Introduction: In this activity each group has a member record their electrical activity of the heart with electrodes. The electrodes will be put on three different locations on the body, the right anterior forearm at the wrist, and on the medial surface of each leg, superior to the ankle. Since the electrodes will not be placed directly over the heart artifacts can result from the recording of unwanted skeletal activity. Therefore the member has to be still, cannot laugh or talk, and when in the sitting position the member needs to keep arms and legs steady and relaxed. There were three different conditions they had to go through to measure the electrical activity of their heart. The first condition was the member had to lye down, the second condition was after the subject sits up and breath normally, and the third condition was, after the group member has exercised (jumping up and down) and breathing deeply.

Background: The heart consist of four chambers, there is the right and left atrium which are the top two chambers, then there’s the ventricles which are thee bottom …show more content…
Once the ECG is centered for analysis, click the I-beam cursor, using the highlighting function and deltaT computation, measure the duration of every component of the ECG waveform. Highlight each component of one cycle. Observe the elapse time, and record the data under Cycle 1 in Segment 1 Elapsed Time Char. Then view two additional cycles in segment 1. Record elapsed time for every component of cycle two and cycle 3 in Segment 2 Elapsed Time Chart, and calculate the means. For Segment 3 Elapsed Time for ECG Components use the same instruction as above and record the data under Cycle 1, in Segment 3 Elapsed Time chart. Analyze two other cycles in segment 3. Record the elapsed time for each component of cycle 2 and cycle 3 in Segment 3 Elapsed

INDICATORS OF AN ASC: Physiological (Bodily) * Heart rate (ECG) - may increase during certain ASC involving arousal, but generally will decrease - Eg. Sleeping, meditating * Body temp – Doesn’t change much, but drops about 1 degree whilst sleeping, if it rises too much, resulting in a fever, an ASC may be induced * Galvanic skin response – Indicates skins level of arousal by measuring electrical conductivity - Eg.

...HEART RHYTHMS * 0.4 sec is the PR wave (it is actually the P-Q wave but called the PR wave) and it should be ≤ 0.20 sec. If it’s ≥ than that it indicates 1° heart block. * NSR: normal sinus rhythm, contraction originates from SA node and beats at 60-100 bpm * Sinus (atrial) Bradycardia: SA node discharges at < 60 bpm. TREATMENT is atropine and pacemaker if they become symptomatic. Usually the contractions are irregular but the same distance apart so they are irregular-regular * Sinus Tachycardia (atrial dysrhythmias): SA node discharges at > 100 bpm. Regular but fast; they won’t have heart block because the SA node is firing too rapidly. TREATMENT is BB or CCB to ↓ HR and BP * PAC (Premature Atrial Contraction): impulse travels across atria via abnormal pathway, creating a disturbed P wave. Contraction originates from ectopic focus in atrium other than the SA node. Caffeine and diet pills predispose people to these but they don’t adversely affect health. TREATMENT is none. * Atrial Flutter: atrial tachycardia resulting in recurring, regular sawtooth flutter waves. The ratio of atrial to ventricle contractions is 3:1. TREATMENT is synchronized cardioversion (like defibrillation but the less Joules, 150-200 vs 300, and you must push the “sync” button to synchronize the energy so as to not direct it onto the T wave and send the patient in V-fib) and ablations. * Valve Replacement: patient must be put on blood thinner afterwards and must be anticoagulated...

...pain that began 2 hours ago. The patient describes the pain as pressure in the center of his chest. He rates his pain 7/10. He reports the pain is now radiating down his left arm and through to his back, he is diaphoretic, and complaining of shortness of breath. He denies nausea or vomiting. Mr. Smith reports no previous history of chest pain or pressure. He smoked one pack of cigarettes daily for 13 years but quit smoking last year. He denies a family history of heart disease. Upon initial examination he did not have jugular venous distension, no carotid bruits, normal S1 and S2 with an S3 present. No S4 or murmurs auscultated. Lung sounds clear to auscultation bilaterally, bowel sounds normal, all pulses palpable 2+/4, no edema present. Diagnostic data: BP: 165/98 mmHG HR: 96 bpm RR: 30 breaths/min Temp: 37 C SaO2: 96% with 2L/min O2 per nasal cannula Wt:100 kg A 12-lead ECG was performed in the emergency room showed: Normal Sinus Rhythm (NSR) with frequent premature ventricular contractions. ST segment elevation in Leads 1, aVL, and V2 through V6 (3mm). ST segment depression in Leads III and aVF. Q waves in V2 through V4.

Biometrics

...Summary. Various anthropometric studies have been conducted in the last decade in order to investigate how different physiological or behavioral human characteristics can be used as identity evidence to prove the individuality of each person. Some of these characteristics are: face, eyes, ears, teeth, fingers, hands, feet, veins, voice, signature, typing style and gait. Since the first biometric security systems appeared in the market, an increasing demand for novel techniques that will cover all different scenarios, has been observed. Every new method appears to outmatch some of its competitors but, at the same time, presents disadvantages compared to others. However, there is still no method that consists a single panacea to all different scenarios and demands for security. This is the reason for which researchers are on a continuous effort for more efficient and generic biometric modalities that can be used in various applications. In this chapter, emerging biometric modalities that appeared in the last years in order to improve the performance of biometric recognition systems, are presented. The presented methods are divided in two major categories, intrusive and non-intrusive ones, according to the level of user nuisance that each system sets off. 1 Introduction Biometric recognition is a well-known research area that aims to provide more efficient solutions to everyday growing human need for security. Biometrics refers to methods that can be used for uniquely recognizing...
