Ashman beats are described as wide complex QRS complexes that follow a short R-R interval preceded by a long R-R interval. [3] This short QRS complex typically has a right bundle branch block morphology and represents an aberrantly conducted complex that originates above the AV node, rather than a complex that originates in either the right or left ventricle.
Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14] Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [15]
Erythema (Ancient Greek: ἐρύθημα, from Greek erythros 'red') is redness of the skin or mucous membranes, caused by hyperemia (increased blood flow) in superficial capillaries. [1] It occurs with any skin injury, infection, or inflammation .
Fever, multiple painful joints, involuntary muscle movements, erythema marginatum [1] Complications: Rheumatic heart disease, heart failure, atrial fibrillation, infection of the valves [1] Usual onset: 2–4 weeks after a streptococcal throat infection, age 5–14 years [2] Causes: Autoimmune disease triggered by pathogenic strains of ...
Atrial fibrillation: Irregular impulses reaching AV node, only some being transmitted. The following types of supraventricular tachycardias are more precisely classified by their specific site of origin. While each belongs to the broad classification of SVT, the specific term/diagnosis is preferred when possible: Sinoatrial origin: [23]
Necrolytic acral erythema can show clinically as either acute or chronic. Flaccid blisters, erosions at the margins, and noticeable erythema are the symptoms of acute lesions. The hyperkeratotic surface, moderate erythema, and dark red border are seen in the chronic lesions. Edema may be present in conjunction. [4]
Right atrial enlargement (RAE) is clinically significant due to its prevalence in diagnosing supraventricular arrhythmias. Further, early diagnosis using risk factors like RAE may decrease mortality because patients with RAE are at 9x more risk of arrhythmias and other cardiac conditions compared to their healthy counterparts. [ 2 ]
Findings of tenderness, induration, pain, or erythema (redness) along the course of a superficial vein usually establish a clinical diagnosis, especially in patients with known risk factors. In addition, there is often a palpable, sometimes nodular "cord", due to thrombus ( blood clot ) within the affected vein.
