Bigeminal rhythm IV.
rhythm with each early complex having a wide QRS. Although the wide QRS superficially suggests that this is ventricular bigeminy, the perfect right-bundle-branchblock pattern (RS in lead I, qRS in lead V6, rsR ́ in lead V1) suggests that the early complex is an aberrantly conducted supraventricular complex. The atrial rhythm is typical counterclockwise atrial flutter with negative P waves in lea...
متن کاملVentricular tachycardia as default diagnosis in broad complex tachycardia.
In the differential diagnosis of broad-complex tachycardia, the most important decision is whether or not the tachycardia is ventricular, since this type carries the worst prognosis. However, the rules for a diagnosis of ventricular tachycardia are so complex that they are not satisfied in many cases, and the default diagnosis, supraventricular tachycardia, is erroneously accepted. We sought to...
متن کاملCorrelation of electrocardiogram parameters and hemodynamic outcomes in patients with isolated secundum atrial septal defects
OBJECTIVE The characteristic rSR' pattern in lead V1 on electrocardiogram (ECG) has been described in association with atrial septal defect (ASD) and right ventricular dilation. We aimed to determine if temporal ECG changes can guide a more discriminate and cost-effective screening during follow-up of isolated secundum ASD. METHODS Our study population included all pediatric patients followed...
متن کاملApproach to the difficult septal atrioventricular accessory pathway: the importance of regional anatomy.
Ablation of accessory tracts in the posteroseptal region can be challenging, as illustrated by these 2 cases. Familiarity of the anatomy of this region and recognition of the ECG patterns can help identify the AP origin and potentially improve success rates of ablation. The isoelectric initial preexcited QRS complex with rSR’ pattern in lead V1 of the surface ECG but not the relatively earlier ...
متن کاملPrecordial Lead Patterns in Right Ventricular Hypertension.
CURRENT criteria for the electrocardiographic diagnosis of right ventricular hypertrophy -3 depend primarily upon abnormal axis deviation and changes in the right precordial leads (V1, V4.R7). The R/S ratio in these leads has proved to be of great value in the recognition of right ventricular hypertrophy. Various patterns (qR, rS, rsR', Rs) are encountered and many theories have been put forwar...
