What happened to the R-R interval and heart rate after exercise? After exercise the R-R interval increased steadily from 0.48 to 0.68 seconds‚ while the heart rate BPM decreased steadily from 123 to 76; both trending back towards the resting values. What happened to the T-P interval during exercise? Outline what this means for ventricular filling time. During exercise there was a significant drop in the T-P interval which then steadily increased when exercise was completed. The T-P interval represents

conditions could affect one’s heart rate. In the life of a human‚ the heart beats approximately forty-five million times per year varying based off of factors like age‚ gender‚ physical activity level (1). Furthermore‚ throughout the course of a day‚ the heart can vary in its heart rate from a number of different environmental changes such as prolonged standing‚ altered breathing (inhale vs. exhale)‚ and jolts of excitement such as being startled. Relating to the heart rate of an individual is their

Introduction In this lab‚ I looked at how exercise affects a person’s heart rate (BPM)‚ systolic pressure‚ diastolic pressure‚ and Mean Arterial Pressure (MAP). Heart rate is measured by beats per minute while systolic and diastolic pressure are measured by millimeters of Mercury. I found the MAP by the following equation‚ MAP= Diastolic Pressure + ⅓(Systolic-Diastolic). We found out that heart rate and systolic pressure were highest right after and during exercise‚ while diastolic pressure and

TITLE: Effect of the caffeine on the heart rate OBJECTIVE: To investigate the effect of the caffeine on the heart rate of living organisms. INTRODUCTION: * Daphnia Daphnia are small‚ planktonic crustaceans‚ between 0.2 and 5 mm in length. Daphnia are members of the order Cladocera‚ and are one of the several small aquatic crustaceans commonly called water fleas because of their saltatory swimming style (although fleas are insects and thus only very distantly related).

Coronary artery disease is also known as atherosclerosis disease‚ coronary heart disease‚ or ischemic heart disease. It is the most common type of heart disease.

ANATOMY AND PHYSIOLOGY OF HUMAN HEART The human heart is a cone shape‚ hollow‚ muscular organ located in the mediastinum between the lungs. It is a about the size of an adult fist. The heart rests on the diaphragm‚ tilting forward and to the left in the client’s chest. Each beat of the heart pumps about 60ml of blood‚ or 5L/min. During strenuous physical activity‚ the heart can double the amount of blood pumped to meet the increased oxygen needs of the peripheral tissues. ANTERIOR VIEW
