Cardiac electrophysiology

defined as a core body temperature of 35°C (95°F) or lower. It should be treated as a medical emergency. Shivering is an early sign. Patients with severe hypothermia (core temperature less than 32°C) may appear dead or may have hypotension, apnea or cardiac arrhythmias. Hematologic, respiratory, renal and endocrine abnormalities are common in severe hypothermia.” 1 Hypothermia can result from many different scenarios. A common…

Saving Lives, Outside the Hospital (Informative Speech) Bradley Dryden, Western Governor's University General purpose: To inform Specific purpose: To inform the general public of the need and efficacy of compression-only cardiopulmonary resuscitation. Thesis statement: Any attempt to perform CPR is better then no attempt at CPR. I. Introduction Imagine this situation. You are at a family dinner. Everyone is enjoying conversation after the meal, and you notice uncle Leroy with a worried look…

Patients after Open Heart Surgery Wound infections can occur in adult patients who have open heart surgery, whether via bacteria or virus. According to the Hussain, Mannan, and Ali (2012), “sternal and mediastinal infection is a serious complication of cardiac surgical procedures performed…

opened his eyes, was sent to hospital, and was released a few days later. Another story includes Ralph Harms, 78, and his son Joe, and his friend Doug Green. After a great shot, he exclaimed “Yeah baby!” and collapsed right there on the course from cardiac arrest. Luckily four years ago, Joe was shown by Ralph how to do chest compressions. While Doug called 911, Joe continued, while performing CPR, Ralph’s heart started and stopped 3 times. He would not have survived and spent 3 days in a…

us to gather new facts about the human body. Therefore, to completely understand how these cells affect our bodies, one must first be aware of the different types of muscles, which include skeletal, cardiac, and smooth muscles. Skeletal muscle is a muscle that is connected to the skeleton, while cardiac muscle, also called myocardial, is the muscular tissue of…

exercise can strengthen cardiac and respiratory variables by having them become more efficient (Salmon et al., 2003). As one exercises, work rate increases and the body must match the necessities of the respiratory and…

The results from the first experiment confirmed the hypothesis, to a certain extent, in that increasing stimulus strength will increase the force generated by the gastrocnemius muscle and visa versa till 0.2V, where the force germinated starts to decrease. As shown in Table 2 and Figure 2, the strength of the stimulus started from 0.00 V to 1.00V with 0.05 V and 0.10V intervals. At 0.10V the force generated by the muscle increases rapidly from 0mN to 288.33mN. The force generated by the muscle…

Intrinsic Cardiac Activity: The first peak of the electrocardiogram graph corresponded to the atrial contraction of the heart. The second peak of the electrocardiogram graph corresponded to the ventricular contraction of the heart. The third peak observed corresponded to the relaxation of the heart. Frank-Starling Mechanism: There was no significant trend observed in ventricular contractile force in response to increasing imposed length of the heart (Fig 1a). A maximum ventricular contractile…

mechanism of death are congestive heart failure, cardiac arrhythmias. B. What exactly does mechanism of death tells. Mechanism of death basically tells what caused the body to actually shut down or expire. For instance a gunshot to the head can cause a person to bleed to death or cause internal bleeding. Blunt trauma to the back of the head can cause internal blood flow into the lungs causes a person to drown to death from their own blood. If a person has a cardiac arrest and passes away the…

Mylan Pharmaceuticals has been in the spotlight lately, but not exactly in a positive way. The media and consumers have made it known that they don’t appreciate excessive price hikes in one of the many drugs Mylan produces. The EpiPen is designed for patients who have a severe allergic reaction to some substance or extreme cases of asthma attacks. Unfortunately for those that need the drug, prices have increased from $57 in 2007 to about $616 for a two-pack today—an increase of 1,080%. Just…
