But through modern research we have learned that diseases are caused by genetics‚ viruses‚ and other bodily problems

immediately before initiation of contraction to completion of contraction (i.e.‚ SV = end diastolic volume to end systolic volume) b. It is determined by contractility (i.e.‚ SV = [end diastolic volume]-[end systolic volume])‚ preload (amount of myocardial stretch at end of diastole)‚ and afterload (resistance ventricles must overcome to empty their contents) c.

Introduction: This case study discusses the management of a 68 year old male who presented with chest palpitations secondary to rapid atrial fibrillation. Atrial fibrillation is a common cardiac arrhythmia with serious complications if not treated correctly. This essay will discuss the initial clinical presentation of the patient and examine the management and outcome of the interventions applied. The significance of atrial fibrillation including its pathophysiology and aetiology will also be discussed

Treating Heart Failure When a patient’s heart is no longer able to pump a sufficient amount of blood around the body‚ they are referred to as having heart failure. The heart muscle has been damaged or overworked and is therefore unable to pump as effectively as before. Coronary heart disease is the most common cause of heart failure‚ cardiomyopathy and hypertension are also implicated (Peterson et al‚ 2002). Heart failure can present acutely or chronically. Chronic heart failure tends to worsen

This condition is the most significant underlying cause of heart failure‚ coronary artery disease‚ strokes and infarction resulting from ischaemia of the heart‚ brain or extremities.

It is most important for the EMT to remember that the suicidal patient may be homicidal as well. Successful treatment of a stroke depends on whether thrombolytic therapy is given within 3 hours after symptoms begin. You are transporting a male with “tearing” abdominal pain. You are approximately 30 miles away from the closet hospital. During your reassessment‚ you determine that the patient’s condition has deteriorated significantly. You should consider requesting a rendezous with ALS.
