EKG stands for electrocardiogram. It measures electrical activity in the heart. EKGs are commonly performed before a doctor performs other diagnostic procedures such as cardiac catheterization (a procedure where a small tube is inserted into a blood vessel) or angioplasty (where a balloon is inflated within a narrowed artery). An EKG provides information regarding the functioning of the heart muscle. This includes measuring the rate and rhythm of the heartbeat.
Practice exams are meant to prepare students for real exam days. Practice exams are similar to actual exams except that they are not graded. Students may retake the exam until they pass. If they fail, they must wait until the next scheduled testing date.

An EKG machine records the electric impulses generated by the heart's muscle cells. Doctors use EKGs to diagnose problems with the heart. If doctors suspect that someone has a problem with his or her heart, they might order an EKG.
The EKG machine consists of two parts - the monitor and the electrodes. The monitor displays information about the patient's heartbeat. The electrodes measure the voltage produced by the muscles of the heart. The doctor places the electrodes on the skin near the patient's chest. He or she attaches wires to each electrode so that the signals recorded by the electrodes can be transmitted to the monitor. Then, he or she presses buttons on the monitor to record the results.
Not necessarily. Sometimes, surgeons perform surgery before ordering an EKG. However, it's important to know whether or not you've been diagnosed with a heart condition before undergoing major surgery.
Yes, anyone can perform an EKG. However, only a qualified technician can interpret the results.
No, not all hospitals have an EKG machine. Only certain kinds of hospitals have them.
No, an EKG does not measure heart rate. Instead, it measures the strength of the electric current flowing between the heart and the rest of the body.
Some common conditions detected during an EKG include arrhythmias, which occur when the normal rhythm of the heart isn't maintained; bradyarrhythmia, which occurs when the heart beats too slowly; tachyarrhythmia, which happens when the heart beats too fast; and ventricular hypertrophy, which occurs when the walls of the heart become thickened.
It depends on the person. Generally speaking, no. But, if you smoke cigarettes or drink alcohol frequently, you might want to stop doing those activities prior to getting an EKG.
An EKG machine records the electrical signals produced by the heart muscle cells during each heartbeat. The information recorded by the EKG machine is called an ECG tracing.
In order to interpret the results of an EKG, it's important to understand the normal patterns of cardiac rhythm. If you've ever taken a physical exam before, you know that doctors perform an EKG to check your heart rate and determine whether your pulse is strong enough to sustain blood flow throughout your body. Doctors also conduct an EKG to detect abnormalities in your heart rhythm.
Doctors use an EKG to diagnose conditions such as arrhythmias, myocardial infarction, coronary artery disease, and congenital defects. Arrhythmia refers to abnormal rhythms in the heart. Myocardial Infarction occurs when part of the heart tissue dies. Coronary artery disease causes blockages in arteries supplying oxygenated blood to the heart. Congenital defects occur when certain parts of the heart fail to develop properly.
Taking a practice test prior to receiving your official EKG report offers several benefits. First, it ensures that you fully comprehend the meaning of the results. Second, it lets you identify areas where you might need additional instruction. Third, taking a practice test enables you to compare your performance to previous attempts. Fourth, it allows you to gauge your progress towards passing the certification examination. Fifth, it makes sure that you don't forget anything vital. Sixth, it prevents you from spending unnecessary money on expensive study guides. Seventh, it saves you from wasting precious time studying subjects you already mastered. Eighth, it increases your chances of scoring higher on the actual certification exam. Lastly, it improves your overall knowledge base.
There are two main types of practice tests available today. One type includes questions based on the official format of the certification exam. The second type contains questions based on sample exams provided by the testing company.
An EKG machine measures the voltage produced by the electric current flowing between two electrodes attached to the skin. The information recorded during an EKG is called an ECG tracing.
There are three main types of electrodes used during an EKG procedure. First, disposable adhesive patches are commonly used. Second, reusable stainless steel needles are used. Third, gel-based electrodes are sometimes used. Adhesive patch electrodes are inexpensive and convenient. Stainless steel needle electrodes are reusable and ideal for patients who have allergies to latex. Gel-based electrodes are expensive and difficult to apply.
