Premature ventricular contraction

the leading cause of sudden cardiac death, with 400,000 victims a year. There are four main types of arrhythmia, premature beats, supraventicular arrhythmias, atrial fibrillation, and bradycardia. Premature beats is the most common type and harmless.Majority of the time it happens naturally or due to the fact of being over stressed, over training, and or too much caffeine. Premature beats usually do not cause any symptoms therefore the reason it is harmless. Rare occasion of a symptom…

generalized tonic-clonic seizures. In relation to ST-segment elevation, cardiac ischemia is possible; however it is unlikely to occur in conjunction with uncomplicated seizures. (92) Ventricular arrhythmias are affected in susceptibility by myocyte myofilament damage and arrhythmogenic alterations. Lethal ventricular arrhythmias are at an increased risk for occurrence post-seizure with prolonged seizure activity. (Bealer) Respiratory changes occurring ictally are associated with tonic-clonic…

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…

is a treatment for the heart disease called arrhythmia. An Arrhythmia is a problem with the rate or rhythm of the heartbeat. During an Arrhythmia, the heart can beat irregularly (either too fast or too slow). There are four types of Arrhythmia. premature arrhythmia – are extra heartbeats that begin in one of your hearts two lower pumping chambers (ventricles). These heartbeats disturb your normal heart rhythm which causes your heart rate to increase. supraventricular arrhythmias – is a fast…

plot through an ectopic from atrial tissue, since the premature atrial depolarization will reset the sinus cadence called a premature atrial complex (Blesi/Jones/Lewis pg136). The P waves is when the valves between the atria and ventricles open 70% of the blood in the atria and the atrial contraction is only required the final 30% (Merriam-Webster’s collegiate dictionary The University of Nottingham). The QRS complex represents the ventricular depolarization and it can be comprised of any…

This patient is a 70-year-old male who required inpatient hospitalization due to concerns for acute exacerbation of congestive heart failure. He was presented to the emergency department due to the complaints of pain in the sub sternal/epigastric region accompanied by productive cough which worsen by movements. The pain was described as mild to moderate, constant and dull. His past medical history was suggestive of cardiomyopathy and hypertension. It was noted that he underwent cardiac…

heart rate. Not only is the client tachycardic, with a heart rate of 124 beats per minute, but the electrocardiogram (EKG) was previously showing ST elevation in two anterior leads. Currently, the EKG is showing that MK is experiencing premature ventricular contractions. The nurse should also be concerned about the client’s lab reports. While the client’s creatinine phosphokinase (CPK), blood urea nitrogen (BUN), and creatinine levels are within normal limits, her CPK-MB and troponin 1 levels…

definition , PPCM includes cardiac failure in the last trimester of pregnancy or within six months of delivery, absence of an identifiable cause for the cardiac failure, absence of recognizable heart disease before the last month of pregnancy, and left ventricular (LV) dysfunction (ejection fraction of less than 45% or reduced shortening fraction). The detection of this heart diease in pregnancy…

TERMINOLOGY CLINICAL CLARIFICATION 1 • Life-threatening condition characterized by the inability of the pulmonary system to meet the metabolic demands of the body with respect to oxygenation of the blood and systemic organs and/or CO2 elimination • May be accompanied by ventilatory failure 7 • Develops within minutes or hours as opposed to chronic respiratory failure that develops over several days, weeks or years CLASSIFICATION 2, 1 • Classification is mainly based on arterial blood gas (ABG)…

controlled two-part pumping is necessary to supply blood to the entire body. This supply rate is regulated by the pacemaker region of the heart, in the right atrium (chamber), by detecting a diffusion of ions, causing a rhythmic electrical impulse. Ventricular fibrillation is an irregular heart rate caused by malfunctions of these impulses that can be treated, and…
