Cardiovascular Emergencies Review cardiac anatomy (page 402-404) Common cardiac Problems: Cardiac Compromise-Chest pain or discomfort that is related to the heart usually comes from ischemia- lack of oxygen due to partial or complete blockage of the artery Ischemic heart disease- disease involving insufficient blood flow to one or multiple parts of the heart Arteriosclerosis- build up of calcium and fatty tissue (plaque) inside the walls of the artery: this buildup can eventually cause an occlusion- blockage of blood flow Lumen- inside diameter of the artery Acute Myocardial Infarction (AMI)- a heart attack: dead cardiac tissue as a result of an ischemic episode in which blood flow was not restored in time for tissue to repair itself Cardiac arrest- the hearts inability to pump Angina pectoris- pain that is caused when the heart muscle does not get enough blood for a brief period of time, this can also be caused by a spasm of the artery Signs and symptoms of a heart attack: page 408-409 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Weakness Nausea Sweating Chest pain/discomfort/pressure Pain or discomfort in the jaw/arms/back/abdomen/neck Sudden arrhythmia (abnormal heart beat) Syncope- fainting Shortness of breath or dyspnia Pulmonary edema Sudden death The pain of a heart attack: page 409 1. May or may not be caused by exertion 2. Does not resolve in a few minutes (last for 30 minutes to several hours) 3. May or may not be relieved by rest or nitro Physical findings of a heart attack (page 409): 1. Pulse a. Increase rate b. Irregular rhythm 2. Blood pressure may or may not be effected by heart attack 3. Respiration a. Usually normal b. CHF may cause them to become rapid and labored 4. General appearance a. Frightened b. Nausea/vomiting c. Cold sweat/ clammy d. Gray/ashing or bluish skin 5. Mental status a. Overwhelming feeling of impending doom Heart rhythms and rates: page 410 Tachycardia- Bradycardia- Ventricular tachycardia (VT) – sometimes referred to as SVT (super ventricular tachycardia)- Ventricular fibrillation (V-Fib)- Asystole- Cardiogenic shock (page 410-411) CHF(Page 412): Congestive heart failure- when the heart muscle can no longer keep up with the return flow of blood Dependent edema- collection of waist fluid in the body (usually in the feet, legs, or chest) Administration of nitroglycerine page 416-417: 1. 2. 3. 4. 5. 6. Obtain order from medical control (on or off line) Ensure the patient’s blood pressure is greater than 100 systolic Question the patient about the last time they took this medication Ensure the patient has not taken any sexual enhancements medications Ensure the patient is sitting down incase fainting occurs Check the 4 rights 7. 8. 9. 10. 11. 12. 13. 14. Have the patient open their mouth and lift his or her tongue Your or the patient place the prescribed dose under their tongue Tell the patient not to chew or swallow (if medication is in tablet form) Alert the patient of the possible side effects Wait 5 minutes (take them to the truck) Recheck vitals and QRS Document the time dose and effects of the medication Transport immediately Heart surgeries and pacemakers: page 418-420 Bypass- Stint- Catherization- Pacemaker- Internal defibrillator- Review protocol for cardiac arrest and use of an AED 423-430
