with hypertrophic cardiomyopathy. Atrial fibrillation is a heart rhythm in which the top part of the heart has disorganized electrical activation. This sends multiple‚ fast‚ irregular impulses to the left ventricle causing the heart to beat rapidly and irregularly. Symptoms such as palpations‚ shortness of breath‚ or decreased exercise capacity may occur. The most dangerous rhythms from the left ventricle are called ventricular tachycardia fibrillation‚ which can cause death. In my opinion‚ the

measures to determine the amount of force pushing against artery walls when the heart is at rest and contracting. Systolic BP (SBP) reflects the change in artery pressures related to ventricular SV (McLean‚ 2015). In this case study‚ the underlying arrhythmia for the patient was determined to be atrial fibrillation (AF). Patient’s last BP measure was 80/50. Will this new diagnosis improve the patient’s BP? Not really. While adenosine may slow the electrical conduction rate of the heart‚ the pathophysiology

CAD is thought to begin with damage or injury to the intimal layer of coronary artery‚ sometimes as early as childhood. The damage may be caused by various factors‚ including: smoking‚ hypertension‚ hypercholestromia‚ diabetes or insulin resistance‚ radiation therapy to the chest‚ as used for certain types of cancer‚ and sedentary lifestyle. Once the intimal layer of coronary artery is damaged‚ fatty deposits (plaques) made up of cholesterol and other cellular waste products tend to accumulate at

Atrial fibrillation is the most common cardiac arrhythmia that is associated with a reduced quality of life and an increased number of adverse outcomes such as stroke‚ heart failure‚ increased number of hospitalizations and mortality. Prevalence in developed countries is currently 1.5-2% of the general population‚ with the incidence steadily rising. Hence‚ prevalence is estimated to at least double in the next 50 year as the population ages. It has become a big deal for the health care system in
