Which of these items are placed on the patients limbs and chest in an ECG to detect impulses?
DiagnosisTo diagnose angina, your health care provider will do a physical exam and ask questions about your symptoms. You'll also be asked about any risk factors, including whether you have a family history of heart disease. Show
Tests used to diagnose and confirm angina include:
TreatmentOptions for angina treatment include:
The goals of angina treatment are to reduce the frequency and severity of the symptoms and to lower the risk of a heart attack and death. You will need immediate treatment if you have unstable angina or angina pain that's different from what you usually have. MedicationsIf lifestyle changes — such as eating healthy and exercising — don't improve heart health and relieve angina pain, medications may be needed. Medications to treat angina may include:
TherapiesSometimes, a nondrug option called enhanced external counterpulsation (EECP) may be recommended to increase blood flow to the heart. With EECP, blood pressure-type cuffs are placed around the calves, thighs and pelvis. EECP requires multiple treatment sessions. EECP may help reduce symptoms in people with frequent, uncontrolled angina (refractory angina). Surgery and proceduresIf lifestyle changes, medications or other therapies don't reduce angina pain, a catheter procedure or open-heart surgery may be needed. Surgeries and procedures used to treat angina and coronary artery disease include:
Clinical trialsExplore Mayo Clinic studies testing new treatments, interventions and tests as a means to prevent, detect, treat or manage this condition. Lifestyle and home remediesHeart disease is often the cause of angina. Making lifestyle changes to keep the heart healthy is an important part of angina treatment. Try these strategies:
Preparing for your appointmentIf you have sudden chest pain (unstable angina), call 911 or your local emergency number immediately. If you have a strong family history of heart disease, make an appointment with your health care provider. Appointments can be brief, and there's often a lot to discuss. So it's a good idea to take steps to prepare for your appointment. Here's some information to help you get ready and what to expect from your health care provider. What you can do
Your time with your health care provider is limited, so preparing a list of questions will help you make the most of your time together. For angina, some basic questions to ask your health care provider include:
Don't hesitate to ask any other questions that you may have during your appointment. What to expect from your doctorYour health care provider is likely to ask you a number of questions. Being ready to answer them may save time to go over any information you want to spend more time on. Your health care provider may ask:
What you can do in the meantimeIt's never too early to make healthy lifestyle changes. Try these steps:
Which of these items are placed on the patient patient's limbs and chest in an ECG to detect impulses?Electrodes (sensors) are attached to the chest, arms and legs or sticky gel. These electrodes detect the electrical currents generated by the heart – these are measured and recorded by the electrocardiograph.
Which leads in an ECG monitor electrodes placed on a patients arms and legs?Leads I, II, III, aVF, aVL and aVR are all derived using three electrodes, which are placed on the right arm, the left arm and the left leg. Given the electrode placements, in relation to the heart, these leads primarily detect electrical activity in the frontal plane.
Which limb electrode is used as a reference point?By convention, lead I has the positive electrode on the left arm, and the negative electrode on the right arm, and therefore measures the potential difference between the two arms. In this and the other two limb leads, an electrode on the right leg serves as a reference electrode for recording purposes.
Where are the electrodes that precordial leads monitor placed?The Fontaine precordial electrodes are placed at the manubrium sternum, xiphoid and V4 positions (Fig. 4). The electrodes are connected to the right arm, left arm and left foot electrode connections of the electrocardiograph respectively [20].
