Reversed reciprocal rhythm.

Reversed reciprocal rhythm.

An example of reversed reciprocal rhythm is presented with associated 2:I heart block and other abnormalities of conduction. The electrocardiograms have been analysed and compared with an earlier electrocardiogram in which sinus rhythm was present. Despite dramatic electrocardiographic abnormalities, evidence is offered which suggests that there may have been only a small alteration in activity...

Escape-capture bigeminy. Mechanisms in S-A block, A-V block, and reversed reciprocal rhythm.

The term escape-capture bigeminy was coined by Bradley and Marriott (1958) in preference to "pseudo-reciprocal rhythm". This arrhythmia simulates reciprocal rhythm in having a P wave "sandwiched" between two QRS complexes. It differs from true reciprocal rhythm, however, in that the P wave is normal and does not result from retrograde activation. The purpose of this paper is to present three di...

Dissociation with interference, reciprocal rhythm, and coronary sinus rhythm.

Reversed diurnal blood pressure rhythm in hypertensive pregnancies.

1. Reversal of the normal diurnal blood pressure pattern has been demonstrated in women with severe hypertension and renal impairment in pregnancy (pre-eclampsia). 2. Maximum arterial pressure occurred at night in these women. The phenomenon was not due to hypotensive drug therapy or posture. Patients with uncomplicated essential hypertension in pregnancy retained a normal diurnal blood pressur...

Atrial reciprocal rhythm following DC conversion of atrial flutter.

T RADITIONALLY, reciprocal rhythms have been classified as atrial and ventricular on the basis of the site to which the impulse returns.1) While the ventricular reciprocal rhythm is not uncommon, the atrial rhythm is exceedingly rare, clinically.2) We experienced an example of atrial reciprocal rhythm following electrical conversion for atrial flutter. To our knowledge, no case of atrial recipr...