The type of electrode you choose depends on several factors. One factor is whether you plan to perform multiple tests or only one. If you plan to conduct multiple tests, it's important to purchase a set of reusable needles. Reusable needles are cheaper than disposable ones. Furthermore, they're safer because you won't risk getting stuck with a contaminated needle. Disposable needles are cheap and convenient. But, they pose health risks because they contain toxic substances. Lastly, you must decide which part of the body you wish to record the data from. For instance, if you plan to measure the heart rate, chest leads are required. Chest leads consist of four wires connected to the arms and legs. Each wire has its own specific function.
Before purchasing a set of electrodes, you should know where you intend to store them. Storage locations vary depending on the type of electrode you select. For example, if you plan to reuse the needles, you should store them somewhere safe so that they don't become damaged. Similarly, if you plan to dispose of the needles, you should ensure that they're properly disposed of.
Yes, you can perform multiple tests with just one pair of electrodes. All you need is a second pair of electrodes. Once you've completed the initial recording, simply switch the pairs of electrodes.
An EKG measures changes in voltage across your chest muscles during each heartbeat. Doctors use EKGs to diagnose problems related to your heart.
There are two main types of electrodes used during EKG testing. One type includes adhesive patches placed directly onto your body. The second type uses reusable gel pads. Both types of electrodes measure electrical signals generated by your heart muscle cells.
The adhesive patch electrode has several advantages. First, it's inexpensive. Second, it doesn't interfere with normal activities. Third, it's convenient because it requires no preparation before being applied. Fourth, it's safe because it does not cause discomfort. Fifth, it's reliable because it produces consistent results. Sixth, it's accurate because it records only the electrical impulses produced by your heart muscle cells. Seventh, it's portable because it can be removed quickly and easily. Eighth, it's flexible because it can be moved around freely. Ninth, it's reusable because it can be cleaned and reused multiple times. Tenth, it's noninvasive because it causes minimal pain.
An EKG measures the electric impulses generated by your heart muscle cells when they contract.
The word “electrocardiograph” comes from two Greek words: “elektron” meaning electricity and “kardia” meaning heart. So, an electrocardiograph literally means an instrument that measures the electric current produced by the heart.
An EKG machine is a special type of electronic equipment that allows doctors to record the electrical signals coming out of your body. These signals tell us about how well your heart is working.
A technician is a person who takes an EKG reading. Technicians must have specialized training and certification to perform this job.
An EKG strip is a paper form that contains information recorded by an EKG machine. Doctors use strips to diagnose problems with your heart.
An EKG report is a summary of all the results found on an EKG strip. A doctor will often ask you to fill out an EKG report after taking your EKG reading.
An EKG wave is a pattern created by the movement of your heart muscles during each heartbeat. Each wave looks like a sine curve. Waves look different depending on what part of the heart is being measured.
P waves are the first set of waves seen on an EKG. They occur at the beginning of every heartbeat. P waves are caused by the opening of the atria, or upper chambers of the heart. When the atria open, blood rushes into the ventricles, or lower chambers of the heart.
R waves are the second set of waves seen on an EKG. They appear between the P waves and QRS complex. R waves are caused by the contraction of the ventricles, or lower chambers of the heart. As the ventricles contract, blood flows back into the heart through the veins.
QRS complexes are the third set of waves seen on an EKG. They represent the depolarization of the myocardium, or heart muscle. Depolarization occurs when the heart muscle cells change their resting potentials to more positive values.
T waves are the fourth set of waves seen on an EKG. They follow the QRS complex and last longer than the QRS complex itself. T waves are caused by repolarization of the heart muscle. Repolarization causes the heart muscle to return to its original state.
PR intervals measure the amount of time between the start of a P wave and the start of the next P wave. If the PR interval is too short, then the heart has trouble pumping enough blood throughout the body. This can result in symptoms like dizziness, fainting, or even death.
