Ventricular fibrillation

(2) Accelerated idioventricular rhythm An accelerated idioventricular rhythm is seen in as many as 20% of patients who have an AMI. This pattern is defined as a ventricular rhythm characterized by a wide QRS complex with a regular escape rate faster than the atrial rate, but less than 100 bpm. AV dissociation is frequent. Slow, nonconducted P waves are seen; these are unrelated to the fast, wide QRS rhythm. Most episodes are short and terminate spontaneously. They occur with equal frequency in…

individuals being enrolled in this study, of which 583 individuals initially presented with ventricular fibrillation and 776 individuals initially presented with a cardia rhythm other than ventricular fibrillation. In patients with ventricular fibrillation, the core body temperature was decreased on average by 1.20°C upon administration of 4ºC normal saline while in patients without ventricular fibrillation, the mean core body temperature was lowered by 1.30°C after the initiation of therapeutic…

In case of pacing the coronary heart rhythm from ventricular conduction device, the price slows right down to 30-40/min and QRS complexes on the ECG are wider than 120 ms. In ventricular traumatic inflammation the depolarization of cardiomyocytes is caused by several mechanisms – reentry, induced hobby, ectopic foci of excitation or mixture of these. In ventricular traumatic inflammation (VF) the heart paintings is useless, fibrillating ventricals are not pumping blood and the circulation stops.…

from Stonewall hospital in Lexington in order to receive pulmonary care. Though she was admitted for unspecified dementia without behavioral disturbances, she was originally hospitalized at Stonewall since September 21, 2016 for atrial fibrillation with a low ventricular response rate, and dyspnea. She has co-morbidities of Parkinson’s disease and Lewy body dementia, and will be discussed first with the inclusion of signs, symptoms, related lab tests, and diagnostic values. She also has a long…

cardiomyopathy or broken-heart syndrome. The name takotsubo comes from the similarities between the left ventricle and the shape of a Japanese octopus trap. Stress is a common occurance in cases of TC. In approx- imately 70-80% of cases, transient left ventricular systolic dysfunction with apical akinesis and compensatory basal hyperkinesis characterized. The other 20-30% of cases are atypical forms that involve basal or midventricular hypokinesis with apical sparing. A significant…

however, the underlying diseases can be treated. The backbone treatments for restrictive cardiomyopathy include diuretics, vasodilators, ACE inhibitors and anticoagulation therapies. Beta blockers help to improve ventricular relaxation and diastolic function, as well as increase ventricular filling time. Diuretics are used to lessen preload and help ease pulmonary congestion. ACE inhibitors also help to improve diastolic filling, but should not be used in patients with amyloidosis as it may have…

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…

GERD: Gastroesophageal Reflux Disease is most commonly known as “heartburn”. It refers to the back flow of gastric or duodenal contents or both into the esophagus and past the lower esophageal sphincter, without associated belching or vomiting. The reflux of gastric contents causes acute epigastric pain, usually after a meal. Common causes are: food, alcohol, or cigarettes, hiatal hernia, increased abdominal pressure (such as with obesity or pregnancy), medications, nasogastric intubation for…

of AF often described as a rapid “fluttering in the chest,” with irregular “fluttering” that suggests AF, atrial flutter, or tachycardia with variable block.11 In patients with chronic atrial fibrillation, in-office exercise such as a brisk walk in the hallway may reveal an intermittent accelerated ventricular response as the cause of the palpitations.11 The clinician should look for signs of hyperthyroidism, or signs of stimulant drug use such as dilated pupils and skin or nasal septal lesion11…

The incidence of atrial fibrillation increases with age which can causes serious problems in older people, leading to stroke and/or heart failure. Risk factors include hypertension, previous ischemic stroke, transient ischemic attack or other thromboembolic event, coronary heart disease, diabetes mellitus, heart failure, and mitral valve disease (Holding et al., 2009). In addition to advanced age, patients that are obese, of the Caucasian race, or have a history of excessive alcohol use are at…
