Ventricular tachycardia

A 70-year-old male patient develops a large anterior wall myocardial infarction. He is currently being managed with oxygen, aspirin, nitrates and a beta-blocker. He develops recurrent episodes of ventricular tachycardia and remains conscious however has dizzy spells and also becomes diaphoretic and hypotensive. An IV bolus of lidocaine is given followed by IV lidocaine infusion. • Which class of antiarrhythmics does lidocaine fall under? Lidocaine is a Class IB antiarrhythmic, fast sodium…

marked variations at the time of seizure and postictally. Tachycardia rates that reach a certain threshold may cause low cardiac output and possibly lead to cardiogenic shock. (91) Tachycardia…

for HCM, but the ECG abnormalities are not specific to HCM and should prompt further diagnostic evaluation. Left ventricular hypertrophy is nearly universal in symptomatic patients; however, individuals with localized hypertrophy may present with an entirely normal ECG. Typically, the ECG is deemed…

the heart rate. Body environment is also important with slow heart rhythm abnormalities.Hypothermia, or low body temperature, is a potential cause. 3. The symptoms of heart rythm disorders are Premature atrial contractions (PACs) and premature ventricular contractions (PVCs) are variations of normal and most often, people are unaware that an extra beat has occurred. However, some patients are keenly aware of any extra heartbeat, even if it is a normal variant and requires no treatment. That…

Peter had Dilated Cardiomyopathy (DCM) resultant episodes of Ventricular Fibrillation (VF) and Ventricular Tachycardia (VT). Cardiomyopathy describes a family of heart diseases affecting the heart muscle resulting in structural and functional abnormalities. (NICOL BOOK). In DCM a portion of the myocardium in the ventricles is dilated leading to progressive cardiac enlargement and hypertrophy. (cite cardiac book) Peter had a familial history which was compounded by alcohol misuse which further…

Introduction: Left ventricular non-compaction (LVNC) is a heterogeneous myocardial disease first described nine decades ago in 1926, by Grant et al (Medicine et al. 2014). At that time and still today, LVNC has been characterized by three primary criteria: prominent ventricular trabeculations, deep intertrabecular recesses, and the development of two distinct layers of myocardium, compacted and noncompacted (Chin et al. 1990). Similar to Grant et al’s original case, the majority of early…

special group of patients that have ventricular assist devices. The patient I had cared for that impacted me personally, was named Dorothy. Dorothy was one of the patients with a ventricular assist device. She was actually on of the individuals from the first group to receive a ventricular assist device at Duke University Hospital. Dorothy had a past medical history that involved the…

Acute pulmonary embolism (PE) is a common diagnosis throughout the world. In the US it affects approximately 1 in 1000 people and ranks as the 3rd most common cause of death in hospitalized patients. More than 80% of PEs are associated with DVTs in hospitalized patients with risk factors being recent trauma, surgery, immobility or obesity. While it can be entirely asymptomatic, nearly 25% of patients are thought to experience sudden death as their only manifestation of disease.1 Because of this…

senses dangerous fast rhythms. CRT-D can improve the pump 6,7function of the heart and reduce ventricular remodeling. The CRT works by providing electrical impulses that are sent to the left and right 6,7ventricle to improve the timing. Like the pacemaker and ICD the CRT-D generator is implanted in the chest or abdomen. The indications of the CRT and CRT-D are to treat dangerous ventricular arrhythmias, ventricular defibrillation, atrial tachyarrhythmia, heart muscle damage, AV blocks,…

associated with ventricular depolarization. • T wave – electrical associated with ventricular repolarization. • P-Q segment – associated atria plateau. (no electrical charge) • S-T segment – associated with ventricles plateau. (no electrical charge) • P-R interval – represent the period from atrial to ventricular depolarization. The time requires transmitting an action potential through the entire conduction system. • Q-T – interval – period from ventricular depolarization to ventricular…
