Comparison of the Prevalence of First-Degree Atrioventricular Block in African-American and in Caucasian Patients: An Electrocardiographic Study III
|
Background: Electrocardiographic (ECG) differences occur between African-American and Caucasian patients.
Methods: The study includes ECGs of 2,123 patients, ages 20-99 years attending an urban hospital.
Results: First-degree atrioventricular (AV) block was more prevalent in African-American patients compared with Caucasian patients in all age groups of the study except for those patients in the eighth decade of life. The prevalence of first-degree AV block began to increase at ...

Neurocardiogenic syncope in chronic atrioventricular block
Journal of Electrocardiology
; Abstract We report a 37-year-old man with type I second-degree atrioventricular (AV) block (atypical Wenckebach's periodicity) referred to our department for pacemaker implantation because of an episode of syncope. After exhaustive evaluation, including electrophysiological test, in which

AV block. Which type and where?
Journal of Electrocardiology
; Abstract An electrocardiogram (ECG) showing sinus tachycardia with sinus rate exceeding the ventricular rate suggesting atrio-ventricular (AV) block in a patient with old anterior wall infarction is presented. The presence of varying PR intervals, irregular RR intervals and P-QRS relationship not

Wenckebach's periods or alternating Wenckebach's periods during 4:1 atrioventricular block?*
Journal of Electrocardiology
; Abstract This article deals with the tracings of a patient having episodes of atrial flutter with 4:1 atrioventricular (AV) block increasing to 8:1 AV block. This phenomenon was attributed to the coexistence of 3-level block due to transverse dissociation with 2:1 AV block in the most proximal

Second-Degree Atrioventricular Block: A Reappraisal
Mayo Clinic Proceedings
; Review In this review, we discuss the various forms and causes of second-degree atrioventricular (AV) block and the reasons they remain poorly understood. Both type I and type II block characterize block of a single sinus P wave. Type I block describes visible, differing, and generally decremental

Complete atrioventricular block in experimental murine myocarditis*
Journal of Electrocardiology
; Abstract Background: There were few reports on the pathological characteristics of the conduction system in myocarditis. This study was aimed to clarify the pathological characteristics of complete atrioventricular (AV) block in myocarditis. Methods and Results: We studied serial electrocardiograms

Transient complete atrioventricular block provoked by ventricular pacing in a patient with nonsustained ventricular tachycardia
Journal of Electrocardiology
; Abstract: A 75-year-old woman with complete left bundle branch block underwent electrophysiological study (EPS) to assess the conduction in the His-Purkinje conduction system and to further investigate the electrical instability in the ventricle, which was suggestive by the findings of nonsustained

Apparent bradycardia-dependent advanced second-degree atrioventricular block
Journal of Electrocardiology
; Abstract: A 65-year-old man with repeated chest discomfort and dizzy spells was transferred by an emergency car. On the way to hospital, his pulse was palpable as regular 4 to 5 beats followed by an unpalpable period of about 4 s. His electrocardiographic monitor showed that 4 to 5 sinus QRS
