle branch block morphology but no other abnormality.[] Discussion The admission ECG shows sinus tachycardia at a rate of 148bpm, incomplete right bundle branch block, ST-segment depressions in the inferior and anterolateral leads[]

  • Conduction Disorder of the Heart

    DISORDER OF IMPULSE FORMATION • SINUS BRADYCARDIA • VENTRICULAR RATE IS 9. SINUS BRADYCARDIA-ECG 10. SINUS-BRADYCARDIA 11.[] right bundle branch block.[] Sinus Bradycardia Sinus bradycardia is a sinus rhythm with a rate of 40-60 bpm Atrial fibrillation/flutter Irritable sites in the atria fire very rapidly, between 400-600[]

  • Athletic Heart Syndrome

    As mentioned previously, sinus bradycardia, AV blocks, extrasystoles, and early repolarization are hallmarks of athletic heart syndrome.[] Ventricular Hypertrophy criteria Wide QRS Complex (incomplete Right Bundle Branch Block ) Athletes: 14% Incidence Gene ral athletes: 10% Incidence Repolarization changes[] Of 21 marathon runners in the 1962 Commonwealth Games, 5 had incomplete right bundle branch block ( RBBB ) and 16 had increased QRS voltage suggesting left ventricular hypertrophy[]

  • Atrial Septal Defect

    Caused by hyperkalemia, extreme sinus bradycardia, digitalis toxicity and a congenital muscle disorder of dogs and cats. atrial systole see atrial contraction (above).[] The impact of incomplete right bundle branch block (IRBBB) and ASD diameter (  5 and  5 mm) on ASD diagnosis were also explored.[] bundle branch block pattern (rsR' in V1), and right axis deviation.[]

  • Cor Pulmonale

    HEART RATES• NORMAL HEART RATE• SINUS TACHYCARDIA 16. HEART RATES• SINUS BRADYCARDIA 17. COR PULMONALE 18.[] ECG shows the following changes: In acute pulmonary heart disease : right axial deviation, complete or incomplete right bundle branch block, sinus tachycardia, reversal of[] […] deviation and incomplete right bundle branch block Changes in cardiac conduction due to right-sided hypertrophy Echocardiography Normal heart size To show ventricular hypertrophy[]

  • Right Ventricular Hypertrophy

    Sinus bradycardia Sick sinus syndrome Heart block : Sinoatrial AV 1 2 3 Intraventricular Bundle branch block Right Left Left anterior fascicle Left posterior fascicle Bifascicular[] In contrast, when an incomplete right bundle branch block exists, the rSR' pattern is a relatively sensitive but nonspecific predictor of RVH.[] bundle branch block in the right precordial chest leads may signal the development of RVH In the limb leads right axis deviation develops and at times prominent Q waves simulating[]

  • Recurrent Pulmonary Embolism

    We describe two patients with transient sinus bradycardia and atrioventricular (AV) block during syncope from recurrent pulmonary embolism.[] 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[] EKG showed right axis deviation, a new incomplete right bundle branch block (IRBBB), clockwise rotation, and right heart strain with inverted T waves in V1–V4 ( Figure 2 )[]

  • Sick Sinus Syndrome

    Types of sick sinus syndrome Sinus bradycardia A normal heart rate is considered to be from 60 to 100 beats per minute.[] ECG examinations performed between 13 and 20 years old showed incomplete right bundle branch block and ST elevation with early depolarization.[] On postnatal electrocardiography, there was junctional escape rhythm due to profound sinus bradycardia, leading us to consider sick sinus syndrome.[]

  • Posterior Myocardial Infarction

    Sinus bradycardia. Note, leads V4, V5, and V6 still remain in positions V4R, V8, and V9 (respectively).[] right bundle branch block .[] This gentleman had an incomplete right bundle branch block (not labeled as ischemic heart disease) noted in his ECG (Figure 2) 10 years ago prior to hypophysectomy for pituitary[]

  • Angina Pectoris

    bradycardia, AV block Bradycardia, AV block, sick sinus syndrome Bronchoconstriction, muscle vasoconstriction, inhibited glycogenolysis Less vasodilatation in penis Provocation[] The electrocardiogram showed normal sinus rhythm, incomplete right bundle branch block with normal axis, and borderline left atrial abnormality.[] bradycardia, AV block AV block, sick sinus syndrome Fast effect dosage forms: Injection Table 4: Comparison between drugs within the group of nitrates Efficacy Safety Suitability[]
