However, the ventricular response rate is temporarily slowed with adenosine in such cases.Because of the effects of adenosine on AV node-dependent SVTs, adenosine is considered a class V antiarrhythmic agent. When adenosine is used to cardiovert an abnormal rhythm, it is normal for the heart to enter ventricular asystole for a few seconds. This can be disconcerting to a normally conscious patient, and is associated with angina-like sensations in the chest. Nuclear stress test
Adenosine is used as an adjunct to thallium (TI 201) or technetium (Tc99m) myocardial perfusion scintigraphy (nuclear stress test) in patients unable to undergo adequate stress testing with exercise. Dosage
When given for the evaluation or treatment of a supraventricular tachycardia (SVT), the initial dose is 6 mg to 12 mg, depending on standing orders or provider preference, given as a rapid parenteral infusion. Due to adenosines extremely short half-life, the IV line is started as proximal (near) to the heart as possible, such as the antecubital fossa. The IV push is often followed with a flush of 10–20 mL of normal saline. If this has no effect (i.e., no evidence of transient AV block), a dose of 12 mg can be given 1–2 minutes after the first dose. When given to dilate the arteries, such as in a "stress test", the dosage is typically 0.14 mg/kg/min, administered for 4 or 6 minutes, depending on the protocol. The recommended dose may be increased in patients on theophylline since methylxanthines prevent binding of adenosine at receptor sites.
These people slowly stopped acting as subsistence farmers (who created goods in their own homes to trade with neighbors) and began to represent what we think of a "craftsman" today.In recent years, crafts and craftspeople have slowly been gaining momentum as a subject of academic study. For example, Stephanie Bunn was an artist before she became an anthropologist, and she went on to develop an academic interest in the process of craft - arguing that what happens to an object before it becomes a product is an area worthy of study. The Arts and Crafts Movement
The term crafts is often used to describe the family of artistic practices within the family of decorative arts that traditionally are defined by their relationship to functional or utilitarian products (such as sculptural forms in the vessel tradition) or by their use of such natural media as wood, clay, ceramics, glass, textiles, and metal. The Arts and Crafts Movement originated in Britain during the late 19th century and was characterized by a style of decoration reminiscent of medieval times. The primary artist associated with the movement is William Morris, whose work was reinforced with writings from John Ruskin. The movement placed a high importance on the quality of craftsmanship, while emphasizing the importance for the arts to contribute to economic reform. Studio crafts
Crafts practiced by independent artists working alone or in small groups are often referred to as studio craft. Studio craft includes studio pottery, metalwork, weaving, woodturning, paper and other forms of woodworking, glassblowing, and glass art.
