144 Possible Causes for Premature Atrial Contractions, Right Bundle Branch Block

  • Chronic Obstructive Pulmonary Disease

    […] deviation 110 without right bundle branch block; or some combination of these.[] Findings of right ventricular hypertrophy include an R or R ′ wave as tall as or taller than the S wave in lead V 1 ; an R wave smaller than the S wave in lead V 6 ; right-axis[]

  • Cor Pulmonale

    […] axis of the QRS, transient S-T depression of leads II, III, and aVF, and transient right bundle branch block. 6.[] […] axis deviation due to right ventricular hypertrophy Incomplete or complete right bundle branch block In some cases, P pulmonale S1Q3 pattern in acute cor pulmonale Chest[] Electrocardiographic findings in 67,375 asymptomatic subjects, VI: right bundle branch block. Am J Cardiol . 1960 ; 6 :143–152.[]

  • Multifocal Atrial Tachycardia

    Abstract Multifocal atrial tachycardia; right bundle branch block.[] In several patients there seemed to be a transition from multifocal premature atrial contractions through chaotic atrial tachycardia to atrial fibrillation.[] The only differences between these two groups were incidence of cor pulmonale, and right axis deviation, right bundle branch block, pulmonale P in electrocardiogram.[]

  • Premature Ventricular Contraction

    branch block (LBBB), right bundle branch block (RBBB), atrial premature contraction (APC), and paced beat (PB) rhythms.[] About PACs Premature atrial contractions (PACs) are premature heartbeats that are similar to PVCs, but occur in the upper chambers of the heart, an area known as the atria[] When describing PVCs or the morphology of nonsustained ventricular tachycardia, the terms “left bundle-branch block pattern” and “right bundle-branch block pattern” refer[]

  • Ventricular Bigeminy

    Ventricular Bigeminy with Right Bundle Branch Block Figure 4: Record 207 [3][4] Premature Ventricular Complex Bigeminy [Online image]. (2013).[] In atrial bigeminy, the other "twin" is a premature atrial contraction (PAC). After any PVC there is a pause that can lead to the development of bigeminy.[] The QRS of the sinus beat depicts IRBBB LAFB with a duration of 110 ms, and the QRS of the conducted PAC depicts complete right bundle branch block (CRBBB) LAFB.[]

  • Acute Cor Pulmonale

    ECG demonstrated new right bundle branch block (RBBB) with classical S1Q3T3 repolarisation abnormality of acute right heart strain (figure 1A).[] Other ECG findings in PE include right bundle-branch block, right axis deviation, atrial fibrillation, and T-wave changes ( 2, 3 ).[] Related Topics Right axis deviation Low voltage QRS complexes Right atrial enlargement (P pulmonale) Right ventricular hypertrophy Right bundle branch block References Harrigan[]

  • Supraventricular Tachycardia with Aberrant Conduction

    This can be either a left or right bundle branch block pattern. The following criteria suggest a supraventricular rhythm with aberrancy rather than VT: 1.[] Next chapter Premature Atrial Contractions (Atrial Beats / Extrasystoles) Related chapters Mechanisms of Cardiac Arrhythmias Premature Ventricular Contraction (Ventricular[] This could be due to rate variation, a concealed sinus block, or a premature atrial contraction (PAC).[]

  • Conduction Disorder of the Heart

    Bundle Branch Block Left bundle branch block and right bundle branch block of recent onset, indicate the need for a cardiovascular assessment by a specialist to rule out heart[] At least 3 distinct P-wave morphologies The PR Interval varies Ventricular rhythm is irregular Premature Beats Premature atrial contractions (PAC), Premature junctional complexes[] Abbreviations: AV : atrioventricular AVR : accelerated ventricular rhythm ECG : electrocardiogram PAC : premature atrial contraction PVC : premature ventricular contraction[]
