The EKG simply picks up electrical impulses; it does not read mechanical activity. When a patient has ischemia, injury or necrosis to the heart muscle, the electrical impulses change in the area involved. Nurses can analyze the electrical changes and determine if they indicate mechanical dysfunction. • The EKG is simply a volt meter that picks up electrical signals. Therefore, anything that interferes with electrical conduction can cause changes in the EKG. These variables can be divided into three main categories: – 1) physiological variables not specific to the heart (ie. pulmonary embolism, increased intracranial pressure) – 2) electrical interference (ie. poorly placed lead) – 3) ischemia, injury, or infarction 5 Steps to 12 Lead Interpretation 1. Assess regularity and speed 2. Look for signs of infarction 3. Present in >1 lead, but not all? 4. Assess associated conditions 5. Correlate with clinical condition • V1 &V2 look at right ventricle • V3 & V4 look at septum and lateral left • ventricle • V5 & V6 look at anterior/lateral left vent. 86 89 90 91 92 • http://nursebob.com/ • http://www.usfca.edu/fac_staff/ritter/ekg.htm • http://ems-safety.com/12-lead-ekg.htm Rhythms for Cardioversion • A-fib • A-flutter • Supraventricular tachycardia 94 Electrical cardioversion • The difference between defibrillation and cardioversion is that the countershock is synchronized to the QRS complex which allows the electric current to be delivered after the R wave and before the the period associated with the T wave. It is the treatment of choice if the patient has a hemodynamically unstable tachydysrhythmia. It is the primary treatment for most tachydysrhythmias. It is used for the treatment of unstable ventricular tychardia with a pulse, since this often leads to ventricular fibrillation, atrial flutter, atrial fibrillation, and most tachycardias. With cardioversion the potential exists to prevent this life-threatening dysrhythmias. • Cardioversion may either be a planned or emergent procedure. If done as an elective procedure, the patient should be sedated before cardioversion begans. Of course, the institutions policies and procedures for conscious sedation should be followed. • Properly done cardioversion will correct the patient’s dysrhythemia with minimal discomfort and maximum safety. Chemical cardioversion • Indication A. Considered to be an effective alternative to electrical cardioversion for Rapid conversion of atrial fibrillation and atrial flutter. B. Ibutilide is moderately effective in causing prompt conversion to sinus rhythm with greater efficacy in patients who have atrial flutter. • 2. Action. A. Ibutilide prolongs action potential duration by activating a slow inward current, largely carried by sodium ions. B. Blocks the rapidly activating component of the delayed rectifier potassium current. C. No significant effect on heart rate, PR interval, or QRS interval D. Potential prolongation by Ibutilide leads to an increase in atrial and ventricular refractoriness in vivo. E. No clinically significant effect of Ibutilide to lower blood pressure or worsen congestive heart failure. F. Route of elimination: hepatic. • 3. Administration. A. Ibutilide is available in 10 mL vials containing 0.1 mg/mL (1 mg total). B. For intravenous administration, the recommended dose of Ibutilide is 1mg over a 10 minute period in patients weighing > 60 kg C. Patients weighing < 60 kg, the recommended dose is 0.01 mg/kg initially, with a second dose of the same strength 10 minutes later if necessary. D. Ten minutes after the end of the initial infusion, a second 10 minute infusion of equal strength can be given if the arrhythmia has not terminated. • Cautions. A. Prolong ventricular repolarization B. Carries a risk of excessive QT prolongation C. Acquired long-QT syndrome D. Associated polymorphic ventricular tachycardia (torsade de pointes) E. Careful patient selection and clinical monitoring during drug administration. • 5. Contraindications. A. QTc interval exceeding 440ms B. Bradycardia C. Electrolyte disturbances D. Other QT-prolonging drugs • 6. Adverse Effects. A. Ventricular tachycardia B. Premature ventricular complexes C. Hypotension D. Bundle branch block E. Atrioventricular • Post cardioversion care: • 1. generally the care for a patient tells cardioversion is the same as for the fibrillation. • 2. If it is a elective procedure, digoxin is usually withheld for 48 hours prior to cardioversion to prevent dysrhythmias after the procedure. • 3. Airway patency should be maintained and the patient state of consciousness should be evaluated.

