A Particular Bigeminy During Atrial Tachycardia
The ECG shows clearly visible P waves only in lead V1 (Fig. 1). Regular PP intervals and an isoelectric baseline are present between the P waves, so the diagnosis is atrial tachycardia [1]. During the ECG recording, lead V1 shows 12 P waves but some of these are not visible because they are concealed by the QRS complex (Fig. 2). In lead V1, the beats following the long RR intervals are conducte...
متن کاملAlternating bundle branch block during atrial bigeminy.
Alternate patterns of ventricular excitation may occur with any type of supraventricular bigeminy. It is a physiologic phenomenon that depends on the rate dependency of bundle-branch refractoriness and the linking phenomenon related to concealed retrograde penetration of aberrantly conducted beats into their own blocked bundle branch [1–3]. An alternate pattern of ventricular activation can onl...
متن کاملA case of atrial bigeminy.
The electrocardiogram (Fig 1) reflects a basic sinus rhythm. Each sinus beat is associated with a blocked atrial extrasystole. This is evidenced by the premature and bizarre P' wave which is superimposed upon, and deforms, the S-T segment, and which is not followed by a QRS complex. The coupling interval of each extrasystole, the P-P' interval, is very short and measures 0.32 sec. The P'-P inte...
متن کاملAlternate patterns of premature ventricular excitation during induced atrial bigeminy.
SUMMARY Alternate patterns of premature ventricular excitation have been observed during induced atrial bigeminy in 18 subjects, including five normal volunteers. Each study was performed in the cardiac catheterization suite where a transvenous catheter electrode was positioned in the right atrium. Coupled or paired stimuli were delivered to the atrium by an isolated battery-powered source at a...
متن کاملComparison of atrial-His intervals during tachycardia and atrial pacing in patients with long RP tachycardia.
INTRODUCTION The purpose of this study is to describe a simple and reliable diagnostic maneuver that allows for the rapid differentiation of atypical AV nodal reentrant tachycardia (AVNRT) from other causes of long RP tachycardia. Long RP tachycardias may be caused by atypical AVNRT, orthodromic reciprocating tachycardia (ORT) involving a slowly conducting retrograde accessory pathway, or atria...
