Bigeminal rhythm VII.
Figure 1. Electrocardiogram recorded 14 hours after admission. See text for explication. An earlier electrocardiogram recorded immediately after admission had a sinus rate of 92 beats/min and Wolff-Parkinson-White type preexcitation on all beats. A 57-year-old woman with a history of high blood pressure and dyslipidemia presented to the emergency department with chest pain, palpitations, dyspne...

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 کاملActive vs passive rhythms as an explanation of bigeminal rhythm with similar P waves.
We describe the criteria for differential diagnosis between 3:2 sinoatrial block from atrial bigeminy due to an ectopic focus in the sinus or parasinus zone. In the 3:2 sinoatrial block the RR interval of the basic rhythm is similar to the short R-R interval of the paired rhythm. In atrial bigeminy, the R-R interval of the basic rhythm is similar to the long R-R interval of the paired rhythm.
متن کاملMatrix Kummer-Pearson VII Relation and Polynomial Pearson VII Configuration Density
Abstract. A case of the matrix Kummer relation of Herz (1955) based on the Pearson VII type matrix model is derived in this paper. As a con- sequence, the polynomial Pearson VII configuration density is obtained and this sets the corresponding exact inference as a solvable aspect in shape theory. An application in postcode recognition, including a nu- merical comparison between the exact poly...
متن کاملVii. Conclusion
The concurrency is classified into two types: structured concurrency and nonstructured concurrency. After showing that the nonstructured concurrency cannot be represented by the conventional notations in the Petri net language, a method to represent such concurrency by the language is proposed. The proposed method allows us to utilize the existing approaches for analyzing properties of a nonstr...
