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 consistent wit...
First-degree AV-block is a pure ECG diagnosis and is most commonly associated with a high vagal tone or drug toxicity. Second-degree AV-block includes two important subtypes, Mobitz type I (normally without clinical symptoms), and the potentially dangerous Mobitz type II, which is often ...
Prevalence of AV conduction disorders was 283 ± 465 events per month (epm) and was distributed in 14 ± 46 epm for third degree AV block, 195 ± 386 epm for second degree AV block, 73 ± 225 epm for first degree AV block and 0.2 ± 0.7 epm for pauses. During the study, sustained...
First, ECG during tachycardia shows a wide-complex rhythm in which the QRS does not resemble a typical left or right bundle branch block pattern and is identical to the maximally preexcited QRS during atrial pacing. Second, because ventricular activation occurs only over the AP and not through ...
Atrioventricular block indicates disturbance of conduction of the atrial impulse to the ventricles. In first-degree block the impulse is delayed. It is usually asymptomatic but may progress to second- or third-degree block. In second-degree block the impulse is blocked intermittently and in third-...
Case 2 was a 31-year-old woman with first-degree AV block and complete right bundle branch block with dyspnea on exertion and occasional syncope. She ... Yuzuki,Horie,Makita,... - 《Japanese Circulation Journal》 被引量: 10发表: 1997年 加载更多来源...
After the first follow-up, 81 % of the patients reported no symptoms. Paroxysmal atrial fibrillation/flutter combined with a high-degree AV-block seems no longer to be a contraindication for AV-synchronous pacing. 展开 关键词: cardiac DDD(R) pacemaker automatic mode switch paroxysmal ...

Five electrocardiogram (ECG) analyzing systems were tested with a microcomputer-based ECG signal generator to assess the accuracy of the systems in interpreting Wenckebach periodicity. Although normal sinus rhythm with normal PR intervals and sinus rhythms with first-degree atrioventricular (AV) block ...
