If an ECG is not possible, a careful physical examination can yield helpful findings. For example, the presence of regular cannon A waves in the jugular venous pulse would be consistent with a 1 : 1 retrograde ventriculoatrial relation, as in tachycardias such as AVRT, AVNRT, ...
33-year-old male with no past medical history presented with palpitations and a baseline ECG notable for a marked 1st degree AV block (PR ≍ 400 ms). A subsequent ambulatory ECG monitor demonstrated intermittent high-degree AV block and recurrent non-sustained ventricular tachycardia (Fig. 1)...

Real-time assessment of LV synchrony in AV block population undergoing LBB pacing using ECG Imaging BACKGROUND. Left bundle branch pacing (LBBP) may prevent right ventricular (RV) pacing-induced dyssynchrony (DYS). Nowadays, real-time assessment of DYS co... M Martinez-Perez,M Pujol-Lopez,M...
A high-clinical suspicion for IE should be adopted especially when fever is present in patients with a prosthetic valve or device, new murmur or heart block, underlying valvular disease or congenital heart disease (CHD), embolism, immunosuppression, previous IE, or intravenous drug abuse (IVDA)....
Our findings could be used to assess the risks that current and next generation pesticides pose to honeybee populations. The pollination of various plants by bees is essential for biodiversity as well as for agriculture. The value of pollination services in the United States was estimated at US ...
No clinically meaningful changes from baseline over time were observed for any treatment group in Stage 1 or Stage 2 of the study for laboratory, vital signs, physical examination and ECG findings (ESM). 3.4 Immunogenicity The time of onset and frequencies of development of ADAs and nAbs were ...
The ECG showed 1掳 AV block (P-R interval 0.28 s). Treatment and course: Ceftriaxone was administered at once (4 g, followed by 2 g daily intravenously for 14 days). The P-R interval increased to maximally 0.31 s and transient incomplete right bundle branch block developed on the second...
An appraisal of initial QRS forces in left anterior fascicular block To assess whether it is appropriate to require small Q waves in Leads I and aV L for the diagnosis of left anterior fascicular block (LAFB), routine electr... LB Jacobson,L Lafollette,K Cohn - 《American Heart Journal...
This case reports on a middle-aged male patient with heart failure symptoms due to a 1st degree atrioventricular block with a marked PR prolongation of 480ms on electrocardiography (ECG). Because of heart failure symptoms as well as elevated N-terminal pro-B-type natriuretic peptide and no ...