The first part of the word, "electro", means electrical, and the second part of the word, "physiology", means function. Therefore, an electrophysiology study is simply a study of the electrical function of your heart. This study will provide specific information about your arrhythmia. Once the doctor has this information, it is easier to select the appropriate treatment for you • A small intravenous (IV) catheter may be placed in a vein in your hand or arm. This may be used to continuously administer fluids, or it may be covered with a cap for intermittent use. The purpose of this IV is to provide the nurses and doctors with a quick means of administering medications, should your heart rhythm abnormality occur. • An EP team doctor will explain why the procedure is necessary and what risks are involved for you. The degree of risk varies with each person and is related to your specific condition. After discussing this information, you will be asked to sign a consent form to indicate your permission for the study • Prior to the EP study, your skin will be washed with a special soap and the hair shaved from potential catheter insertion sites. The most common site used is the groin, or the area at the crease of the leg about midway between the center of your body and your hip. Occasionally the forearm, neck or collarbone areas are used. The purpose of this washing is to provide a clean insertion site and reduce the chance of infection • You will be asked not to eat or drink anything after midnight the night before your test. If your test is not scheduled until later in the day, you may have a clear liquid breakfast, after which you must not eat or drink. You may take your morning pills with a sip of water. All your medicines will be reviewed, and some may be withdrawn prior to the test. • You will not receive anything to put you to sleep before this test. It is important for you to describe sensations you have during the test to the staff in the EP laboratory. Medicines that sedate people may interfere with the ability to find the abnormal heart rhythm, but each patient is treated individually and you may discuss this issue with the EP team physicians and nurses. • If you have dentures and they are tight-fitting, you may wear them during the study. You may also wear your glasses and watch if you wish. You should wear a hospital gown without bottoms, but may wear your socks if you wish. You should use the bathroom just before going to the lab because it may be several hours before you return to your room. A bedpan or urinal will be made available to you, should you need it during the study. It is sometimes necessary to insert a catheter into the bladder for continuous drainage during longer procedures. If this is planned, it will be inserted early in the procedure. An initial EP study takes an average of two and a half hours; however, they may range from one to six hours. Your family members can wait in your room or in one of several lounges, and will be notified when your study is finished. • Catheters are flexible hollow plastic tubes, much like the intravenous catheter in your arm or hand, only larger to be placed in larger central veins. These are placed most commonly in veins, but occasionally in arteries, depending upon the type of study you are undergoing. Usually, two catheters are used, but, depending on the type of study to be performed, as many as five can be used. The purposes of these catheters are both to provide access to the vein or artery, for placement of pacing wires into the heart, and for administration of medications or fluids. • Long, thin, flexible wires, referred to as pacing wires, or intra-cardiac catheters, are advanced through the IV catheter and up into the heart chambers under the guidance of an x-ray camera (see diagram). These pacing wires are used to both record the electrical patterns from inside the heart and to "pace" the heart. Pacing the heart is delivery of very small amounts of electricity to the heart muscle through the tip of the catheter. This causes a heart beat, and allows the electrophysiologist to compare your heart's response to paced beats to already known normal responses. Approximately half of the patients undergoing this procedure are aware of each heart beat, and therefore, feel their heart speed up, slow down, or "skip a beat". Many other people are completely unaware of the pacing procedure. • If an arrhythmia is provoked by the pacing, you may feel some of the same symptoms that caused you to seek medical attention. Please tell the EP staff what you feel. Let them know if you have shortness of breath, dizziness, light-headedness, or chest discomfort. A member of the team will be by your side and talking with you at all times. • After the test, the catheters will be removed. Firm pressure will be applied over the puncture site for