Chamber enlargements on ECG

Chamber enlargements on ECG Atrial enlargement  The normal P wave has a maximum amplitude of 2.5 mm (0.25 mV) and a maximum width of 2.5 mm (100 ms). In right atrial enlargement, the amplitude increases while in left atrial enlargement, it is the width (duration) which increases. Both increases in biatrial enlargement. P wave abnormalities are best assessed in leads II and V1. Normal P wave is upright in lead II. In V1, a tiny initial spike is followed by a shallow negative wave. P mitrale: P mitrale is a notched and broad P wave with taller second peak indicating left atrial enlargement. It may be noted that initial part of P wave is contributed by right atrium as it is activated first and the second part by left atrium which is activated later. It is associated with a prominent negative deflection of P wave in V1, the left atrial component. P mitrale P pulmonale: Tall peaked P wave in right atrial enlargement is known as P pulmonale. It is found in cor pulmonale. The tall P of right atrial enlargement is called P congenitale. P wave axis is rightward in P pulmonale while it is leftward in P congenitale. The initial spike in V1 more than 1.5 mm in V1 is also a feature of right atrial enlargement. P tricuspidale has been described in tricuspid atresia. The pattern is mirror image of P mitrale. The initial peak is taller than the second peak in P tricuspidale. P pulmonale P tricuspidale   Ventricular enlargement While atrial enlargement is manifest as changes in P...

The long-term efficacy and safety of RDN require further investigation. For the first time, we report BP changes and safety up to 7 years after RDN, compared to drug adjustment in the randomised Oslo RDN study. MATERIALS AND METHODS: Patients with treatment-resistant hypertension, defined...

Authors: Zhang W, Xu JZ, Lu XH, Li H, Wang D, Wang JG Abstract PURPOSE: We hypothesise that dietary sodium intake interacts with serum uric acid to influence blood pressure (BP) in children and adolescents. In the present study, we investigated ambulatory BP in relation to hyperuricaemia, dietary sodium intake and their interaction in children and adolescents with hypertension. MATERIALS AND METHODS:  A total of 616 study participants were 10-24 years old and had primary hypertension diagnosed after admission in a specialised inpatient ward. Ambulatory BP monitoring was performed during hospitalisat...

Conclusions: The study ’s findings support the efficacy of tube weaning based on the published “Graz model of tube weaning” for children born with EA/TEF and indicate the necessity of specialized tube weaning programs for these patients.What is Known:• Children with esophageal atresia/tracheoesophageal fistula often suffer from feeding problems and tube dependency.• Different tube weaning programs and outcomes have been published, but not specifically for children with EA.What is New:• Evaluation of a large sample of children referred for tube weaning after EA repair.• Most children wi...

CONCLUSIONS: Neuro-ophthalmologic findings are mostly normal in patients with visual snow syndrome. Retinal or neurological diseases must be excluded as possible causes of visual snow. PMID: 33029971 [PubMed]

CONCLUSIONS: Young adult IS patients in Korea exhibit low awareness and poor management of their risk factors. Although the short-term outcome was relatively favorable in those patients, having SLE was associated with unfavorable outcomes. More attention needs to be paid for improving awareness and controlling risk factors in this population. PMID: 33029967 [PubMed]
