Ecg test results normal range

Electrocardiography (ECG) is one of the most vital and readily used screening tool in clinical medicine. It is inexpensive and easily obtained in both the inpatient and outpatient setting. The ECG is used to diagnose numerous cardiac conditions, including prior infarction and active cardiac ischemia, as well as conduction abnormalities such as atrial fibrillation and life-threatening tachycardias. The information provided by ECGs is also used in determining which type of implantable cardiac defibrillator should be used for the management of advanced heart failure. Numerous noncardiac conditions, including electrolyte abnormalities and medication side effects, are also detectable on ECG owing to their distinct effect on conduction patterns. [ A well-planned approach to 12-lead ECG interpretation will prevent the interpreter from missing crucial information. Key aspects in the interpretation of the 12-lead ECG include the heart rate, the heart rhythm (both atrial and ventricular), the electrical axis (both the P-wave axis and the QRS axis), and knowledge of the normal intervals. Next, determine the relationship of P waves to QRS complexes. Finally, analyze the QRS morphology and ST and T-wave segments. ECG paper commonly moves at 25 mm/second; thus, each small box (1 mm) is equivalent to 0.04 seconds (40 milliseconds), and each large box (5 mm) is equivalent to 0.2 seconds (200 milliseconds). At the beginning of an ECG, make note of the standardization square, normally 10 mm...

Chambers and valves of the heart Ejection fraction is a measurement of the percentage of blood leaving the heart each time it squeezes. When the heart squeezes, it's called a contraction. Ejection fraction is just one of many tests your health care provider may use to see how your heart works. The heart contracts and relaxes. When the heart contracts, it pumps out — ejects — blood from the two lower heart chambers, called ventricles. When the heart relaxes, the ventricles refill with blood. No matter how forceful the contraction, the heart can never pump all the blood out of a ventricle. The term "ejection fraction" is the amount of blood — as a percentage — that's pumped out of a filled ventricle with each heartbeat. The ejection fraction is usually measured only in the left ventricle. The left ventricle is the heart's main pumping chamber. It pumps oxygen-rich blood up into the body's main artery, called the aorta. The blood then goes to the rest of the body. According to the American Heart Association: • A left ventricle (LV) ejection fraction of about 50% to 70% is categorized as normal. • A mildly reduced LV ejection fraction is usually between 41% and 49%. • A reduced LV ejection fraction is usually 40% or less. Even if you have a normal ejection fraction, your overall heart function may not be healthy. Talk with your health care provider if you have concerns about your heart. Some things that may cause a reduced ejection fraction are: • Weakness of the heart muscle,...

Ejection fraction measures your heart’s ability to pump oxygen-rich blood out to your body. In a healthy heart, the fraction is a higher number. A low number means that your heart has difficulty keeping up with your body’s needs. If you have or are at risk for heart failure, your healthcare provider will want to know your ejection fraction. What is ejection fraction? Ejection fraction refers to how well your heart pumps blood. It is the amount of blood pumped out of your heart’s lower chambers (ventricles) each time it contracts. To understand ejection fraction, it’s helpful to understand how • Blood enters the heart through the top right section (atrium). • Between heartbeats, there’s a short pause. This is when blood flows through a valve down to the left ventricle. • Once the ventricle is full, the next heartbeat pumps out (ejects) a portion of the blood out to the body. What is a normal ejection fraction? Ejection fraction in a healthy heart is 50% to 70%. With each heartbeat, 50% to 70% of the blood in your left ventricle gets pumped out to your body. Ejection Fraction Percentage Normal Mildly Abnormal Moderately Abnormal Severely Abnormal Male 52% to 72% 41% to 51% 30% to 40% Below 30% Female 54% to 74% 41% to 53% 30% to 40% Below 30% Some people with a normal ejection fraction also have heart failure. This is known as heart failure with preserved ejection fraction (HFpEF). Why is it important to know my ejection fraction? Your ejection fraction is an indicator of ho...

A Holter monitor is a type of heart monitor that records your heart’s activity over 24 or 48 hours. If you have an irregular heartbeat or heart palpitations, but an EKG didn’t detect anything, a cardiac monitor can help diagnose the problem. You wear the Holter monitor while you do your daily activities. Your provider discusses the results with you. Overview What is a Holter monitor? A Holter monitor is a wearable device and type of This monitor is: • Small, about the size of a cellphone. • Battery operated. • Equipped with wires and electrodes (small patches) that stick to your skin. A Holter monitor records your heart’s electrical activity for 24 or 48 hours. While you wear it, you continue to do your regular daily activities. The Holter monitor is named for Dr. Norman J. Holter, who created it in the 1950s. Does wearing a Holter monitor hurt? No, wearing a Holter monitor isn’t painful. Who needs a Holter monitor? You may need a Holter monitor if you have an inconclusive Maybe you saw your doctor because of signs of a heart rhythm problem — like your heart is racing or fluttering. Or you had unexplained fainting. Your provider decided to do an EKG to find the problem. But the EKG only records your heart for a short period. Heart symptoms don’t always happen while you’re in the provider’s office. If the EKG doesn’t tell your provider what they need to know, a Holter monitor can help. It gathers more information about your heart’s activity. You wear it for a full day or tw...

Have you ever been curious about the meaning of all the wavy lines on an ECG report? Generally, a succession of waveforms representing various phases of the cardiac cycle makes up an electrocardiogram or ECG report. These waves represent the electrical impulses of your heart as they contract and rest. Knowing how to read an ECG report is crucial as the results may indicate some abnormalities and chronic heart conditions which require immediate treatment. It might appear difficult to understand and complicated initially, but with some information, it is simple to understand. Below we will learn how to study an ECG report and how to check if it is normal. Did you know that your heart is essentially an electrical pump? Your heart relies on a steady stream of electrical impulses to pump blood throughout your body. An ECG report provides a detailed interpretation of these electrical signals, helping healthcare professionals to diagnose and monitor a range of heart conditions including arrhythmias and heart attacks. They can also monitor the effectiveness of treatments and track changes in a patient's heart health over time. During this non-invasive test, small electrodes are placed on your chest, arms, and legs. These electrodes detect the electrical signals generated by your heart with each beat and transmit them to a machine that records the data. The resulting report is a graphical representation of these signals, showing the electrical activity of your heart over time. Read...