approximately 15 minutes. This is necessary to prevent any bleeding from the insertion site. You will then be taken to your hospital room, or the EP recovery area. • Flat bed rest is necessary for two to eight hours after the study. During this time, it is important to keep the leg or arm used in the procedure straight to prevent bleeding from the insertion site. After the specified amount of rest, you will be able to resume your previous activity level. • Your nurse will be in the room frequently during the first hour after the study to take your blood pressure, heart rate, and check your insertion site for signs of bleeding. The pulses and temperature of your feet will also be checked. • You will be instructed to apply pressure firmly to the insertion site if you cough or sneeze and while using the bedpan or urinal. If you should notice any bleeding at the site, notify your nurse immediately. If your back becomes uncomfortable, do not hesitate to ask the nurses for pain medications. • You will be able to resume your previous diet and your nurse or family members can help you eat while you are reclining in bed. Bundle Branch Blocks: Diagnosed with 12 lead EKG: most common cause: acute MI • Right bundle branch block: • - impulse travels through left ventricle first, then activates right ventricle (gives am “M” shaped complex • Left bundle branch block: • --impulse first depolarizes right side of heart then the left ventricle (gives deep, wide “V” shaped complex 114 Bundle Branch Blocks: • Risks: can deteriorate to 3rd degree block • then treat with atropine or pacemaker • Pt can be asymptomatic until progresses 115 116 Hyperkalcemia 117 • Practice Slide 1 120 Slide 2 121 Slide 3 122 Slide 5 123 Intro to ACLS Primary Survey • Airway: Open airway, look, listen, and feel for breathing • Breathing: If not breathing slowly give 2 rescue breaths. If breaths go in continue to next step. • Circulation: Check the carotid artery (Adult) for a pulse. If no pulse begin CPR. • Defibrillation: Search for and Shock V- Fib/Pulseless V-Tach Adult ACLS Secondary Survey ABCDs (abbreviated) • Airway: Intubate if not breathing. Assess bilateral breath sounds for proper tube placement. . • Breathing: Provide positive pressure ventilations with 100% O2. • Circulation: If no pulse continue CPR, obtain IV access, give proper medications. • Differential Diagnosis: Attempt to identify treatable causes for the problem. AED • An AED is a device used in cardiac arrest, or sudden cardiac death, when the heart’s electrical activity is disorganized and there is no effective pumping of blood. The AED is capable of recognizing the heart's electrical activity, and determining if an electric shock is required. If the shock is needed, a voice prompt in the AED is activated, telling the rescuer to push a button to deliver the shock • http://acls.net/quiz/mi_stroke_1.htm stress • Common responses can include: – Feeling a sense of loss, sadness, frustration, helplessness, or emotional numbness – Experiencing troubling memories from that day – Having nightmares or difficulty falling or staying asleep – Having no desire for food or a loss of appetite – Having difficulty concentrating – Feeling nervous or on edge Teaching to cope • Reach out and talk. Create opportunities to talk, but do not force them. Try asking questions like, what do you think about these events, or how do you think these things happen? After a traumatic event, it is important for the patient/family to feel like they can share their feelings and to know that their fears and anxieties are understandable. • Express yourself. Your patient may be feeling different emotions at different times. Sadness. Anger. Fear. Confusion. These feelings are normal reactions to this situation. Don't be afraid to allow your client to express how he or she feels and share your feelings with them. • Watch and listen. Be alert for any change in behavior. Is the patient sleeping more, or less? Are they withdrawing from friends or family? Are they behaving in any way out of the ordinary? This may show that they are having trouble coming to terms with this event. Recognizing even small changes in behavior can give you an early warning that something is troubling them • Stay active. Go for a walk, volunteer with a community group, write a poem, play a musical instrument. Trying any of these can be a positive way to handle your emotions. • Stay in touch with family. If possible, stay in touch with trusted family, friends, and neighbors to talk things out and help deal with any stress or worry. • Take care of yourself. Losing sleep, not eating, and worrying too much can make you sick. As much as possible, try to get enough sleep, eat right, exercise, and keep a normal routine. It may be hard to do, but it can keep you healthy and better able to handle a tough time. ANY QUESTIONS???
