Physiology, Health & Exercise Lesson 3 ECG Tracings ECG Electrocardiogram Easy to carry out Graphic record of electrical activity of the heart as it contracts and relaxes Used to check for problems with the heart Also used to check condition of heart shows abnormal heart beats Areas of damage I...
the apical beat (point of maximum intensity) shifts laterally. Overall, the heart size increases by approximately 12%, which results from both an increase in myocardial mass and intracardiac volume (approximately 80 mL). Vascular changes include hypertrophy of smooth muscle and a reduction in collag...
If you were to dissect the heart of a top endurance athlete you would find that the left ventricle walls were a lot larger than the right What is this called? Cardiovascular ADAPTATIONS This adaptation is called CARDIAC HYPERTROPHY Cardiac hypertrophy is the first adaptation to the cardiovascular ...
Cardiac outputrefers to the volume of blood pumped by each ventricle of the heart per unit time. Specifically, it is defined as the volume of blood pumped by the leftorright ventricle every minute. Cardiac output is calculated by multiplyingheart rate(number of heartbeats per minute) by the ...

In several populations the presence of high levels of Lp (a) has been shown to be a strong independent risk factor for the development of coronary heart disease. The function of Lp (a) or apo (a) is unknown; it is possible that Lp (a) does not interact with the LDL receptor as ...
Mean and diastolic blood pressure (MBP and DBP) and heart rate (HR) were also measured at each visit. A novel parameter, PAT normalised for HR of 75 (PAT-75), was also computed. PAT and PAT-75 were compared for these visits using repeated measures analysis of variance. The int...
