Active vs passive rhythms as an explanation of bigeminal rhythm with similar P waves.

چکیده
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.

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 کاملChanges of the brain’s bioelectrical activity in cognition, consciousness, and some mental disorders
Background: An electroencephalogram (EEG) is an accepted method in neurophysiology with a wide application. Different types of brain rhythms indicate that simultaneous activity of the brain cortex neurons depend on the person’s mental state. Method: we have focus on reviewing the existing literature pertaining to changes of the brain’s bioelectrical activity that recorded from the ...

The phenomenon of sleep is an active nervous and biologic rhythm, which is under influence of neurotransmitters of central nervous system. In this study, the influence of serotonergic system on sleeping time have been assessed by agonist-antagonist drugs using two methods of induction and non-induction behavioral and electrophysiology. The method used for measurement of total sleeing time was A...
