Cardiac Surgeon Cardiac surgeons treat valvular heart diseases such as valve stenosis or vessel insufficiency‚ ischemic heart disease‚ coronary artery disease‚ atherosclerosis and congenital defects. They treat these diseases by repairing or replacing heart valves‚ widen clogged arteries‚ repair aortic aneurysms‚ implant defibrillators and pacemakers‚ and perform double‚ triple‚ quadruple‚ and sometimes even quintuple heart bypasses. Cardiac surgeons must complete internships and residency requirements

M01 11 February ‚ 2012 Cardiac Arrest General Purpose: To inform Specific Purpose: To inform the audience about what is happening in the body during cardiac arrest and what to do if they witness a cardiac event. Central Idea: Bystander CPR and use of an AED‚ or automated external defibrillator‚ is the greatest predictor of survival for a person in cardiac arrest. The majority of the general public feel unprepared or unqualified to assist a person in cardiac arrest. Hands only CPR is a

Sudden cardiac death happens more these days. There are so many people alone in the United States who just stops breathing with no heart disease involved. So why did their heart stop? There are so many researchers out there trying to figure out the underlying cause of these people who this happen to. There can be other reason why a person’s heart can stop without having a cardiac disease. A person’s body may store minerals that control the arrhythmia of the heart to act a different way.

recognize normal and abnormal cardiac rhythms‚ called dysrhythmias‚ is an essential nursing skill. • Four properties of cardiac cells (automaticity‚ excitability‚ conductivity‚ and contractility) enable the conduction system to start an electrical impulse‚ send it through the cardiac tissue‚ and stimulate the myocardial tissue to contract. • The autonomic nervous system plays an important role in the rate of impulse formation‚ the speed of conduction‚ and the strength of cardiac contraction.

The cardiac pump is thrown out of gear‚ and the last of its vital energy is dissipated in a violent and prolonged turmoil of fruitless activity in the ventricular walls." He also describes the electrical stimulation of the heart in cases of "fatal syncope" in man. "A single induction shock readily causes a beat in an inhibited heart‚ and a regular series of induction shocks (for example‚ sixty or seventy per minute) gives a regular series of heartbeats at the same rate."

Q1: Causes of atrial fibrillation A 58-year-old woman comes to the emergency department with a-3-days history of difficulty breathing and unpleasant feeling of rapid and irregular heartbeats. Additional history taking reveals that she has a 7- week-history of unintentional weight loss‚ anxiety‚ and difficulty sleeping at night. She smokes 10 cigarettes per day for the past 15 years. Her blood pressure is 100/55 mmHg‚ temperature is 36.5 °C and her pulse is irregular at a rate of 140 to 150 beats
