    Electrocardiogram (ECG or EKG)

    An electrocardiogram abbreviated as EKG or ECG is a test that measures the electrical activity of the heartbeat. With each beat, an electrical impulse (or wave) travels through the heart. This wave causes the muscle to squeeze and pump blood from the heart. A normal heartbeat on ECG will show the timing of the top and lower chambers. Dec 18, The electrocardiogram (ECG or EKG) is a noninvasive test that is used to reflect underlying heart conditions by measuring the electrical activity of the heart. By positioning leads (electrical sensing devices) on the body in standardized locations, health care professionals can learn information about many heart conditions by looking for characteristic patterns on the EKG.

    This wave causes the muscle tsst squeeze and pump blood from the heart. A normal heartbeat on ECG will show the timing of the top and lower chambers. An ECG gives two major kinds of information. First, by measuring whxt intervals on the ECG, a doctor can determine how long the electrical wave takes to pass through the heart. Finding out how dhat a wave takes to travel from one part of the heart to the next shows if the electrical activity is normal or slow, fast or irregular.

    Second, by measuring the amount whar electrical activity passing through the heart muscle, a cardiologist may be able to find out if parts of the heart are too large or are overworked. When the ECG stickers are removed, there may be some minor discomfort. Written by American Heart Association editorial staff and reviewed by science and medicine advisers.

    What Is an Electrocardiogram?

    Jan 25, An electrocardiogram is a simple, painless test that measures your hearts electrical activity. Its also known as an ECG or funslovestory.com: Danielle Moores. An electrocardiogram (ECG) is one of the simplest and fastest tests used to evaluate the heart. Electrodes (small, plastic patches that stick to the skin) are placed at certain spots on the chest, arms, and legs. The electrodes are connected to an ECG machine by lead wires. Resting lead EKG: This type of electrocardiogram is the standard test for measuring your hearts electrical function. Performed while you are lying still, this EKG records your hearts electrical activity from 12 electrodes (sticky patches) on your chest, arms, and legs at the same time.

If you are a new patient and want to request and appointment or need help finding a doctor, please call , Option 3. If you are a returning patient, call , Option 2, to request an appointment. Our doctors use several types of electrocardiograms EKG to check for a variety of cardiac heart or pulmonary lung conditions. The types of EKG we use at Stanford include:.

    This test is used to detect any cardiac or pulmonary diseases. Learn more about a cardiopulmonary exercise test. Exercise EKG stress test : A stress test also called treadmill test or exercise EKG is given while a patient walks on a treadmill or pedals a stationary bicycle to monitor the heart during stress ir exercise. Breathing and blood pressure rates are also monitored. Learn more about a stress test. Electrodes small, plastic patches are placed at certain locations on the chest, arms, and legs.

    When the electrodes are connected to an ECG machine by lead wires, the electrical activity of the heart is measured, interpreted, and printed out for the physician's information and further interpretation.

    Learn more about a holter monitor. A resting lead EKG can be part of a routine checkup to screen for heart conditions before any signs or symptoms develop. During this procedure, multiple ECG tracings are obtained over a period of approximately 20 minutes in order to capture abnormal heartbeats which may occur only intermittently. Learn more about a signal-averaged electrocardiogram.

    Patients may be asked to remove all jewelry from the neck and wrists. Prior to having an EKG, patients should avoid putting on skin cream or oil since it tends to interfere with obtaining a good EKG recording.

    Men are usually bare-chested during the test. Women are offered a gown. If patients are wearing stockings, they should take them off. Patients will lie on a bed or table. Small, sticky patches electrodes are placed on the chest, wrists and ankles. Areas on arms, legs, and chest where the electrodes will be placed are cleaned and may be shaved to provide a good contact with the skin.

    Patients will be asked to lie quietly while the EKG is recording. Patients should be able to resume normal diet and activities, unless the doctor instructs differently. Generally, there is no special care following an EKG. Notify the doctor if any symptoms you had prior to the test occur. These include chest pain, shortness of breath, dizziness, or fainting. The first short upward notch of the EKG tracing is called the "P wave.

    The next part of the tracing is a short downward section connected to a tall upward section. This next part is called the "QRS complex. The next short upward segment is called the "ST segment. The next upward curve is called the "T wave. Variations in size and length of the different parts of the tracing may be significant. The tracing for each lead of a lead EKG will look different, but will have the same basic components as described above. Each lead of the lead EKG is "looking" at a specific part of the heart, so variations in a lead may indicate a problem with the part of the heart associated with a particular lead.
