Essays on Antiarrhythmic

Monomorphic Ventricular Tachycardia

Cardiac arrhythmias often require immediate medical care that may include resuscitation (Ray, 2004). The diagnosis of cardiac arrhythmias can be challenging particularly in situations whereby the patient is asymptomatic and ECG findings are normal between symptomatic episodes (Cruickshank, 2008). Distinguishing between supraventricular and ventricular tachycardia is also a challenge (Australian Resuscitation Council, 2008). Cardiac arrhythmia should be suspected in patients with a history of syncope, near syncope, palpitations, and/or chest pain (Cruickshank, 2008). This paper will justify why monomophic ventricular tachycardia is the most likely diagnosis of a male patient who collapsed abruptly and has hypotension (BP 63/38), tachycardia ( ...

Cephalexin and Gentamicin The mechanism of action of amoxicillin is focused on the prevention of the synthesis of the bacteria’s cell wall through the binding and inhibiting of the cell wall transpeptidases (Katzung, Masters, and Trevor, 2012). Specifically, it attaches to the penicillin-binding protein 1A found in the cell wall of bacteria. Then, the agent disintegrates the lactam ring to allow the acylation of the penicillin-sensitive transpeptidase C-terminal domain. The formation of the cross-link of the linear peptidoglycan strands is prevented by the inactivation of transpeptidases. Since the third and last stage ...
